This lecture continues the previous discussion by focusing on common methods for conducting aquifer tests to determine transmissibility and storage coefficients. It outlines several hydrologic situations where these tests are applied, including scenarios with constant or variable discharge and different well orientations. Essential data collected during these tests includes well construction details, geological features, regional water level trends, and pumping rates. The lecture emphasizes the importance of systematic data collection, such as time-stamped water level observations and plotting drawdown on logarithmic paper. Additionally, it highlights the need to monitor water level recovery if initial pumping was irregular, to validate the accuracy of drawdown measurements.
