Ground-Water Resources Reconnaissance of the Yap Main Islands, Federated States of Micronesia.

摘要

The report describes the geohydrologic framework of the Yap main islands, and discusses the drilling of exploratory wells to evaluate the potential for increasing ground-water development. Field investigations were made of the geology and the water-supply systems on the islands of Yap, Gagil-Tamil, Maap, and Rumung. Included in the effort were water balance calculations to estimate ground-water recharge, hydrologic monitoring at wells and streams, and compiling of rainfall, pan evaporation, and water-quality data that have been recorded since the publication of a water-resource summary of the Yap main islands by the U.S. Geological Survey.
