On the riverbed of Mantaro river, precisely, on the area between La Oroya and 40 km, exist a communication between the cities of lima and Huancayo, where are located: many bridges, the central highway, several hydraulics structures for agricultural use, settlements urban town - La Oroya mining and La Oroya city. All of them exposed to flooding problems caused by maximum flood flows generated in the middle and upper basin of the Mantaro river. In this research we have determined the maximum flood in this area in order to provide security of the entire road infrastructure and existing waterworks. This calculation is very important to prevent the undermining of the design of hydraulic works, infrastructure located at the edge of the river, strengthening of the pillars of bridges, strengthening barrage of intakes, dams and gabions of the same.The results had In this research we have obtained...

This research was made in the hydraulic system of the Hydropower Plant Machupicchu, which has water reserves stored in Sibinacocha lake with a maximum capacity up to 100 million cubic meters. The power plant Mahupicchu was buried in February 1998 by slipping the Ahobamba streams, initiates a first stage of recovery in 2001 achieving sustained generate up to 90 MW and guaranteed by the reserves of the Sibinacocha lake. In the second stage of rehabilitation, initiated in 2009, it aims to increase the generation of 90 MW to 180 MW requiring 61 m3 /s in times of ood and drought, which means requirements higher water volumes stored in Sibinacocha lake. The research simulates the operation of the lake for 47 years (1965 to 2011) considering the requirement of the first and second stage of rehabilitation. The simulation was done with the model Reservoir System Analysis (HEC-3). The simulation r...

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...
