Water is one of our most precious natural resources. Without it, there would be no life on earth. Hydrology has evolved as a science in response to the need to understand the complex water system of the earth and help solve water problems. Hydrologic data is needed for a variety of water studies. For example, in studies to assess the expected impacts of a waste-water treatment plant on the health of a river system, water samples are collected for laboratory analysis of various constituents.This edition 'Field Hydrogeology' brings together the most up-to-date research results and reviews and comprehensive guide to completing a hydrogeological study. Field methods, techniques and equipment used to study hydrologic systems including streams, riparian areas, hillslopes, and watersheds are explored. Field studies aimed at obtaining a three-dimensional understanding of groundwater systems are described. Its peer-reviewed research articles integrate subsurface hydrology and geology with associated disciplines, like as geochemistry, geophysics, geomorphology, geobiology, surface-water hydrology, tectonics, numerical modeling, economics, and sociology.Enriched with case studies and field research to aid understanding, and a specific emphasis on applied practical methods, this is a valuable guide for students taking courses and eager to research in Hydrogeology or field course session in Geology, Earth Sciences, Hydrogeology as well as researchers and practitioners.
