Literature Review On Remote Sensing Environmental Sciences Essay

Literature Review On Remote Sensing Environmental Sciences Essay Remote sensing is the science or art of acquiring information about the Earths surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. In much of remote sensing, the process involves an interaction between incident radiation and the targets of interest. (Dr. S. M. Rahman, 2001). Remote sensing makes it possible to collect data on dangerous or inaccessible areas. Remote sensing applications include monitoring deforestation  in areas such as the  Amazon Basin,  glacial  features in Arctic and Antarctic regions, and  depth sounding  of coastal and ocean depths. Military collection during the  Cold War  made use of stand-off collection of data about dangerous border areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed. Remote sensing exceedingly influences everyday life, ranging from  weather forecasts  to reports on  climate change  or  natural disasters. As an example, 80% of the German students use the services of  Google Earth. (Wikipedia, 2012) In recent time, with mans increasing interventions with the environment, the situation is aggravated. The quality of available data is extremely uneven. Land use planning based on unreliable data can lead to costly and gross errors. Soil erosion research is a capital-intensive and time-consuming exercise. Global extrapolation on the basis of few data collected by diverse and non-standardized methods can lead to gross errors and it can also lead to costly mistakes and misjudgements on critical policy issues. So, remote sensing provides convenient solution for this problem. Moreover, voluminous data gathered with the help of remote sensing techniques are batter handled and utilized with the help of Geographical Information System (GIS). (M. H. Mohamed Rinos, 2000) There are two different approaches that can be adopted for determining the characteristics of landslide from remote sensing data. The first approach determines more qualitative characteristics such as number, distribution, type and character of debris flow. This can be achieved with either satellite or air borne imagery collected in the visible and infrared regions of the spectrum. The next approach complements the qualitative characterization, estimating dimensions (e.g. length, width, thickness and local slope, motion, and debris distribution) along and across the mass movement. (V. Singhroy, 2004) Literature Review on Geographical Information System (GIS) Geographical Information System (GIS) is used to arrange the computer hardware, software, and geographic data. It helps the people interact, analyze, identify relationship and find the solutions to the problems. The system is designed to capture, store, update, manipulate, analyze, and display studied data and used to perform analyses (ESRI, 2005). Since 1970s, GIS has been used to analyze various environments. But the extensive application of GIS to hydrologic and hydraulic modeling and flood mapping and management begin from early 1990s. (Maidment, 2000). GIS has the ability to represent elevation in terms of topographic surfaces is central to geomorphological analyses and thus to the importance of representing topography using Digital Elevation Model (DEM). It is through the distribution of soil that the land surface changes over the long term and so the ability to link sediment transfer with DEM changes. (Schmidt, 2000) ArcView GIS desktop software provided the tools of map features that will affect a propertys value such as crime rates, environmental hazards, and the condition of surrounding neighborhoods and properties. ESRIs ArcGIS is a GIS which is working with maps and geographic information. ArcGIS software can be used for following functions: creating and using maps, compiling geographic data, analyzing mapped information, sharing and discovering geographic information, using maps and geographic information in a range of applications, and managing geographic information in database. (Wikipedia, ArcGIS, 2012). The ArcGIS provides tools for constructing maps and geographic information. Literature review on soil erosion Soil erosion is one form of soil degradation along with soil compaction, low organic matter, and loss of soil structure, poor internal drainage, salinization, and soil acidity problems (Wall, 2003). When the degradation of the soil is getting serious, it will contribute in accelerate the soil erosion. Soil erosion is a natural process; it usually does not cause any major problem to the environment. The soil is carried by the agents such as wind, water, ice, animals, and the use of tools by man. Soil erosion is a very slow process and even unnoticeable sometime, but it may occur at an alarming rate which causing the loss of topsoil. Farmers worldwide are losing about 24 billion tonnes of topsoil each year. In developing countries, because of the population pressure forces land to be more intensively farmed, the erosion rates per acre are twice as high as the standard. The soil erosion also will affect the productivity and growth. This is because when the soils are depleted and crops receive poor nourishment from the soil, the food provides poor nourishment to people. The rate of losses soil is faster than the creation of new soil. The difference between creation and loss represents an annual loss of 7.5 to 10 tonnes per acre worldwide. (DeHaan, 1992) The eroded soil that enters watercourse will reduce the water quality, reduces the efficiency of the particulars drainage system and also decreases the storage capacity of lakes. Sediment is the eroded soil that settles in the water systems. Accumulation of the sediment will reduce the capacity of a river or reservoirs to hold flood water. Thus, it requires a lot of money to clean the sediment often and manually. Sediment also can block the sunlight for aquatic plant and inhibit fish spawning. The water becomes not safe for drinking if there is runoff of chemical and nutrients from surrounding farmers fields. In Malaysia, soil erosion is a common natural occurrence. This is due to particular topography, soils and corresponding vegetation that predominate and the extensive rainfall that the country experiences. However, accelerated soil erosion is becoming a serious problem in Malaysia because of rapid land use developments. Various forms of erosion control have been proposed to develop the land in ways that are sensitive to its geography. (Abdullah, 2005) Literature review on Revised Universal Soil Loss Equation The development of Universal Soil Loss Equation (ULSE) initially was to assist soil conservationists in farm planning. They used ULSE to estimate the soil loss on specific slopes in specific fields. USLE was a guide for the conservationist and farmer to control the erosion if the estimated soil loss exceeded acceptable limits. Revised Universal Soil Loss Equation (RUSLE) is a science tool that has been improved over the last several years. It is based on USLE and makes some improvement on the equation. The RULSE has improved the effects of soil roughness and the effect of local weather on the prediction of soil loss and sediment delivery. (Revised Universal Soil Loss Equation, 2003). RUSLE can be used for site evaluation and planning purposes and to aid in the decision in selecting erosion control measure. The RUSLE provides numbers to substantiate the benefits of planned erosion control measures and also an estimate of severity of erosion. A = R.K.LS.C.P A is annual soil loss (tonnes/ha/year). R is rainfall erosivity factor. It is an erosion index for the given storm period (MJ.mm/ha/h) K is soil erodibility factor. It is the erosion rate for a specific soil continuous fallow condition on a 9% slope having a length of 22.1m (tonnes/ha/(MJ.mm/ha/h)) LS are topographic factor. It represents the slope length and the slope steepness. It represents the ratio of the soil loss from a specific site to that from a unit site (9% slope with slope length 22.1m) while other parameters are held constant. C is the cover management factor. It represents the protective coverage of canopy and organic material in direct contact with the ground. P is the support practice factor. It includes the soil conservation operations and other measure of control erosion. Literature review on USLE and RUSLE Table 2.1 Comparison of USLE and RUSLE (Renard, 1991) Factor USLE RUSLE R Based on long term average rainfall conditions for specific geographic areas Data from more weather stations and thus the value are more precise for any given location. RUSLE computes a correction to R. This is to reflect the effect of raindrop impact for flat slopes striking water ponded on the surface. K Based on soil texture, organic matter content, permeability, and other factors inherent to soil type. Adjusted to account for seasonal changes such as freezing and thawing, soil moisture, and soil consolidation. LS Based on length and steepness of slope, regardless of land use. Assigning new equations based on the ratio of rill to interrill erosion, and accommodates complex slopes. C Based on cropping sequence, surface residue, surface roughness, and canopy cover, with are weighted by the percentage. Lumps these factor into a table of soil loss ratios, by crop and tillage scheme. Sub factors (prior land use, canopy cover, surface cover, surface roughness, and soil moisture) are used. Dividing each year into rotation of 15 day intervals, then calculate the soil loss ratio for each period. The value need to recalculate if one of the sub factors change. RUSLE provides improved estimates of soil loss changes as they occur throughout the year, especially relating to surface and near surface residue and the effects of climate on residue decomposition. P Values change depending on the slope ranges with some distinction for various ridge heights. It is based on installation of practices that slow runoff and thus reduce soil movement. Values are based on hydrologic soil groups, slope, row grade, ridge height, and the 10 year single storm erosion index value. In RUSLE, it computes the effect of strip-cropping based on the transport capacity of flow in dense strips relative to the amount of sediment reaching the strip. The P factor for conservation planning considers the amount and location of deposition. Literature review on landslide Landslides are a type of soil erosion and major natural geological hazards. Each year, the landslide is responsible for enormous property damage which involves both direct and indirect costs. Malaysia experience frequent landslides. According to the local newspaper report in the years 2006-2009, along east coast highways in Peninsular Malaysia, in Sabah (East Malaysia) and in the island state of Penang, heavy rainfalls triggered landslides and mud flows. (Pradhan, 2009) Landslides happen when there are changes from a stable to an unstable condition in the stability of a slope. There are natural causes and human causes which contributing to a change in the stability of a slope. Natural causes of landslides include: Groundwater (pore water) pressure acting to destabilize the slope Loss or absence of vertical vegetative structure, soil nutrients and soil structure Erosion of the toe of a slope by rivers or ocean waves Weakening of a slope through saturation by snowmelt, glaciers melting, or heavy rains Earthquakes adding loads to barely table slope Earthquake-caused liquefaction destabilizing slopes Volcanic eruptions Landslides that are due to human causes are: Deforestation, cultivation and construction, which destabilize the already fragile slope Vibrations from machinery or traffic Blasting Earthwork which alters the shape of a slope, or which imposes new loads on existing slope In shallow soils, the removal of deep-rooted vegetation that bind colluvium to bedrock Construction, agricultural or forestry activities which change the amount of water which infiltrates the soil. (Wikipedia, 2012) Landslides in Malaysia are mainly triggered by tropical rainfall and flash floods. The rainfall and floods cause the rock to fail along fracture, joint and cleavage planes. The geology of Malaysia is quite stable but continuous development and urbanization lead to deforestation and erosion of the covering soil layers thus causing serious threats to the slopes (Pradhan, 2007). Abandoned project at hill sites for a certain period which affecting the maintenance of the slopes could causing the slopes to collapse. List of landslide events happened in Malaysia: 1 May 1961 A landslide occurred in  Ringlet,  Cameron Highlands,  Pahang. 21 October 1993 The man-made  Pantai Remis landslide  caused a new  cove  to be formed in the coastline. 11 December 1993 48 people were killed when a block of the  Highland Towers collapsed  at  Taman Hillview,  Ulu Klang,  Selangor. 30 June 1995 20 people were killed in the landslide at  Genting Highlands slip road  near  Karak Highway. 6 January 1996 A landslide in the  North-South Expressway  (NSE) near  Gua Tempurung,  Perak. 29 August 1996 A mudflow near Pos Dipang  Orang Asli  settlement in  Kampar,  Perak, 44 people were killed in this tragedy. 15 May 1999 A landslide near  Bukit Antarabangsa,  Ulu Klang,  Selangor. Most of the  Bukit Antarabangsa  civilians were trapped. 20 November 2002 The  bungalow  of the  Affin Bank  chairman General (RtD) Tan Sri Ismail Omar collapse causing landslide in  Taman Hillview,  Ulu Klang,  Selangor. December 2003 A rockfall in the  New Klang Valley Expressway  (NKVE) near the  Bukit Lanjan  interchange caused the expressway to close for more than six months. 31 May 2006 Four persons were killed in the  landslides  at Kampung Pasir, Ulu Klang, Selangor. 26 December 2007 Two villagers were buried alive in a major landslide, which destroyed nine wooden houses in Lorong 1, Kampung Baru Cina,  Kapit,  Sarawak. 12 February 2009 one contract worker was killed in a landslide at the construction site for a 43-storey condominium in  Bukit Ceylon,  Kuala Lumpur. 21 May 2011 16 people mostly 15 children and a caretaker of an orphanage were killed in a  landslide caused by heavy rains  at the Childrens Hidayah Madrasah Al-Taqwa orphanage in FELCRA Semungkis,  Hulu Langat,  Selangor. (Wikipedia, 2012) A scientific analyses of landslides need to be carry out to predict landslide-susceptible areas, and thus reduce landslide damages through proper preparation and mitigation. So, understanding landslides and preventing them is a serious challenge across worldwide. Literature review on past research and studies TITLE The application of GIS-based logistic regression for landslide susceptibility mapping in the Kakuda-Yahiko Mountains, Central Japan AUTHOR, YEAR Lulseged Ayalew, Hiromitsu Yamagishi, 2005 STUDY AREA Kakuda-Yahiko Mountains and their surroundings. OBJECTIVE / CONCEPT To study the landslide risk around the Kakuda-Yahiko Mountains. To study the use of logistic regression. To demonstrate the combination bivariate statistical analyses (BSA) to simplify the interpretation of the model. METHODOLOGY / METHOD Analytical approaches In LR or even in linear regression, it does little good to combine data with different measuring scales. Make sure that data have been normalized in a manner LR needs. Failure to do so generally leads to problems during the interpretation of the final results. Statistical results Overall model statistics of the regression conducted in this study using IDRISI. Coefficient positive indicating that they are positively related to the probability of landslide formation through the log transformation. Prediction probabilities and the construction of the susceptibility map In addition to the model statistics and coefficients, the final result of the regression process in IDRISI is a predicted map of probability defined by numbers that are constrained to fall between 0 and 1. The more these numbers are close to 1, the better they indicate the likelihood of finding the mapped landslides. Depending on the independent parameters considered, the landslide inventory map and the statistical approach used, the best predictor parameters and the predicted probability map of a logistic regression can vary considerably. OUTPUT / SUMMARY / RESULT Landslides are portrayed according to the types of movements namely slide, fall, flow, spread and topple. The principle of logistic regression (LR) rests on the analysis of a problem, in which a result measured with dichotomous variables such as 0 and 1 or true and false, is determined from one or more independent factors. TITLE Assessment of soil erosion and sediment delivery ratio using remote sensing and GIS AUTHOR, YEAR Weifeng ZHOU and Bingfang WU, 2008 STUDY AREA Upstream Chaobaihe River catchment, north China. OBJECTIVE / CONCEPT To develop monitoring of soil losses in the upstream Chaobaihe River Catchment. To develop a model by using Geographic Information System tools. To compute sediment delivery ratio (SDR) per hydrological unit. METHODOLOGY / METHOD Data Collection Remote sensing data, digital elevation model (DEM), and land use and land cover GIS data were used. Universal Soil Loss Equation (USLE) Simple empirical model, based on regression analyses of soil loss rates on erosion plots in the USA. The model is designed to estimate long-term annual erosion rates for agricultural fields. A = R ·K ·L ·S ·C A represents mean (annual) soil loss, R is the rainfall erosive factor, K is the soil erosibility factor, L is the slope factor, S is the slope length factor, and C is the cover management factor. OUTPUT / SUMMARY / RESULT The work indicated there are a number of advantages in using the modified USLE equation including the ability to combine it with a raster-based GIS to produce a cell-by-cell basis for mapping spatial patterns of soil erosion rates. The advantage of using a GIS raster based framework is that it allows one to quantify the impact of a single factor on the overall result and it can also easily be updated with improved datasets. TITLE Soil erosion hazard evaluation An integrated use of remote sensing, GIS and statistical approaches with biophysical parameters towards management strategies AUTHOR, YEAR Md. Rejaur Rahman, Z.H.

Just in Time Inventory Management Essay

Just In Time Inventory Management Definition: Just-in-Time (JIT) inventory management is the process of ordering and receiving inventory for production and customer sales only as it is needed and not before. This means that the company does not hold safety stock and operates with low inventory levels. This strategy helps companies lower their inventory carrying costs. Just-in-time inventory management is a cost-cutting inventory management strategy though it can lead to stock-outs. The goal of JIT is to improve return on investment by reducing non-essential costs. http://bizfinance.about.com/od/glossaryj/g/Just-In-Time-Jit-Inventory-Management.htm http://smallbusiness.chron.com/advantages-disadvantages-justintime-inventory-21407.html Advantages & Disadvantages of Just-in-Time Inventory by Neil Kokemuller, Demand Media Companies turnover significant inventory control to suppliers with just-in-time inventory. Related Articles * The Advantages of Just-in-Time Inventory Systems†¨ * Advantages & Disadvantages of Excess Inventory†¨ * Examples of Just-in-Time Inventory * Just in Time Inventory Definition * Advantages & Disadvantages of Matrix Organizational Structures in Business Organizations†¨ * The Disadvantages of Buy-Hold-Sell Inventory Just-in-time (JIT) inventory refers to an inventory management system with objectives of having inventory readily available to meet demand, but not to a point of excess where you must stockpile extra products. Maintaining inventory takes time and has costs, which is what motivates companies to implement JIT programs. Ads by Google Production management Comprehensive SCM, SRM & WMS Suite from Epicor. Learn More.Epicor.com / Distribution Customer Needs Balancing the goals of avoiding stock outs while minimizing inventory costs is at the heart of just-in-time inventory. One of the main benefits of automated and efficient inventory replenishment systems is that you can quickly respond to reduced inventory levels. Companies are now equipped to pull back on stock in a given product category and ramp up inventory in another as customer needs and interests change. Inventory Costs Minimization of inventory management costs is a primary driver and benefit of just-in-time practices. Inventory management has costs, and when you reduce the amount of holding space and staff required with JIT, the company can invest the savings in business growth and other opportunities, points out the Accounting for Management website. You also have less likelihood of throwing out product that gets old or expires, meaning reduced waste. Coordination A disadvantage of managing a just-in-time inventory system is that it requires significant coordination between retailers and suppliers in the distribution channel. Retailers often put major trust in suppliers by syncing their computer systems with suppliers so they can more directly monitor inventory levels at stores or in distribution centers to initiate rapid response to low stock levels. This usually means build up of technology infrastructure, which is costly. This coordinated effort is more involving on the whole than less time intensive inventory management systems. Risks Just-in-time inventory is not without risks. By nature of what it is, companies using JIT intend to walk a fine line between having too much and too little inventory. If company buyers fail to adjust quickly to increased demand or if suppliers have distribution problems, the business risks  upsetting customers with stock outs. If buyers over compensate and buy extra inventory to avoid stock outs, the company could experience higher inventory costs and the potential for waste.

But inflating inventory also carries significant disadvantages. The right inventory strategy for you depends on the business you’re in, your profits and losses and your ability to comfortably carry an inflated inventory. Analyzing your individual situation will tell you if the disadvantages of inflated inventory apply to you. Ads by Google Excel Spreadsheet Templates Fill-in the blanks & easily create any business document! Download NowBiztree.com Increased Costs The costs of inventory go beyond the purchase price of the goods or materials in your inventory. You must pay for space in which to store your inventory. If the inventory is perishable, you’ll rack up utility bills to heat and cool the space. You may need additional personnel to handle the inventory. If you buy materials or goods at a steep enough discount, your savings may be enough to offset these additional costs, but in many cases the cost of adding to your inventory cancel out your savings. Increased Taxes The Internal Revenue Service considers your inventory to be an asset, and you’re required to pay taxes on the inventory in stock at the end of the year. This is the reason you see many businesses hold Inventory Reduction Sales at year’s end. These businesses are looking to reduce their tax burden by selling off excess inventory. If, instead of selling off inventory, you’re focused on accumulating it, you could find yourself with a bigger tax bill. Before you build up your inventory, you should consider the possible tax implications of doing so. Spoilage Losses Most goods have a shelf life — a period after which they begin to deteriorate and spoil. For perishables such as food this can be a relatively short period. Durable goods have a longer shelf life, but even these can lose value over time. Fashions or household goods go out of style, fabrics fade  or are susceptible to damage from dust, insects or fire. If you build up too much inventory, you could be left with a quantity of useless goods on hand, resulting in a loss. Other Considerations When you increase your inventory because you come across a good deal on goods or materials, or because you think the prices will increase in the future, you’re gambling that your predictions about the future will come true. If, for example, the price of the goods and materials falls, you’re left holding an inventory of items for which you paid more than the current market rate. If you decide to inflate your inventory, double and triple check the information that led you to believe doing so was a good idea, and consider all the implications to your bottom line.

Related Articles * Inventory & Work Order Systems * An Introduction to Inventory Management Systems * The Advantages of Just-in-Time Inventory Systems†¨ * Examples of Just-in-Time Inventory * Just in Time Inventory Definition * Advantages & Disadvantages of Just-in-Time Inventory Companies use a Just-in-Time manufacturing and inventory management system to improve the efficiency of the company and reduce costs. The system requires manufacturers to purchase only when customer orders create a demand. Companies must develop a relationship with vendors to ensure parts reach the facility in time to manufacture products for the customer request. Businesses only produce inventory when there is a customer order in place. The system does not allow the business to produce or store excess inventory. Just-in-Time systems work in large and small organizations and those that produce products or services. With adjustments, the principles of Just-in-Time inventory management and manufacturing can work in any business. Ads by Google Systems engineering Production & Process Manager Jobs Submit Resume to Apply Now!Monster.com.sg / Systems+engineering Reduce Inventory Costs Using a Just-in-Time inventory system reduces the amount of material on hand in the production facility. Companies can reduce the cost to store and maintain excess inventory and eliminate the risk of materials becoming obsolete while in storage. High inventory quantities tie up company funds, which could otherwise benefit other areas of the business such as the research and development of new products. With the reduction in inventory costs, companies can expand and grow their businesses. Lead Time Reduction Just-in-Time manufacturing also uses a pull system to move materials through the production cycle. For example, in a manufacturing business, materials do not move to the next step on an assembly line until that step or station is ready. This reduces the stockpiling of unfinished product at any stage in the production process. When the company eliminates bottlenecks, production speed or lead-time is faster. Process engineers must determine the maximum quantity any station in the production process can have waiting. While workers may sit idle waiting to move production to the next step, the process is more efficient. Efficient Manufacturing Layout Companies must create a layout on the production floor to move materials through the process efficiently. Some companies must move workstations closer together to eliminate steps in the work process. This leads to a more efficient manufacturing layout that can significantly reduce lead tIme. Building products efficiently is a primary focus for a company implementing a lean manufacturing system. Improve Customer Satisfaction Companies implement a Just-in-Time system or lean manufacturing to satisfy the demands of customers. The voice of the customer is always present in a Just-in-Time manufacturing environment. Reductions in lead time and costs can help a company deliver a product to the customer faster and for a lower price.
