Abstract: A method for evaluating risks associated with flooding in a geographical region comprises the steps of defining the region, dividing the region into a plurality of grid cells, identifying data relating to characteristics of the region within the cells, determining a probability of occurrence of a flood related event in a selected grid cell using the identified data, and determining an insurance premium for the risk. Certain embodiments are implemented using a computer, and involve reference to an alternative source of information regarding the occurrence of flood-related events in a geographical region. In one embodiment, a model is developed and calibrated by reference to data from a first geographic region, and subsequently used to determine the probability of occurrence of a flood event in a second region.
