Opis

The over-exploitation of groundwater and marked changes in climate over recent decades has led to unacceptable declines in groundwater resources. Under the likely scarcity of available water resources in the near future, it is critical to quantify and manage the available water resources. With increasing demand for potable water for human consumption, agriculture, and industrial uses, the need to evaluate the groundwater development, management, and productivity of aquifers also increases. Laboratory Manual for Groundwater, Wells, and Pumps serves as a valuable resource and provides a multi-disciplinary overview for academics, administrators, scientists, policymakers, and professionals involved in managing sustainable groundwater development programs. It includes practical guidance on the measurement of groundwater flow, soil properties, aquifer properties, wells and their design, as well as the latest state-of-the-art information on pumps and their testing, and groundwater modeling.

Features:

• Covers basics of groundwater engineering, advanced methodologies, and their applications and groundwater modeling

• Examines groundwater exploration, planning and designing, and methods for formulating strategies for sustainable management and development

• Serves as a reference for practitioners on practical applications and frequently occurring issues of groundwater investigations, development, and management.
