“…Water erosion is divided into the processes of detachment, transport and deposition of soil particles (Kohnke and Franzmeier, 1994;Merritt et al, 2003). These general principles of erosion have been manifold described and integrated in models (Jetten et al, 2003(Jetten et al, , 1999Lørup and Styczen, 1996;Merritt et al, 2003;Renard et al, 1991;Williams and Berndt, 1977). A full review of strengths and weaknesses of different models and recommendations for the choice of a model is provided by Merritt et al (2003).…”

“…Many models have been developed to estimate and evaluate erosion and sediment yield problems [39] due to the model uncertainty, the assumptions and parameters that are unsuitable for local conditions [8]. Erosion models are designed for describing the erosion process and controlling factors with a specific model objective and output.…”

“…Conceptual models combine broad descriptions of catchment processes by incorporating the detailed catchment characteristics, physical processes of runoff generation and sediment transport into their conceptual structure. The limitation of these models is their poor representation of physical processes [39].…”

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.

“…All models (conventional and modern) under real conditions are more or less incorrect [13,14], because of the abstractions and simplifications of the original complex and nonlinear hydrologic processes [15]. It is very difficult to measure all the model parameters precisely, they are always data based.…”

Sediment particles, a product of erosion in the catchment are transported along the river with flowing water. The construction of Weir, barrage or a dam causes obstruction to the flow resulting in reduction of velocity. The reduced velocity causes sedimentation resulting in reduction of storage capacity which affects the overall life of the reservoir. The sediment deposition in the reservoir is a continuous and complex process which affects the useful life of a reservoir. The quantification of sediment deposition in a reservoir is necessary for effective reservoir and river basin management. The present study has been carried out to assess sediment deposition in Koyna Reservoir which is located in the Western Maharashtra, India. In India most of the rainfall is caused due to the southwest monsoon during the period from June to September, massive convective thunderstorms dominate the weather. In the present study analytical methods are used for estimation of sediment deposited in the Koyna reservoir. For the prediction annual inflow data is used. The storage capacity of Koyna reservoir is calculated considering the loss of storage due to sediment deposition for a period from 1961 to 2375. The results obtained indicated a loss of reservoir capacity by the year 2004, as 267.25 Mm 3 (9.55%). The physical measurement indicated that the Koyna reservoir had lost 293.09 Mm 3 (10.48%) of its capacity by the year 2004. The results obtained by analytical method have 8.82% error compared with the actual measurements.
