“…For instance, applied the classic USLE method to analyze the long-term intensity of reservoir siltation in relationship to environmental changes, while Barteni et al (2021) used a modified form of the equation (MUSLE) to predict future response of a small alpine catchment to single heavy rainfall. Other authors attempt to improve the method by introducing new parameters or their new interpretations (Tsige et al 2022, Shi et al 2022.…”

Predicting and estimating sediment yield from the catchment is crucial for the effective management of water resources and controlling soil erosion. Universal Soil Loss Equations (USLE) and their modifications have been appreciated and commonly applied among many methods. The idea of this work is to use the ESDAC database (a web platform hosting a series of pan-European and global datasets on soil erosion) to build the modified form of the USLE for the Zagożdzonka catchment, a small agricultural area located in central Poland. The calculated sediment yield is compared with the one determined based on the reservoir survey. The conducted analyses show that the average annual suspended sediment yield from the study catchment estimated using the MUSLE equation accounts for 201 Mg and is close to that determined based on the reservoir survey, i.e., 248 Mg. However, MUSLE, with the initially proposed parameters, will overpredict sediment transport at the study site. The ESDAC database may support local studies concerning soil erosion and sediment transport. The research is helpful for policymakers, planners, and engineers.

“…A commonly applied method for soil erosion and sediment yield estimation from non‐build‐up areas is USLE equation or its further modifications (McCool et al, 1987; Tsige et al, 2022; Wischmeier & Smith, 1978). This method requires inputs on rainfall and runoff erosivity, soil types, land cover, topography and support practices.…”

Small urban areas, due to their specificity (high anthroposphere, multiple forms of land use, variable drainage conditions), are often overlooked in studies on soil erosion and sediment transport that predominantly focus on a large scale. The sediment yield from such small urban areas may greatly vary depending, for example, on the state of the land development. Therefore, its proper estimation is crucial for water resources management, improving urban runoff quality or designing and maintaining local retention ponds. In this study, two different approaches were applied to estimate sediment yield from a small urban catchment of Służew Creek, located in Warsaw, Poland. While the first was based on direct hydrological measurements and field samples, the second (indirect) used various empirical formulas to predict bed load transport (local formula of Skibiński) in the stream channel and the suspended sediment delivery from the catchment (USLE equation, Build‐up/Wash‐off model). The sediment load established according to the direct approach equals 714 Mg/year, of which 83 Mg/year results from the bed load transport and 631 Mg/year comes from the suspended sediment transport. The total sediment load calculated according to the indirect approach equals 579 Mg/year. The relative difference in loads calculated with these two methods is about 20%. This paper combines various established methods into a novel composite analysis of sediment yield. The methodology presented in this study may support the estimation of sediment load in small urban catchments with a heterogenous land use structure. Hence, it may support urban planning and water resources management in such small catchments.
