MAXIMO, Caicedo, et al. Generation of Flows Applying a Simple Method of Flood Routing to Monthly Level in La Leche Basin, Peru. Rev Politéc. (Quito) [online]. 2024, vol.53, n.1, pp.99-110. ISSN 2477-8990.  https://doi.org/10.33333/rp.vol53n1.09.

The flood routing is generally used in the analysis and evaluation of floods; however, it has been scarcely explored in the extent and determination of flows. Therefore, this research aimed to generate flows applying a simple method of flood routing known as Muskingum to monthly level, in the La Leche basin of Peru. The basin in question was chosen, since in the last 40 years it has suffered major floods, affecting a large part of the population, farmland and local infrastructure, which is why it is necessary to address its study. The methodology was of applied type and comparative non-experimental design. Due to the fact that the flood routing uses the parameters of proportionality of volume and weighting of routing in defined intervals of time, it was considered convenient to use statistical indicators to optimize the comparison of the flows registered in the hydrometric stations and the hydrographs of the simulation of a hydrological model rainfall-runoff type for different return periods, obtaining significant results in each case, according to the Pearson correlation, the Schultz criterion, the Nash-Sutcliffe criterion, the mass balance error and the t-test for two samples assuming equal variances. Finally, it is concluded that flows can be established using the flood routing with the Muskingum method in the La Leche basin, and can also be used in simulated discharges where meteorological and hydrometric information is available.
