Befähigungsprüfung Brunnenmeister Practice Questions - Befähigungsprüfung Brunnenmeister (Austria) Exam

Flow velocity is assumed strictly vertical, streamlines are parabolic, and hydraulic gradient equals the cosine of the phreatic slope. The well screen is assumed completely impervious, forcing all groundwater to enter exclusively through the open bottom sump. Groundwater flow is assumed fully turbulent throughout the entire cone of depression, and aquifer compressibility dominates over gravity drainage. Flow lines are assumed horizontal, equipotential surfaces are vertical cylinders concentric to the well, and the hydraulic gradient equals the slope of the free water table (dh/dr) across the entire saturated thickness.
