Representing the role of soil moisture on erosion resistance in sediment models: Challenges and opportunities

Soil's resistance to erosion or its susceptibility resist detachment is a key parameter in the majority of soil and sediment models. Although function both intrinsic properties dynamic environmental variables (e.g., moisture), influence latter seldom explicitly incorporated definition resistance. The significant complex role moisture content on recognized by many studies, however, much emphasis regarding yield modeling has been impacts runoff generation rather than In this paper, we synthesize existing state knowledge processes mechanisms which affects soil, highlight challenges opportunities associated with incorporating relation assessment Through detailed analysis literature, find that dry lowest thus high erodibility, increases (erodibility decreases) increasing antecedent until certain threshold. After threshold reached, decreases further increase content, soils become more susceptible erosion. Next, study identifies candidate may be used quantitatively represent soil's vis-à-vis moisture, discuss frameworks. As way forward, through meta-analysis published data, develop an exemplar could variation content. We parameters such vary significantly across types, raising possibility for developing soil-type based moisture-resistance relations. Overall, review underscores considerable impact soils, makes case integrating into predictive
