A new paradigm of simulating suspended sediment load (SSL) with a Land Surface Model (LSM) is presented here. Five erosion and SSL algorithms were applied within a common LSM framework to quantify uncertainties and evaluate predictability in two steep, forested catchments (>1,000 km2). The algorithms were chosen from among widely used sediment models, including empirically based: monovariate ra...

Water erosion is a natural fact in the cycle of shaping earth’s landforms and most evident form of land degradation on a planetary scale (Roose & De Noni, 2004; Dautrebande Sohier, 2006; Toumi et al., 2013; Azaiez, 2020a). Its effects have largely affected rural landscape. Although it result of an ancient primeval climatic tectonic forcing, man’s footprint its intensification remains reali...

This study has evaluated the runoff and erosion rates in torrents of Southern Italy, two forested headwaters with very similar climatic, hydrological geomorphological characteristics; one headwater, 15 check dams were installed mid-1950s, while other is not regulated engineering works. To this aim, variables have been modeled over years after dam installation using HEC-HMS (Hydrologic Engineeri...

One of the main factors of water erosion is the natural characteristics of the soil called "erodibility" or"detachability". The present study aims to analyze the variations of soil erodibility factor in different plains and thefactors related to it. Erodibility is one the key factors in some models of erosion and sediment such as Universal SoilLoss Equation (USLE), Revised USLE (RUSLE), and Mod...
