ABSTRACT. Current challenges in soil erosion research have created demand for integrated, flexible, and easily parameterized sediment transport models. Most of the existing monolithic erosion models (e.g., WEPP and WEPS) are not modular, thus modifications require considerable time, effort, and expense. In this paper, the feasibility and challenges of using the Object Modeling System (OMS) for ...

As elicitors of terrestrial system change (e.g., land use transformation) through the introduction of anthropogenic causes, the spatial patterns and levels of roads might be more detrimental to the long-term health of ecosystems at a large scale than the road paving itself. This paper reveals the relationship between soil erosion and roads from a large-scale perspective in Jiangxi Province, Chi...

BACKGROUND Plants play a pivotal role in soil stabilization, with above-ground vegetation and roots combining to physically protect soil against erosion. It is possible that diverse plant communities boost root biomass, with knock-on positive effects for soil stability, but these relationships are yet to be disentangled. QUESTION We hypothesize that soil erosion rates fall with increased plan...

soil erosion is a serious environmental problem in vazroud watershed, which is located in the centre of the mazandaran province, iran. unfortunately, vazroud watershed like most iran watersheds don’t have recorded data and erosion and sedimentation gages to research, monitor and model soil erosion at large watershed. in order to assess the soil erosion risk, soil erosion modeling at the watersh...

maintaining soil productivity is one of the key factors in sustainable agriculture. soil erosion reduces soil productivity over a long-term period of time. therefore, determining soil erosion tolerance is necessary for sustainable agriculture production. in this study, the long-term effects of erosion on soil productivity in the typical kohin watershed were evaluated. the soil productivity inde...

The assessment of the soil redistribution and real long-term soil degradation due to erosion on agriculture land is still insufficient in spite of being essential for soil conservation policy. Imaging spectroscopy has been recognized as a suitable tool for soil erosion assessment in recent years. In our study, we bring an approach for assessment of soil degradation by erosion by means of determ...

There is a need in many emerging nations to develop simple methods for predicting areas of extensive soil erosion using imprecise, but real-world, input data at low cost with considerable Ž . accuracy. The objectives of this study are to 1 develop fuzzy logic models that predict soil Ž . erosion in a relatively large watershed using a limited number of input variables, 2 determine the Ž . effec...

We have developed a mass balance analysis of organic carbon (OC) across the five major river subsystems of the Mississippi (MS) Basin (an area of 3.2 3 106 km2). This largely agricultural landscape undergoes a bulk soil erosion rate of ;480 t·km22·yr21 (;1500 3 106 t/yr, across the MS Basin), and a soil organic carbon (SOC) erosion rate of ;7 t·km22·yr21 (;22 3 106 t/yr). Erosion translocates u...

This paper describes a method of soil erosion and soil movement measurements using 137Cs as a tracer. This technique has been used successfully employed for more than 30 years. Caesium-137 is a valuable tracer to study soil erosion. Its chemical and biological movement in soil is limited. Practically all redeposition of caesium-137 in soil after fallout occurs with soil particles due to strong ...

Wind erosion models have been used to assess policy impacts on soil erosion, but validation of models has been difficult until recently. We evaluated the Environmental Policy Integrated Climate (EPIC) wind erosion subm...
