The Leaning Towers of Wilmington, Delaware: Emergency Response and Retrofit of the I-495 Viaduct to Address Lateral Squeeze
On a sunny, summer afternoon last June, the project manager for AECOM's open-end bridge design contract with the Delaware Department of Transportation (DelDOT) received an...
The Economics of Beach Nourishment in Delaware
This study provides a detailed examination of the benefits of Delaware's ongoing nourishment program, and examines the incidence of benefits to those who live within and outside of the...
A Statistical Approach to Modeling Groundwater Hydrology in a Constructed Wetland on the Atlantic Coastal Plain, Delaware
The design of wetlands based on groundwater as the principal source of hydrology pose uncertainties in areas where erratic seasonal groundwater fluctuations exist. Under these conditions,...
Ground Water
Protection Alternatives and Strategies in the U.S.A.
Prepared by the Task Committee on Ground Water Protection of the Water Resources Engineering Division of ASCE. This report presents general hydrogeologic...
State of Delaware-Scour Evaluation Program
The Delaware Department of Transportation (DelDOT) is evaluating the potential for scour at bridges which have a National Bridge Inventory (NBI)-Item 113 Code Rating of 6 (scour susceptible)....
Hydraulic Studies for a Large Wetland
Coastal wetlands are highly biologically productive and provide spawning and feeding habitats for many aquatic organisms. As has happened to freshwater wetlands, about half of the tidal...
Determination of Bridge Scour Velocity in an Estuary
Determination of the appropriate design for protection against bridge pier scour depends significantly upon the design velocities at the project site. In estuaries with large influences...
Modeling Climate Change Impacts on Water Resources
As part of the Electric Power Research Institute's (EPRI) comprehensive evaluation of the economic effects of climate change in the United States, we have developed methods...
Modeling the Impact of Uncertainty in Spatial Variability of Estuarine Boundary Conditions
Multi-dimensional numerical estuarine models that consider baroclinic forcing require the specification of both the water surface and the water density (salinity and temperature) at the...
Modeling the Impact of Sea Level Rise in Delaware Bay
A three-dimensional model of the Delaware Bay has been employed to provide insight on the impact of a 1.0 ft (0.304 in) sea level rise on salinity conditions in Delaware Bay. Model results...
Water Based Land Use Regulations Using GIS Water Budgeting Model
Protection of water quality and supplies in developing watersheds requires maintenance of the natural water budget. Water budgeting model using GIS provides foundation for land use regulatory...
Assessing the Impact of Channel Deepening in Delaware Bay Through Numerical Modeling
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Dredging Impacts on Delaware Estuary Tides
This study summarizes historic dredging activities and historic tidal trends in the Delaware Estuary. Since 1910, large-scale dredging and maintenance projects in the Delaware Estuary...
Validation of a Continental-Scale Storm Surge Model for the Coast of Delaware
Coastal structures are designed to provide protection against various forces of nature acting in the coastal zone. Structures such as seawalls are expected to provide onshore protection...
Applications of Large Domain Hydrodynamic Models to Generate Frequency-of-Occurrence Relationships
This paper describes theory and application of the Empirical Simulation Technique (EST), a statistical procedure for simulating time sequencing and frequency-of-occurrence relationships...
Water Policy and Management: Solving the Problems in Southern New Jersey
Southern New Jersey, which has relied solely on groundwater to satisfy its water supply needs, is depleting the primary source for that water. Symptoms of this depletion include declining...
Settlement Measurements of 50-ft High Embankments at the Chesapeake & Delaware Canal Bridge
This is a case history of instrumented settlement measurements on 49 to 56' (15-17 m) high bridge approach embankments of Delaware State Route 1 crossing of the Chesapeake & Delaware...
Design and Execution of Hydrodynamic Field Data Collection using Acoustic Doppler Current Profiling Equipment
Proposed major changes to the navigation channel depth in the Cape Fear River prompted an investigation of the existing hydrodynamics of the river system. The observed data are to be used...
Verification of a Three-Dimensional Model of Delaware Bay
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
