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.
DGS welcomes James D. Hanes to UD NEWRNet project
Environmental Sciences student James Hanes (BS 2016) has accepted a Water Resources Center Undergraduate Internship for Fall 2015 to work with A. Scott Andres of DGS, and William Ullman and Christopher Main of the School of Marine Science and Policy at the University of Delaware. James will work on high-frequency environmental data collected by the North East Water Resources Network (NEWRNet) project (http://www.dgs.udel.edu/projects/newrnet-north-east-water-resources-net…), an NSF-EPSCoR funded project that includes investigators and students from the Universities of Delaware, Rhode Island, and Vermont.
Delaware Geological Survey issues report on groundwater modeling in eastern Sussex County
The Delaware Geological Survey (DGS) has released a new technical report titled Simulation of Groundwater Flow and Contaminant Transport in Eastern Sussex County, Delaware with Emphasis on Impacts of Spray Irrigation of Treated Wastewater, which was prepared by Changming He and A. Scott Andres of DGS.
DGS Report of Investigations No. 79 documents development of a detailed study of subsurface hydrogeology, interactions between aquifers and streams, and the effects of spray irrigation of treated wastewater on groundwater beneath southern eastern Sussex County.
RI79 Simulation of Groundwater Flow and Contaminant Transport in Eastern Sussex County, Delaware With Emphasis on Impacts of Spray Irrigation of Treated Wastewater
This report presents a conceptual model of groundwater flow and the effects of nitrate (NO3-) loading and transport on shallow groundwater quality in a portion of the Indian River watershed, eastern Sussex County, Delaware. Three-dimensional, numerical simulations of groundwater flow, particle tracking, and contaminant transport were constructed and tested against data collected in previous hydrogeological and water-quality studies.
Drought Conditions Indicators for Delaware
The DGS will research past performance of the Water Conditions Index (WCI) for Northern New Castle County, as compared with other established drought indicators, and investigate modifying the WCI, if needed. We will also investigate the feasibility of quantifying water conditions in Kent and Sussex Counties by analyzing factors that are most important to these regions (i.e., precipitation, groundwater for agricultural irrigation, etc….)
