Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
Preliminary Results of Direct Tension Tests on First-Year Sea Ice Samples
We present the initial results of our tests to determine the tensile behavior of columnar sea ice over a range of temperatures extending from -20 to -3?C and strain rates of 10-5...
New Hydrologic Instrumentation in the U.S. Geological Survey
New water-level sensing and recording instrumentation is being used by the U.S. Geological Survey for monitoring water levels, stream velocities, and water-quality characteristics. Several...
Trouble on the Waterways?
Crumbling highways and bridges can cripple the U.S. economy. A lesser known transportation problem is the condition of our inland waterway system. Waterways are a cost-efficient, environmentally-sound...
Mineralogic Alteration History and Paleohydrology at Yucca Mountain, Nevada
The importance of paleohydrology to the Yucca Mountain Site Characterization Project derives from the role water will play in radioactive-waste repository performance. Changes in hydrologic...
An Alternative Method to Mariotte Reservoir System for Maintaining Constant Hydraulic Pressure
Several problems with the Mariotte reservoir system were discovered when it was used to apply a constant water pressure as a boundary condition for a prolonged period. The constant-pressure...
Basin Management Plan for the Pajaro Valley, Central Coast of California
The Pajaro Valley, a coastal basin located along California's Central Coast, is primarily an agricultural valley with over 90 percent of its water supplied from local groundwater...
Management of Subsidence in an Urban Environment
Houston, Texas is the fourth largest city in the United States and with its metropolitan area included, comprises a population of almost four million people. Large quantities of groundwater...
A Comparison of Two Large Scale NLP Strategies for Determining Optimal Pump Station Controls
To solve the general nonlinear problem which is not simplified using the uniform spatial demand patterns, a two-level hierarchial scheme has been identified. The purpose of this decomposition...
A Particle Beam Simulation
A two-dimensional beam simulation is developed in which the beam is composed of uniform rectangular blocks. Internal forces in the beam are caused by relative motion between adjoining...
Performance of Building Resistance to Water, Waves and Erosion
Water damage to buildings due to Hugo was widespread and severe throughout low-lying coastal areas. Flood insurance claim payments have already exceeded $350 million, the largest payout...
CZMA Consistency Opinions: An Undiscovered Body of Law
The Coastal Zone Management Act allows states to block the issuance of Federal licenses and permits if the permitted activity would be inconsistent with the state's Federally...
Induced Subsidence: Environmental and Legal Implications
Subsidence of coastal areas can be induced by withdrawal of fluids from shallow, unconsolidated horizons beneath the shore zone. In southern California, Huntington Beach, Torrance/Redondo...
Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...
Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...
Sea Water Environmental Remote Sensing Application on Daya Bay Nuclear Power Station
Owing to its extensive and complete characterization, remote sensing investigations have a special ability to analyze seawater environments and to monitor pollution at coastal nuclear...
Increased Attention to Ocean and Coastal Protection Legislation in the 101st Congress
For all the grumbling about the ineffectiveness of Congress, the 101st Congress produced a surprising number of critical pieces of coastal- and ocean-related legislation, and began the...
Environmental Impact Assessment and the Conservation of Marine Biological Diversity
Legislation is pending to include assessment of biodiversity in the Environmental Impact Statement process and revise the National Environmental Policy Act to better address the conservation...
Golf Course Development Concerns in Coastal Zone Management
The rapid growth of golf course development in South Carolina's coastal zone presents new challenges in protecting coastal water and wetlands. While filling or dredging of...
The States/British Columbia Oil Spill Task Force
The States/British Columbia Oil Spill Task Force, consisting of government representatives from Washington, British Columbia, Alaska, Oregon, and California, formed in 1989 in response...
