This lecture explores the behaviour of drawdowns around discharging wells, where water levels drop and create contours that are typically elliptical but can be circular in homogeneous aquifers. In unconfined aquifers, these contours represent the top of cylindrical sections whose cross-sectional area decreases towards the well, necessitating a higher hydraulic gradient to maintain flow. The water table near a discharging well forms an inverted cone and the drawdown can be described using Darcy's law in polar coordinates. The lecture introduces the Thiem equation, which relates the head difference to the logarithm of radial distance, demonstrating that the head decreases logarithmically with distance from the well. Practical examples illustrate how these calculations can predict drawdowns at various distances, emphasizing the consistency of drawdown intervals on semi-logarithmic graphs.
