Abstract: Sediment delivery represents the link between soil erosion within catchments and sediment yield in river networks. It is often estimated using the sediment delivery ratio (SDR) or other lumped parameter models. However, its proper quantification remains challenging due to the complex interplay of factors like lithology, geomorphology, weather, and land cover. Although empirical models have traditionally been used and sometimes adapted to provide spatially distributed estimation, advancements in catchment-scale modelling and remote sensing have expanded estimation capabilities, especially in recent years. This work aims to quantitatively analyse a list of 1,478 studies on sediment delivery modelling derived from Elsevier's Scopus database and published from 1960 to 2023. These studies are classified based on spatial and temporal scales, modelling approaches and processes considered. The findings will provide a comprehensive overview of the state of sediment yield modelling, offering insights into which factors have been considered and which models and approaches have been preferred so far. Here, an overview of the adopted framework is introduced, while the outcomes are still under examinations.
