please tell me the various methods for determining the washout of soils?
Interested in various methods and approaches to determining the degree of soil erosion as a result of surface runoff of melt water. For example, by reducing the thickness of the humus horizon or reducing the values of organic carbon.
I’m sure there are quite a few methods. For predicting for the most part, I have used the RUSLE (Revised Universal Soil Loss Equation). It takes some calibration of the factors to suit your soils, cover and practices. Another is the SEPP ((Soil Erosion Prediction Project), but when I used it it required intense information. I think it may have been improved for easier uses. Our paper on Sediment From A Small Ephemeral Gully is more of a direct measurement using filter fabric fences to collect sediment for later measurement estimates, The Hazel Pistol Erosion Plot Study was measuring after severe fuel burning effects after clearcutting. The Offsite Loblolly Pine Removal and Restoration Analysis (about 2013) shows how I used the RUSLE to estimate soil erosion from various sized hydrologic units based on proposed activities. The various gully stabilization papers may offer some ideas on how to repair severely eroded lands to better function. I uploaded much of our work into Researchgate. We tried to include quality citations when possible.
Erosion modeling programs are known to us. How do you determine the degree of erosion (lightly eroded or heavily eroded soil)? In Russia, this is traditionally determined by the change in the thickness of the horizon A, where the standard is not eroded soil.
