METHOD AND SYSTEM FOR GENERATING A FLASH FLOOD RISK SCORE
Computer-based systems and methods are disclosed for modeling and predicting flash flood risks for real estate properties. In some embodiments, the systems and methods can predict flash flood risks for real estate properties by considering a variety of factors, including watershed hydrology characteristics, land surface characteristics, meteorological characteristics, and/or property characteristics. In some embodiments, the systems and methods can improve determination of investment metrics or automated valuations by considering flash flood risks in determining the investment metrics or automated valuations.

determine a flow accumulation associated with the property based at least in part on the determined flow direction associated with the property;
generate a flash flood risk model based at least in part on the determined flow accumulation associated with the property;
calculate a flash flood risk score by applying the flash flood risk model to the property; and
store the calculated flash flood risk score in a data repository.
