Delaware Coastal Inundation Maps

Coastal inundation map for the City of New Castle, DE

In early 2014, topographic LiDAR was collected for the entire state of Delaware through a collaboration between the USGS, Delaware Geological Survey (DGS), Department of Natural Resources and Environmental Control (DNREC), and Delaware Department of Transportation (DelDOT), funded through the Hurricane Sandy Supplemental Fund. The state-wide LiDAR data has a RMSEz of 6.3 cm in open terrain. From these data, a seamless, statewide 1-meter, hydro-flattened, bare earth digital elevation model (DEM) was produced. This topographic DEM was used to develop new bathtub-model coastal inundation maps for the state of Delaware. Inundation maps correspond to inundatation scenarios and include surfaces from Mean Higher-High Water (MHHW) to 7 feet above MHHW, in 1-foot increments. These maps will help assess the potential impacts of sea-level rise and advise long-range planning of infrastructure, facilities, land management, land use, and capital spending.

Coastal flood workshop - UD, organizations collaborate to improve Mid-Atlantic coastal resiliency

Sea-level rise, dissipating dunes and susceptibility to storm surges are a few of the factors that contribute to a vulnerable coast. A coast at risk means an increased potential for damage to coastal communities and ecosystems in the event of tropical systems, nor'easters or other damaging weather.

More than 40 experts representing state and federal agencies and regional universities gathered to discuss these and other important issues during the Coastal Flood Research, Modeling and Monitoring Workshop on Sept. 16.

John Callahan gave presentation at Army Reserve Forces Policy Committee annual meeting

John Callahan presented on several ongoing CEOE projects that focus on the monitoring of the tides and storm surge, such as from water level tide gages and satellite imagery, as well as on past data analysis and future forecasts. The presentation also included a live demonstration of the Delaware Coastal Flood Monitoring System. The operational and research-based projects are being jointly conducted by the Delaware Geological Survey, Delaware Sea Grant, the Delaware Environmental Observing System, the Delaware Environmental Monitoring and Analysis Center and the state Department of Natural Resources and Environmental Control Delaware Coastal Programs.

Determination of Future Sea-Level Rise Planning Scenarios and Development of Coastal Inundation Maps for the State of Delaware

The Delaware Geological Survey will review recent scientific literature and assessments of sea-level change in Delaware and identify appropriate scenarios to use for planning purposes throughout the state. This project will also develop new inundation maps along Delaware's coast that correspond to the identified scenarios.

U.S. Representative John Carney visits UD, CEOE

U.S. Rep. John Carney visited the University of Delaware’s Hugh R. Sharp Campus in Lewes to talk about the University’s ongoing coastal resiliency research and outreach in the College of Earth, Ocean, and Environment (CEOE) and administered programs as part of a weeklong climate change tour of Delaware.

Project Contact(s):

This project will study the water level behavior throughout the Delaware Inland Bays, with a focus on populated areas, during times of both storm and non-storm events through analysis of observational data from tide gages. It will also support the inclusion of the Delaware Inland Bays into the Delaware CFMS by developing a statistical relationships between the water levels along the Atlantic Ocean coast near the mouth of the Inland B

Analysis of Tides and Storm Surge from Observations Records in the Delaware Inland Bays

John Callahan, of the Delaware Geological Survey, presented a talk on "Analysis of Tides and Storm Surge from Observations Records in the Delaware Inland Bays", at the Coastal GeoTools conference (http://coastalgeotools.org/) in Charleston, SC, sponsored by NOAA and Association of State Floodplain Managers.
