Coastal Changes and Impacts

Scientific Research

Many applications of geospatial data in coastal environments require detailed knowledge of near-shore topography and bathymetry as physical processes in the coastal environments are controlled by both onshore and offshore geomorphology. Integrating disparate light detection and ranging (lidar) elevation data and bathymetric data sources into a common topobathymetric database is important for numerous science applications, such as shoreline delineation, coastal inundation mapping, sediment transport, sea-level rise and storm surge models, and tsunami impact assessments. An integrated topobathymetric database is also valuable for analyzing the impacts of various climate change scenarios on coastal regions, assessing geomorphic change, monitoring critical topographic features such as, levees, seawalls and embankments, and accurate mapping of wetland elevations.
