  • Patent number: 11107025
    Abstract: 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.

  • Publication number: 20180165616
    Abstract: The present invention relates to water events modeling including flood, the number one natural disaster in the world. Specifically, the present invention generates models of water events consist of one or multiple outputs from various modeling processes. It also generates analytics of water events, and integrating the water models for machine and human-eyes consumption. Further, the present invention produces derivatives, tools, and informational services for various purposes, such as, flood risk assessment; flood determination; and insurance rating. The present invention is the process and systems of producing one or multiple models of water events and derivatives, based on various inputs. For modeling water events at a given location and in a timely fashion, the present invention prepares, aggregates, integrates, and maintains all relevant inputs in one system.
