DGS Projects

Groundwater Resources of Sussex County (with an update for Kent County)

Project Contact(s):

This project is an integrated geologic/hydrologic study that will update our knowledge of the unconfined aquifers, confined aquifers, and groundwater resources of Sussex County. In addition, this project will utilize the results of recently completed study of the aquifer geology of Kent County (McLaughlin and Velez, 2005) to better define the groundwater resources of Kent County. The products to be produced by this study include aquifer depth and thickness maps and geologic cross sections for Sussex County. Products will also include a summary of basic hydrologic characteristics of aquifers in Kent and Sussex County and an analysis of water use for each aquifer.

Characterization of Tidal Wetland Inundation in the Murderkill River Estuary

Webbs Marsh, Murderkill River Estuary
Project Contact(s):

The project supports work by the Kent County Levy Court (Kent County) to evaluate the nutrient TMDLS for the tidal portion of the Murderkill River. The project will contribute to a more robust parameterization of river-marsh interaction in the water-quality model that is being developed for the Murderkill River by Kent County. The purpose of the project is to characterize the spatial and temporal inundation of a salt marsh in the Murderkill River Estuary and to determine the feasibility of using heat as a tracer of flow to characterize inundation of other marshes in the estuary.

Simulation of Groundwater Flow in Southern New Castle County, Delaware

Diagram of Conceptual Groundwater Flow Model
Project Contact(s):

To understand the effects of projected increased demands on ground water to supply water, a finite-difference, steady-state, nine-layer, groundwater flow model was used to simulate groundwater flow in the Coastal Plain sediments of southern New Castle County, Delaware. Results are published in DGS RI77
