Gully erosion is one of the advanced forms water erosion. Identifying effective factors and gully predicting important tools to control manage such phenomenon. The main purpose this study evaluate effect four different resampling algorithms including cross-validation (5-fold 10-fold) bootstrapping (Bootstrap Optimism bootstrap) on boosted regression tree (BRT), support vector machine (SVM), ran...

Abstract Gully mapping techniques successfully identify gullies over a large range of breadths and depths in complex landscapes but practices for estimating gully volumes need further development. gap-interpolation estimation volume does not often factor landscape microtopography the generation new surface. These approaches can thus overestimate classical volumes, averaging depressions, or unde...

Incision as a result of fluvial erosion is an important process to model when simulating landform evolution. For gullies, it apparent that coupled with the processes cause incision there must be range stop incision. Once started, rills and gullies will grow infinitely without reduction in support area and/or being arrested by deposition armouring. Some these have been well studied under heading...
