The production of sediments in basins is closely linked to the process of erosion, in fact, this increases with deforestation, consequently the concentration of suspended sediments also increases (Stott and Mount, 2004), which are deposited at the bottom of the channels, raising their level, significantly increasing the risk of flooding (Kramer et al. , 1997). While not all of the sediment settles on rivers, much of the material is transported downstream to the sea, where the rest of the particles settle. This causes hydraulic structures to become filled with sediments, reducing their productive life (Manson, 2004). Appropriate basin management requires estimation of both runoff and sediment production. This makes it possible to propose measures to increase water infiltration into the subsoil, control excess runoff, manage currents and reduce erosion, through soil protection (Raghuwanshi et al. , 2006). There are different methods for estimating sediment production in basins: methods based on direct measurement and methods based on mathematical modelling. The latter in turn are divided into methods: empirical, stochastic and simulation of physical processes. Physical process simulation methods can improve accuracy, but due to the large amount of data required, their use has been limited (Simons and Sentúrk, 1992). In this monographic work he proposes to evaluate the volume of sediments produced by water erosion through an empirical model called Potential Soil Erosion Method (EPM), also known as the Gavrilovic Method (Gavrilovic, Z. 1972). The method considers 6 factors that depend on the geological surface, soil properties (erodability factor), topographic factors (average slope), climatic factors such as annual mean precipitation, annual mean temperature, distribution and type of land use, to which is added a factor called degree of erosion. the volume of sediments (G) in the Quilca, Chilli and Vitor basin located in the Arequipa region, can be estimated using prediction techniques, such as the Gavrilovic equation, which relates production (W) and retention coefficients (W). sediments in a basin. The sediment production value obtained was 1 675 439. 11. 65 (m3/km2/year). The mean value of R was 0. 078 indicating that of the total sediment production in the basin, 7. 8% goes to transport and the rest would be retained within the basin, in the different sub-basins.
