Coastal Changes and Impacts
Home
Climate change is a significant factor that affects both the natural and human components of the coastal landscape. Therefore, assessments and monitoring of vulnerable coastal lands are needed in locations where an ever-increasing population lives in communities at risk from sea-level rise, inundation, and storm surge.

The objective of the U.S. Geological Survey Coastal Changes and Impacts focus area at the Earth Resources Observation and Science Center is to conduct research and applications to assess the interactions between human inhabitants, natural features, and environmental conditions in coastal landscapes. This work focuses on the geographic nature of coastal changes through use of high- resolution, high-accuracy imagery and elevation data that are critical for mapping sea-level rise, flood hazard and inundation, and for characterizing storm surge dynamics.

Depth calibration and validation of the Experimental Advanced Airborne Research Lidar, EAARL-B
The original National Aeronautics and Space Administration (NASA) Experimental Advanced Airborne Research Lidar (EAARL), was extensively modified to increase the spatial sampling density and improve performance in water ranging from 3–44 m. The new (EAARL-B) sensor features a 300% increase in spatial density, which was achieved by optically...
Wright, C. Wayne; Kranenburg, Christine; Battista, Timothy A.; Parrish, Christopher Introduction: Special issue on advances in topobathymetric mapping, models, and applications
Detailed knowledge of near-shore topography and bathymetry is required for many geospatial data applications in the coastal environment. New data sources and processing methods are facilitating development of seamless, regional-scale topobathymetric digital elevation models. These elevation models integrate disparate multi-sensor, multi-temporal...
Gesch, Dean B.; Brock, John; Parrish, Christopher E.; Rogers, Jeffrey N.; Wright, C. Wayne Hydrologic connectivity: Quantitative assessments of hydrologic-enforced drainage structures in an elevation model
Elevation data derived from light detection and ranging present challenges for hydrologic modeling as the elevation surface includes bridge decks and elevated road features overlaying culvert drainage structures. In reality, water is carried through these structures; however, in the elevation surface these features impede modeled overland surface...
