Abstract

911 control centers wish to know the extent of flood given verbal eyewitness reports of depths at specific sites. First responders, given a flood extent map, might wish to know if a high-water vehicle can navigate a specific route. Before an event, FEMA needs accurate elevations in for issuing FIRMs (Flood Insurance Rate Maps). Many of these needs can be addressed via prior-collected data from a ranging sensor, LiDAR, in which an increasing number of municipalities are investing.

Working with organizations such as regional council of governments, FEMA, and the Army Corps of Engineers, we are integrating LiDAR with other data sources to obtain data products of higher value and accuracy. Specifically, we are determining terrain and building structure properties that lead to a better understanding of the potential risks of wind and flood damage as well as provide post-event assessment. This entails solving several problems in both the science domain and the application domain. In the application domain there are issues relevant to determining accurate breaklines, accurate roof topologies, and building heights and footprints. We address all of these.

GIS techniques for creating river terrain models for hydrodynamic modeling and flood inundation mapping

Two- and three-dimensional (2D/3D) hydrodynamic models require the geometric description of river bathymetry and its surrounding area as a continuous surface. These surface representations of river systems are also required in mapping flood inundation ...

Flooding is a complex process affected by many factors in which the flood discharge characteristics and the topography of the inundated region are of great importance. This study aimed at the development of a manageable method for flood inundation ...
