The existing computer program for water-surface computation and delineation of the flood limit has been extended to include the effect of channel deformation during a flood. In the new program, the unsteady flow is approximated by successive temporal steady conditions; the change in channel boundary is corrected at each time step. This computer program has been applied to obtain the progressive changes of the channel boundary and water-surface profile during a flood as a result of erosion and sedimentation. By imposing an additional condition for the delta, another computer program has also been developed to compute the progressive growth of the delta of the river mouth and the variation of the delta stream pattern. /ASCE/
