Flexural steel anchorage performance at diagonal crack locations

Creator:: Triska, Mary Ann
Abstract:: Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

Creator:: Herrmann, Joan F.
Abstract:: Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

Experimental evaluation and chemical modeling of hexavalent chromium adsorption, desorption, and reduction in a natural soil

Creator:: Azizian, Mohammed F.
Abstract:: Chromium and its compounds are widely used by modern industries, resulting in large quantities of this element being discharged into the environment. To remove chromium from contaminated soils and ground water, it is necessary to predict chemical and physical processes that control the rate of reactions and transport of chromium...

Tidal range changes in the Delaware Bay : past conditions and future scenarios

Creator:: Hall, George F.
Abstract:: Throughout the Holocene, appreciable changes in bathymetry are hypothesized to have resulted in large changes to tidal datums in coastal and estuarine areas. An understanding of tidal change is an important contribution to the knowledge of relative historical sea-level change and future coastal planning. To test this hypothesis, the Advanced...

Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

Creator:: Parker, Kai A.
Abstract:: Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

An evaluation of the cubic autotape under dynamic conditions

Creator:: Plasker, James Robert
Abstract:: Accuracy requirements for positioning a vessel in the near shore area have increased in recent years. To meet these requirements several electronic positioning systems have been developed. One such system is the Cubic Autotape Model DM-40. The Autotape is a circular positioning system which utilizes the phase comparison between transmitted...

Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

Creator:: Cheng, Tiffany Kay
Abstract:: Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

Creator:: Kalmbacher, Kirk D.
Abstract:: The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...
