Cell size convergence is an important concept in flood modelling. 


This test is designed to simulate flood wave propagation down a river valley following the failure of a dam. The valley DEM is ~0.8 km by ~17 km and the valley slopes downstream on a slope of ~0.01 in its upper region, easing to ~0.001 at lower elevations. <br>

The inflow hydrograph shown below is applied as a boundary condition at the upstream end of the valley. <br>
