Provide measurements over various geographic areas in a 11,000 square mile region. Provide an accurate short term forecast of rainfall intensity in a real-time mode. These areas can be overlapping such that rainfall can be simultaneously calculated for each of the County's Service Basins, each Component Agency area and each RDII mini-basin established for this study. They are one of the basic quantitative tools which hydrologists use to characterize a rain event. The user can select the basin and the time period.
Maps can be over the entire study area or zoomed to individual hydrologic basins.
Several viewing formats are available. This gives an excellent general overview of the storm and an overview of the next hour's forecast rainfall pattern. When viewing the rainfall forecast map, the system displays the confidence level of the forecast. The user can switch to a more localized view and watch the storm's passage over the study area. I problems can be identifying where sewage flow backs up in the sewer system, resulting in environmental or public health concerns.
