The Weathering of Spilled Crude Oil in Coastal Water Environment
A research project was conducted at the Technical Research Centre of Finland (VTT) in order to study the long-term behaviour of spilled crude oil in the brackish water under cold and icy...
Environmental and Economic Feasibility of Water Supply Alternatives in Hawaii and California: Desalination, Water Marketing and Conservation
Increasing urban demand for potable water in Honolulu, Hawaii and Santa Barbara, California, jeopardizes scarce supplies. The objective of this analysis is to compare the costs and benefits...
Shell Island Evolution
In 1979, Shell Island was overtopped by Hurricane Bob breaching the barrier island with an opening that now has increased to a width of approximately 2.7 kilometers. Saltwater intrusion...
Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...
Numerical Simulation of Alabama's Weeks Bay Estuary
Weeks Bay system models describing water elevation, water circulation, salinity and BOD/DO concentrations are used to investigate two case study scenarios - a dredged ten foot deep boat...
Resilience of Seacoast Bluestem Barrier Island Communities
Natural disturbance is an important force in population and community dynamics and barrier islands are paradigms of disturbance dominated ecosystems. They are formed, shaped, and moved...
Mechanics of Cohesionless Sediment Transport in Coastal Waters
Conceptual mechanics-based models for sediment transport processes in steady and unsteady turbulent boundary layer flows are derived and discussed. To the extent possible the predictions...
Short-Term Characteristics of Coastal Lagoon Entrances in California
Methods of predicting the frequency of lagoon opening conditions and the cross-sectional area of the inlet channel are reviewed. The potential variation from these empirical relations...
Eustatic and Neotectonic Controls on Salt Marsh Sedimentation
This paper presents a revised conceptual model of the long-term evolution of back-barrier marshes on the macro-tidal north Norfolk coast and their adjustment to tidal levels. The present...
Salinity Problems Associated with Reuse Water Irrigation on Southwestern Golf Courses
One of the most severe of the potential reuse water quality problems is salinity. While many water supplies in the southwest have relatively high total dissolved solids (TDS) concentrations,...
Effect on Soil and Groundwater Due to Long-Term Land Treatment
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....
High Saline Water-Table Effect on Wheat Irrigation
Hydraulic, weighing lysimeters were used for five years to measure the effect of high, saline water tables on irrigation requirement of wheat. Each year the wheat was grown with no water...
Water and Salt Movement Under Trickle Irrigation
Experiments have been conducted to study the effect of the drip irrigation parameters on the movement of water and salt in the trickle wetted soil volume. The study indicated that for...
Agricultural Drainage Reuse in Agroforestry Systems
On the westside of California's San Joaquin Valley, agroforestry systems are being evaluated as a solution to the agricultural drainage problem. Eucalyptus tree plantations...
Flexible Irrigation Supply Pilot Projects?Part II: Sri Lanka, Pakistan, India, Egypt
The Sri Lanka project covers about 150 one hectare farms on the lower half of a unit served by one distributary. The upper part, because of delays in construction, was left as an earth...
Use of Stable Isotopes, Tritium, Soluble Salts, and Redox-Sensitive Elements to Distinguish Ground Water from Irrigation Water in the Salton Sea Basin
Evaporative concentration of irrigation water diverted from the Colorado River to the Salton Sea basin for several decades has produced an overlying system (that includes drainwater and...
Transportation of Cities' Colorado River Water in the Salt River Project's Canal System
Cities in the Phoenix, Arizona, metropolitan area have contracted with the Central Arizona Water Conservation District to take delivery of Colorado River water. Many of their water treatment...
Effects of Wastewater Irrigation on Aqueous Geochemistry
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....
On the Application of Multiphase Flow Models for the Simulation of Density Stratified Flow in Aquifers
Two types of numerical simulation approach are usually applied when simulating density-stratified flow in aquifers: (a) the sharp interface approach, and (b) the coupling of flow transport...
Concentration Measurements in Dense Leachate Plumes Using a Gamma Radiation System
An automated, nonintrusive technique is discussed that determines salt concentrations in dense leachate plumes. The dense plumes were introduced from a line source into a relatively narrow...
