It is of great significance to dynamically simulate and forecast the development and evolutionary of soil erosion process. Traditionally, most of soil erosion models are essentially steady-state models. Thus, they have limitations at real-time simulation on the initiation and development of soil erosion process. Cellular Automata (CA), with a “from down to up” dynamic modeling framework, is cap...

Water erosion causes reduced farmland productivity, and with a longer period of cultivation, agricultural productivity becomes increasingly vulnerable. The vulnerability of farmland productivity needs assessment due to long-term water erosion. The key to quantitative assessment is to propose a quantitative method with water loss scenarios to calculate productivity losses due to long-term water ...

soil conservation is one of the most important regulative functions of natural ecosystems. this function is of high importance in taleghan watershed due to high erosion quantity and sediment accumulation in taleghan dam reservoir. soil loss reduction, sedimentation control and fertility conservation were considered as different aspects of soil conservation. effect of land use and vegetation cov...

Forest Watersheds provide timber and water, wildlife and fisheries habitat, and recreational opportunities. However, not an entire watershed is equally suited for each activity. Steeper slopes may be better left forested and used for wildlife habitat while more gentle slopes of the watershed could be used for timber production. Logging steep slopes can lead to soil erosion that can.seriously de...

Soil erosion is one of the biggest global environmental problems. Finding new innovative systems to measure soil erosion more accurately is a priority. An effort is being carried out in this study to use automated electronics in order to systematically and accurately measure soil erosion. In addition, the frequent measurements taken will help collect a large amount of data on soil erosion. The ...

Soil erosion and declining productivity resulting in low farm income have been the major constraints to the sustainability of the commercial vegetable production systems in cultivated uplands of the Philippines. Steep slopes, favorable climate, high fertilizer and pesticide application rates characterizes these production systems. Sustainability of upland vegetable production system and soil co...

BACKGROUND AND OBJECTIVES: The study explored the capability of the geographic information system interface for the water erosion prediction project, a process-based model, to predict and visualize the specific location of soil erosion and sediment yield from the agricultural watershed of Taganibong. METHODS: The method involved the preparation of the fou...
