Hidrología de las cuencas de aporte a Yaciretá. Análisis de precipitaciones

Abstract

As a part of the activities of the Study “Provision of the Hydrometheorologic network and Flow Forescasting System of Yaciretá”, this paper presents the analysis of precipitation stations in the zone of influence. Of a19 stations with available data, 4 only possess a longitude of approximately 65 years of data: they are the stations Cerro Azul, Encarnación, Villarrica y Montecarlo. On the other hand, a group of stations with a longitude of approximately 30 years series and the 10 years the rest. The analysis from the precipitations to annual level and monthly level their realized. For the calculation of the precipitations monthly the stations were grouped in North Zone, Central Zone and South Zone. Analyzing the seasonal variation from the precipitations to annual and monthly level you concludes that the stations possess a homogeneous hydrological regimen since so much the annual cycles as the precipitate magnitude they are similar.
