<p>Erosion modeling is fundamental to land use management, water quality assessment and protection, reservoir sustainability, and agricultural system modeling. This study reviews the state of the erosion processes modeling, summarizing prominent models and assessing the need to develop a Decision Support System (DSS) at the watershed scale. Review of concepts of multidimensional erosion modeling shows a gap in our understanding of erosion processes and their modeling at the particle detachment scale and the upscaling of microscopic surface roughness and erosive processes from the laboratory scale to the field scale. Meta-analysis using VOSViewer software is also provided to analyze and visualize trends in erosion literature. Multi-dimensional erosion modeling in watershed hydrology requires further research in developing a multiscale-modeling framework for fundamental fluid-mechanical and soil-erosive constitutive behavioral processes from the microscopic scale to the macroscopic scale. The literature shows that erosion rate may be related to land use/land cover, slope, runoff, and catchment area at large scales.</p>
