Utility Programs for DWOPER and DAMBRK
Time and computer resources greatly limit potential investigations and sensitivity anslyses. In order to facilitate modeling with the National Weather Service (NWS) programs DWOPER (Operational...
A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...
Flood Hydrology Modeling: U.S. Virgin Islands
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...
Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...
