The present invention generates multiple models of water events based on various modeling processes input data. It can generate analytics of water events and integrating water models for displays. The present invention further produces derivatives, tools, and informational services for flood risk assessment; flood determination; and insurance rating. The present invention integrates and maintains all relevant inputs in one system for modeling water events at a given location in a timely fashion. The input datasets include water events' extent, flooded areas, floodplain, inundated areas and measurement of water condition. The datasets may include other data, such as, terrain elevation data, land use land cover data, soil conductivity, water gauge measurements and hydrologic regression equations for calculating flows. Other inputs may also include hydrologic modeling algorithms, hydraulic modeling algorithms, geospatial algorithms, and local or remote data of real-time water conditions acquired through machine services.
