Preliminary Characterization of the Hydrodynamic of Karstic Aquifer in the “Promontorio de Cabrera”, Province of Maria Trinidad Sánchez, Dominican Republic

Abstract

The “Promontorio de Cabrera” is represented by a mountainous massif of 250km², with elevations of more than 400m of height, distributed to 6km from the coastline, and conformed by karstic limestone rocks. There is an aquifer with conical structure and radial flow that responds to the morphological regional patterns, and where the groundwater has depths of 200m in the central sector of the massif and of 80m in the borders. The aquifer structure has a better component developed in NW, N and NE, where the groundwater appears in karstic springs, which have altitude of 120 and 180m and flow to the sea. Other springs in the NNE sector of the massif are distributed to heights of 280m. In the S and SE of the massif, the karstic springs are distributed to heights of 120 and 150m, and the flow is to the local river and wetlands. Other two springs, in the level of 260m, suggest its hydrogeology relationship with the morphological structure. A shallow aquifer associated with the system of karstic summits has been characterized, where the waters appear in karstic springs and flow to basins and infiltrate for karstics drains.
