Test
problem 1: Tidal oscillations in a flat-bottom circular basin
Conditions:
Linear, 2-D, no friction, shallow water
R (radius) = 50 km
Forcing:
M2 tidal elevation at the open boundary
Case 1: Normal oscillation
H= 10 m, M2 tidal
elevation at OB = 1 m
Open boundary
Case 2: Near-resonance oscillation
H= 1 m, M2 tidal
elevation at OB = 1 mm
