Introduction:
Pumping tests are critical methods for assessing the characteristics and behavior of aquifers, which are essential for understanding groundwater resources. These tests involve pumping water from a well at a controlled rate while monitoring the aquifer's response, including changes in water levels in nearby observation wells. The data gathered from these tests help hydrogeologists determine key aquifer properties such as transmissivity, storage coefficient, and hydraulic conductivity.
Pumping tests are fundamental in evaluating aquifers for water supply planning, environmental management, and assessing the long-term sustainability of groundwater resources. This Pumping Tests for Aquifer Evaluation course provides an in-depth understanding of these tests' methodologies, applications, and analysis techniques.
