Hydrologic Modeling of Extreme Floods Using Remote Sensing Observations

Abstract

The objectives of this research are to develop a comprehensive understanding of extreme floods and to dramatically improve the capability to model these events. Paired diagnostic and modeling studies play a central role in this project. Hydrologic and hydrometeorological studies of extreme floods in the Great Plains, central Appalachians, The Milwaukee metropolitan area, Charlotte, NC metropolitan area and, high-gradient rainforest west of Puerto Rico have been completed. For the large flood events examined in this study, the spatial (1 km) and temporal (15 minutes) resolution of rainfall estimates provided by the WSR-88D was crucial to accurate modeling of extreme flood response. Coupled hydraulic and hydrologic modeling studies using RMA-2V and the Network Model have been carried out to characterize the dependence of flood response on floodwave attenuation and altered runoff processes associated with impervious cover and elaboration of the drainage network.
