Soil erosion modelling: A global review and statistical analysis
2021年8月1日 · A subset of GASEMT data with complete inputs that included (i) modelled soil erosion rates (Mg ha −1 yr −1), (ii) geographical coordinates, and (iii) the size of the study area (km 2), allowed statistical insights to be gained into soil-erosion model prediction patterns and trends through space and time. Excluding continental and global ...
Soil Erosion Modeling with the RUSLE Method - ArcGIS StoryMaps
2023年5月27日 · The Revised Universal Soil Loss Equation (RUSLE) is a well-documented empirical equation to model soil erosion. The RUSLE method is a multi-criteria analysis based on five factors: (1) rainfall erosivity (R), (2) soil erodibility (K), (3) slope length and steepness (LS), vegetation cover (C) as well as land use and farmland state (P) for the ...
Soil Erosion Models - an overview | ScienceDirect Topics
The European soil erosion model (EUROSEM) is a dynamic model used to evaluate soil erosion, runoff, solute transport and land degradation of the soil surface from the scale of pedons to that of small catchments. In comparison with other mathematical models, ...
The WEPP erosion model computes soil loss along a slope and sediment yield at the end of a hillslope. Interrill and rill erosion processes are considered. Interrill erosion is described as a process of soil detachment by raindrop impact, transport by shallow sheet flow, and sediment delivery to rill channels.
Towards multi-model soil erosion modelling: An evaluation of the ...
2024年1月1日 · Hence, the Erosion Potential Model (EPM) that also accounts for other erosion processes (e.g., gully erosion or soil slumps) and not just sheet and rill erosion (e.g., USLE-type models) can be an interesting option to estimate global and large-scale soil erosion rates especially because these processes can be important for the erosion-sediment ...
Abstract— Soil erosion is a global environmental problem influenced by both natural and human factors. Modeling provides a quantitative and consistent approach to estimate soil erosion and sediment yield under a wide range of conditions, and is needed to guide the comprehensive control of soil erosion. Over the years
Principles of Soil Erosion Risk Modeling - IntechOpen
2023年6月16日 · Soil erosion modeling is developing due to the availability of highly precise geographical and meteorological data for monitoring intra-annual fluctuations in temperature, vegetation, and management practices. Accurate soil erosion modeling is required to make informed decisions about planning, management, and policy at both small and large ...
Soil erosion modelling: A global review and statistical analysis
2021年8月1日 · This GASEMT database provides comprehensive insights into the state-of-the-art of soil- erosion models and model applications worldwide. This database intends to support the upcoming country-based United Nations global soil-erosion assessment in addition to helping to inform soil erosion research priorities by building a foundation for future ...
A New Approach for Smart Soil Erosion Modeling: Integration of ...
2022年10月14日 · Despite advances in artificial intelligence modeling, the lack of soil-erosion data and other watershed information still limits soil-erosion modeling. The limited number of parameters and a lack of evaluation criteria are major disadvantages to the use of empirical soil-erosion models. To overcome these limitations, we introduce a new approach that integrates …
