CARACTERIZACIÓN DE ACUÍFEROS EN EL ÁREA DE LA PRESA DEL PROYECTO HIDROELÉCTRICO ANGOSTURA, TURRIALBA, COSTA RICA

Abstract

n this paper has been investigated the geometrical and hydraulical features of the main aquifersin the dam area of the Angostura Hydroelectrical Project. The boreholes indicate the subsurface is made up tothe depth of 80 m of a sequence of low permeable and high permeable layers, where the last once are the mainaquifers. The aquifers are various in extension and thickness. There are four aquifers, but three aquifers are confined which are influencing through the structures of the dam side. This study is the first attempt to create a conceptual model of the groundwater behavior of aquifer system in the dam area and it can supports future investigations with the mathematic simulation of pumping well group.
