Water Resources of the Lower Rio Grande De Manati Valley, Puerto Rico
From introduction: This report summarizes the results of the study in the Manati-Barceloneta area. The study includes an analysis of the availability of water from both surface and ground-water sources, and water quality. The major focus of the study was the alluvial valley of Rio Grande de Manati north of Highway 2. Areas outside of the valley were included as necessary only to the degree in which these influence the local hydrology.
Water Resources of the North Coast Limestone Area, Puerto Rico
From introduction: The North Coast Limestone area is one of the two most important ground-water provinces of Puerto Rico--the other being the South Coast Alluvial aquifer. The investigation of the water resources of the South Coast has progressed to the point that at this time (mid-1971) an electric-analog model of the area is being prepared. The hydrology of the North Coast Limestones, however, was never investigated as a whole before this investigation, and, therefore, this study was designed to assess the most important hydrolic features of the area.
