	In this ~~test case~~, the ground water table is initially the same as the water level in the waterway. Then, the level in the waterway suddenly rises with h0 meters. This causes water to infiltrate into the ground, slowly raising the ground water table as well.		In this [[Water Module benchmarks\|benchmark]], the ground water table is initially the same as the water level in the waterway. Then, the level in the waterway suddenly rises with h0 meters. This causes water to infiltrate into the ground, slowly raising the ground water table as well.
