Influence Of Topographic Elevation Error On Modeled Storm Surge, Matthew Bilskie
Influence Of Topographic Elevation Error On Modeled Storm Surge, Matthew Bilskie
Electronic Theses and Dissertations
The following presents a method for determining topographic elevation error for overland unstructured finite element meshes derived from bare earth LiDAR for use in a shallow water equations model. This thesis investigates the development of an optimal interpolation method to produce minimal error for a given element size. In hydrodynamic studies, it is vital to represent the floodplain as accurately as possible since terrain is a critical factor that influences water flow. An essential step in the development of a coastal inundation model is processing and resampling dense bare earth LiDAR to a DEM and ultimately to the mesh nodes; …
