Pump tests are procedures used to evaluate the performance and capacity of a well or pumping system. During a pump test, water is extracted from the well at a controlled rate, and measurements are taken to assess how the water level changes over time. This helps determine the well's yield and the sustainability of the water source. These tests are essential for various applications, including groundwater management, irrigation, and environmental assessments. By analyzing the data collected during the test, engineers and hydrologists can make informed decisions about water resource development and management.
