The Water Erosion Prediction Project (WEPP) model is a physically based erosion simulation model built on the fundamentals of hydrology, plant science, hydraulics, and erosion mechanics. [ 1 ] [ 2 ] The model was developed by an interagency team of scientists to replace the Universal Soil Loss Equation (USLE) and has been widely used in the ...
Some erosion models are purely statistical, others more mechanistic (or physically based). Two of the more widely used soil erosion models in North America are the Revised Universal Soil Loss Equation (RUSLE) and the Water Erosion Prediction Project erosion model (WEPP).
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
where Q is the water discharge of the river [m 3 /s], and W is the width of the river channel [m]. Relative differences in long-term erodibility can be estimated by quantifying the erosion response under similar climatic and topographic conditions with different rock lithology.
In the 1930s, pioneers of erosion studies tightened control of their experiments by building the first rainfall simulators, [1] [2] ordinary sprinkle cans or pipes with holes. These holes were replaced in the 1960s with full cone nozzles, carefully selected to accurately approximate: The size of a rainfall water drop
Miami faces a dual threat: land subsidence and rising sea levels due to climate change – a combination that increases the city’s vulnerability to coastal flooding, storm surge and erosion.
[34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
Research shows that plunging in cold water 50 degrees or cooler has a number of benefits, including reducing inflammation and soreness, helping build resiliency, restoring balance to the nervous ...
