Abstract:

To develop a consistent basis for evaluating existing flooding problems and for planning activities to reduce future flood damage, a watershed modeling project was initiated by the Government of the U. S. Virgin Islands in 1979. This paper summarizes the procedures utilized to model flood hydrology in the U. S. Virgin Islands, presents results of hydrograph analysis performed using observed streamflow data, and concludes by briefly summarizing the status of watershed modeling performed to date. Flood hydrographs were developed for 10-, 25-, 50-, and 100-year design storm conditions using the HYMO computer program. Thirteen major watersheds in the Islands were evaluated using HYMO, and conceptual solutions to flooding problems were developed.
