Sommario/riassunto: | Water Wells and Boreholes provides the necessary scientific background together with practical advice using global case studies, in an accessible easy to use style suitable for both postgraduates/researchers and practitioners. The book begins with an introduction to the type and uses of water wells from water supply and irrigation through to groundwater remediation. It then covers well siting detailing how to source data from geophysical surveys, remote sensing etc. Well design is then summarised to ensure the well is stable and cost-effective. The book ends with three chapters coveri |
