Sample Questions

Question 1
According to Darcy's Law (Darcy-Gesetz), what is the fundamental mathematical relationship governing laminar groundwater filtration flow through a saturated porous aquifer?
Q = k_f * I * A, where Q is discharge, k_f is the hydraulic conductivity coefficient, I is the hydraulic gradient (dh/L), and A is the cross-sectional flow area.
Q = k_f * (I^2) * A, where discharge increases quadratically with the hydraulic gradient regardless of flow velocity.
Q = (k_f * A) / I, where discharge is inversely proportional to the hydraulic gradient across the aquifer cross-section.
Q = sqrt(k_f * I) * A, representing turbulent velocity dispersion through cohesive clay layers.
Question 2
What is the defining hydrogeological difference between an unconfined aquifer (ungespannter Grundwasserleiter) and a confined aquifer (gespannter Grundwasserleiter)?
An unconfined aquifer is bounded above by an impermeable rock layer, while a confined aquifer is open directly to atmospheric precipitation.
An unconfined aquifer has a free water table at atmospheric pressure (phreatic surface), whereas a confined aquifer is overlain by an impermeable confining bed (Aquitard/Grundwassernichtleiter) causing its piezometric surface (Druckspiegel) to rise above the aquifer roof.
An unconfined aquifer contains exclusively artesian groundwater that overflows the ground surface, whereas a confined aquifer contains only stagnant vadose water.
An unconfined aquifer has a hydraulic conductivity of zero, whereas a confined aquifer has infinite transmissivity.
Question 3
A gravel aquifer has a hydraulic conductivity of k_f = 2.5 * 10^-3 m/s, a flow cross-section of A = 40 m², and a hydraulic gradient of I = 0.004. What is the total groundwater discharge (Q) passing through this cross-section per hour?
0.144 m³/h
14.4 m³/h
1.44 m³/h
144.0 m³/h
Question 4
What are the core simplifying assumptions formulated by Dupuit (Dupuit-Annahmen) used to derive the steady-state well drawdown equation for unconfined aquifers?
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.
Question 5
For a fully penetrating well in a confined aquifer with thickness M = 8.0 m, hydraulic conductivity k_f = 1.0 * 10^-3 m/s, drawdown s_w = (H - h_w) = 3.0 m, radius of influence R = 150 m, and well radius r_w = 0.30 m, what is the steady-state discharge Q calculated via the Dupuit-Thiem formula?
Approx. 24.3 l/s (87.4 m³/h)
Approx. 7.2 l/s (26 m³/h)
Approx. 76.5 l/s (275 m³/h)
Approx. 150.0 l/s (540 m³/h)
