Hydrological study of a basin for the evaluation of the potential of a pico hydroelectric power station in a rural area

Abstract

The goal of the study was to estimate the average monthly runoff from a basin for the development of a pico hydropower in a rural-mountainous area of the jungle (Satipo) on Peru. Due to the lack of hydrometeorological data in hilly and remote basins in Peru, a hydrological estimate is essential to determine the hydroenergy potential in the study basin. First, the geomorphological parameters (shape and relief parameters) of the basin were determined and, subsequently, a precipitation analysis was made considering the data from 17 meteorological stations. To verify the homogeneity of the rainfall records, a consistency analysis was carried out using a double accumulation analysis. To estimate the flows of the study basin, in the absence of hydrometric information, the flow transposition method was used, in which the flows of the Ourohuari basin were transported. Likewise, it was verified that the geomorphological and hydrometeorological characteristics are similar, for this, a t-test was carried out for independent samples to verify the similarity in the annual precipitation between both basins. Finally, it can be concluded that the geomorphological characteristics and flow regular throughout the year in the Cashingari basin are favoring the development of a pico hydropower.
