The Lurín river, located in Lima, presents high levels of contamination, due to the increase in water demand as a result of the population increase, inadequate handling of solid waste, and discharges of wastewater (treated and untreated). Therefore, the present research work aims to model water quality using the Streeter-Phelps mathematical model, for which the collection of information on: dissolved oxygen, biochemical oxygen demand, temperature, speed, tension was carried out. and river width in 13 monitoring points of the lower part of the river, in addition, the digital elevation model was elaborated using images obtained from an unmanned aerial vehicle, topography and satellite images of the study area. With this information, the hydraulic characteristics of the river were obtained through the HEC-RAS program, with which the modeling of dissolved oxygen, biochemical oxygen demand was carried out, as well as the deoxygenation, re-aeration and sedimentation parameters of the sections of the river. river, in the Excel program with its Solver add-in, which made it possible to predict the behavior of DO and BOD to later carry out the simulation of scenarios with alternatives for improvement for the quality of the water resource, among which is the optimization of Wastewater Treatment Plant San Bartolo treatment and the implementation of a WWTP in Pachacamac district so that the river meets the water quality standards because the studies carried out reliably show that the river does not comply with current regulations, for which it is expected that with the scenarios proposed it is possible to recover the quality of the water in the lower part of the Lurín river.
