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 ...
Rainfall simulator showing the effect of crop canopy on erosion. A rainfall simulator is used in soil science and hydrology to study how soil reacts to rainfall.Natural rainfall is difficult to use in experimentation because its timing and intensity cannot be reliably reproduced.
Danny Lee Fread (July 17, 1939 - February 5, 2009) was an American hydraulic engineer and Senior Research Hydrologist, best known for his computer-based mathematical simulation programs for rainfall and runoff to forecast the flow of flooding rivers and dam failures.
It simulates surface water and groundwater hydrology, erosion and sediment transport. The GSSHA model is used for hydraulic engineering and research, and is on the Federal Emergency Management Agency (FEMA) list of hydrologic models accepted for use in the national flood insurance program for flood hydrograph estimation.
Few soil erosion models consider gully erosion, mostly due to difficulties in modelling these large erosional features. Several studies have evaluated the ability of soil erosion models to realistically predict measured rates of erosion, mainly on agricultural landscapes. There is often a wide discrepancy between predicted and observed erosion ...
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.
Results of the study indicate that Black women in the U.S., ages 66-75, saw the largest decrease in obesity between 2022-2023.
MIKE 21C can be used for designing protection schemes against bank erosion, evaluating measures to reduce or manage shoaling, analyzing alignments and dimensions of navigation channels for minimizing capital and maintenance dredging, predicting the impact of bridge, tunnel and pipeline crossings on river channel hydraulics and morphology, optimizing restoration plans for habitat environment in ...
