Abstract :
Because of influence of drastic human activities, flow routing methods of river that neglected seepage loss in flood forecasting exhibits a strongly inadaptability based on principle of mass conservation, continuity equations of water body considering seepage loss are derived in five conditions from simple one to difficult one, which joined with dynamic equation composed de Saint-Venant system of equations that considered infiltration term, the flow routing inverse problem of river considering seepage was proposed and an optimization model that equivalent in the inverse problem was presented, which lays a foundation in accurately estimating infiltration capacity of flow routing model of river or river network.
