This research aims to develop a simulation model, for the operation of hydraulic and hydrological system of the Rima-Santa Eulalia River basin that includes the H. P. Huanza project now in construction, with purposes of power generation, water supply for agricultural use and drink water for population of Lima and Callao. The hydraulic system is formed by hydroelectric EDEGEL S.A. that operate using the regulated and unregulated flow of the Santa Eulalia river basin, Rímac river basin, Marcapomacocha Lake watershed and flows into the tunnel Trasandino infiltrators. We evaluated the operation of the project H. P. Huanza located upstream Sheque reservoir, in order to not affect the operation of H. P. Huinco EDEGEL property. The results obtained from the simulation model are acceptable for guaranteeing an average flow rate of 12.51 m3/s to be used by the H. P. Huinco and we can count on 95 ...

Since 2000, different cooperatives, mining enterprises and also some forms of informal clandestine exploitation have been performing heavy minery of gold in the high basin of Rio Grande, of the district of Ananea-Puno. The environmental impact comes from the residues or waste released from the mining activity, being the sediments the ones that cause it. Ways to solve this is impacts is through the construction of a dam to storage and hold these residues. In this sense, in order to design the dam and determine the volumes of sediments to be storaged, it was necessary to determine a series of monthly streamflow at the dam site axis. The high basin of Rio Grande doesn’t count with hydrometric o hydrographic stations, but precipitation occurred is measuring at Ananea´s climatology station. Because of this summary the present investigation uses precipitation - streamflow model to determine...
