Résumé
The present work aims to determine the storage capacity required for future reservoir in Vichaycocha subbasin, called “Purapa” reservoir, which will seek to increase the water supply in Chancay-Huaral basin uring the dry season. (M) The method used to calculate the active storage of the reservoir was "sequent peak analysis", in which inflows and outflows from the reservoir should be set previously. Simulation of natural flows in the river from the drainage basin was performed by precipitation-runoff model "soil moisture method" that is incorporated in the Water Evaluation and Planning (WEAP) software. Data from Santo Domingo flow gauge were used for calibration and validation of the hydrological model. On the other hand, water demand comprises ecological flow and requirements for agricultural and population purposes. (R) As a result, an active volume of 6.0 mcm (six million cubic meters) was obtained for Purapa reservoir and through the simulation of the reservoir it was verified that this capacity allows a water demand coverage and reliability of almost 100% (C) It is concluded that the sequent peak analysis is a simple method that allows to determine the storage capacity of Purapa reservoir, a result that should be considered as a first approximation in the feasibility study of the project.
