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.
In 2015, DGS became aware of a situation east of Dover where there is potential for overpumping of the Columbia aquifer by the City of Dover’s Long Point Road wellfield (LPRW) and numerous large-capacity irrigation wells in the surrounding area (Figure 1).
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.
DGS is building a database and web distribution system to collect, manage, and display high water marks (HWMs) that are observed throughout Delaware as a result of flooding events. Historical peak water levels can be extracted for past storms or for a selected geographic area. Development is being done in partnership with the Office of the Delaware State Climatologist, the Delaware Environmental Observing System (DEOS) and the Delaware Environmental Monitoring and Analysis Center (DEMAC).
