Coordinating Toxic Cleanup with Future Site Utilization
The Port of Olympia owns a site where former industrial activity left a legacy of toxic contamination, and which is currently involved in a cleanup action. A waterfront site which was...
Selection of Superior Planting Stocks and Development of Regeneration Techniques for Coastal Restoration: A Pilot Study
There is an increasing demand in the U.S. for wetland plants to be used for marsh restoration and coastal stability projects. However, physiologically adapted wetland plants suitable for...
Bioaccumulation in Mussels Caged in Alamitos Bay, CA
Alamitos Bay is a coastal embayment located in the southern portion of the highly urbanized Los Angeles basin. There is concern of the potential for contamination stemming from urban non-point...
The NS&T National Benthic Surveillance Project: Contaminants in Fish Tissues
The National Benthic Surveillance Project, part of NOAA's National Status and Trends (NS&T) Program, has been regularly measuring more than 70 contaminants in liver tissue of selected...
Slides and Slumps on the Coastal Zone Between San Miguel and El Descanso, Baja California, Mexico
The coastline between Tijuana and Ensenada is being subject to intensive development, mainly as resort property, and because of the roughness of the adjacent areas inland, the coastal...
Aquatic Disposal of Dredged Material in the Belgian Part of the North Sea
Extensive research and study on the behaviour of dredged material after dumping in the sea has been conducted on the disposal grounds S1 S2 and Zb Oost located in the southern Bight of...
Utilization of the Coastal Areas for Aquaculture in Nigeria
The current domestic fish production in Nigeria is estimated to be 363,706 tonnes whereas the projected demand is 1,237,000 tonnes. This leaves a deficit in demand of 874,294 tonnes which...
Environmental Impacts of Human Activities on the Coastal Areas of Nigeria
Nigeria has a coastline of approximately 800 km and the coastal areas support a myriad of economic activities as well as a large population. This paper reviews the geology, geomorphology,...
Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...
Infiltration in Two Sand Dune Areas in Saudi Arabia
Field infiltration experiments at several locations in two sand dune areas in Saudi Arabia were conducted. Results of these field tests are compared with predictions of the Green and Ampt...
The Use of Residence Time to Describe a Hillslope
Queueing theory has been applied to the determination of Soil Water Residence Time (SWRT) using an 18 year data set. The calculated SWRTs agree qualitatively with the lags exhibited by...
Modeling Two-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals
A two-dimensional model to simulate the subsurface flow, microbial growth-degradation, and transport and biodegradation of chemicals in groundwater environments (2DFATMIC) is developed....
National Weather Service Operational River Forecasting in a UNIX Environment
The mission of the National Weather Service (NWS) includes providing river and flood forecasts and warnings for protection of life and property, and providing basic hydrologic forecast...
In-Situ Bioremediation Using a Recirculation Well
An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use...
Sacramento Drainage Manual?Hydrologic Procedures
For a period of over two years, HDR Engineering, Inc. (HDR) and HYDMET have been working with the City and County of Sacramento to develop a Drainage Manual. This Manual contains seven...
Sacramento Hydrologic Procedures Interim Adoption
In November 1989, the County and City of Sacramento jointly undertook the development of a manual for the design of drainage and flood control facilities in the region. Significant technical...
Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
Primary Metals and Criteria for Water use in the Columbia River, British Columbia
We assessed primarily concentrations of lead, cadmium, copper, zinc and water hardness in the Columbia River between Birchbank and Waneta. Water quality in this reach of the river is affected...
Electro-Osmotic Removal of Nitrates from Soils
Nitrate migration to ground and surface waters is a serious U.S. contamination threat. Electro-osmosis may be a more effective means for soil reclamation than leaching or chemical treatment....
Subsurface Drip Irrigation Can Reduce Pollution
Several researchers have indicated that precise subsurface drip (SSD) application of irrigation water can be effectively used to reduce pollution of the aquifer when irrigating with reclaimed...
