Erosion and Sediment Transport Modeling: A Systematic Review

Abstract

Soil erosion and sediment transport have significant consequences, including decreased agricultural production, water quality degradation, and modification to stream channels. Understanding these processes and their interactions with contributing factors is crucial for assessing the environmental impacts of erosion. The primary objective of this review is to identify a suitable soil erosion and sediment transport model for catchment-scale application. The study considers various model selection processes, including model capability and the spatial and temporal domains for assessing spatiotemporal distributions. The review acknowledges the limitations, uncertainties, and unrealistic assumptions associated with soil erosion and sediment transport models. Models are usually developed with a particular objective, which demands an assessment of capabilities, spatial, and temporal applicability, and catchment-scale applicability. Distributed models are often preferred for catchment-scale applications, as they can adequately account for spatial variations in erosion potential and sediment yield, aiding in the evaluation of erosion-contributing elements and planning erosion control measures. Based on the findings of this study, the authors encourage utilizing models (such as Soil and Water Assessment Tool (SWAT) or Automated Geospatial Watershed Assessment Tool (AGWA)) that can forecast net erosion as a function of sediment output for catchment erosion and sediment yield modeling. This review helps researchers and practitioners involved in erosion and sediment modeling by guiding the selection of an appropriate model type based on specific modeling purposes and basin scale. By choosing appropriate models, the accuracy and effectiveness of sediment yield estimation and erosion control measures can be improved.

“…In addition, the literature review on modeling erosion and sediment transport indicates the significant implications of these processes for agricultural production, water quality, and changes in river channels. It is important to select an appropriate model for evaluation of these processes at the catchment scale, taking into account the spatial and temporal diversity of such phenomena [3].…”

“…Furthermore, the overtopping of the waves could result in silt incursion into the Lagoon (Phillips et al, 2017;Finotello et al, 2023). Understanding and estimating hydrodynamic behavior, as well as measuring erosion, deposition, and sediment transport over wide or restricted areas, are all possible with hydrodynamic and sediment transport modeling (Wibowo et al, 2020;Andualem et al, 2023;Visescu et al, 206). It has advanced quickly in recent decades from the 20th Century to the present, either experimentally or by model simulation, and is frequently used to predict the hydrodynamic response to low-crested buildings (Fattah and Damerianne, 2018).…”

Green and Low-Cost Modified Pisha Sandstone Geopolymer Gel Materials for Ecological Restoration: A Phase Review

“…Soil erosion has become one of the most serious and complex global issues, significantly affecting soil nutrients, land productivity, and carbon cycling in terrestrial ecosystems, and further generating unfavorable environmental and economic impacts [3,4]. At large spatial scales, soil erosion can increase sediment deposition in river channels and downstream reservoirs, thereby increasing the risk of flooding and potential water pollution [5,6].…”
