East Dover Groundwater Flow Model

Project Contact(s)

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).

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

Date

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.

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

Project Contact(s)

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.

Development of a High Water Mark Database and Display System for Coastal Flooding Events in Delaware

Project Contact(s)

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).

Regional partners to focus on sea-level rise in Delaware

Date

A new partnership of scientists and federal officials from Delaware to Virginia will take a regional look at sea-level rise and how best to prepare for the impacts, including shoreline loss and increased flooding from storms.

A flood of innovation - UD and the state work together to mitigate coastal flooding in Delaware

Date

Two state agencies, the Delaware Emergency Management Agency (DEMA) and the Delaware Department of Natural Resources and Environmental Control (DNREC), collaborated with the University of Delaware and the Delaware Geological Survey (DGS) and found an answer in the Delaware Environmental Observing System (DEOS). DEOS was created in 2003 as a real-time, regional monitoring system that provides data on weather conditions, water levels, snow depth, and various other environmental factors obtained from automated weather stations in and around the state.
