Shallow water equations are widely used in inundation analysis and they are known to be successful in computation of floods over wide terrains. Flood propagation in between buildings in urban areas and flows around hydraulic structures such as bridges may not satisfy the assumptions of shallow flow and may display markedly more 3-Dimensional (3D) flow characteristics. However, for the convenience of fast numerical solutions, the shallow-current equations can also be used for such 3D flows and useful output may be obtained. In this study, shallow water equations are applied to flows with prominent 3D characteristics and results are evaluated. Water depths and velocity field in horizontal plane were calculated satisfactorily, surface waves in supercritical flow involving shocks were described in detail. However, it has been determined that the flow around several 3D obstacles increases by adding faults that calculate water depth. In case of uniform flows with boundary layer characteristics, velocity and bed shear stresses were predicted successfully using a suitable turbulence model.
