| Rainfall-Runoff-Inundation (RRI) Model simulates various hydrologic processes including rainfall-runoff, stream flow propagation and flood inundation in an integrated manner at a river basin scale. The model solves diffusive wave equationsapplied to flows on ground surface and subsurface on the two dimensional basis.The model is designed to be applicable even to large river basins with limited data by utilizing satellite-based information. The model application includes flood prediction and risk assessment, in particular at a basin with large floodplains. This technical manual describes the basic concept with equations, step-by-step model application and the advance use of the RRI model. |
