LARSIM

LARSIM is an acronym for Large Area Runoff Simulation Model. It is a hydrologic model, which describes continuous runoff processes in catchments and river networks. LARSIMis based on an earlier river basin model for single flood and low-flow episodes, from which it inherited the general model structure. Hydrological processes are simulated in a series of subarea elements connected by flood routing elements in a predetermined sequence. LARSIM simulates the hydrologic processes for one element for a defined time period. The resulting output hydrograph is the input information for the next element according to the general model structure rules. The model structure can be grid based or based on hydrologic subcatchments... Since about a decade hydrological system data (e.g. land use, soil types, topography and channel data) needed for model input is digitally available for large areas in a high spatial resolution. At the same time computer speed and capacity have evolved significantly...
