The Colorado River Salinity Program?An Overall Perspective
Economic losses resulting from increases in salinity in the Colorado River system were estimated to be $311 million annually in 1986. As a result of protests by Mexico to the United States...

The USDA Colorado River Salinity Control Program
Approximately 37 percent of the salt contribution in the Colorado River can be attributed to irrigation activities in the river basin. The United States Department of Agriculture (USDA),...

Blending Saline and Non-Saline Waters Reduces Water Usable for Crop Production
The purpose of this paper is to provide theoretical and conceptual evidence to show that water quality protection programs which dispose of agricultural drainage waters through blending...

Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...

Fouling and Wood-Boring Communities Distribution on the Coast of Rio De Janeiro
The paper reports on a study of the dynamics of fouling communities and the distribution of wood-boring organisms along the coast of Rio de Janeiro, Brazil, which was motivated by the...

Effects of Salts on Soils and Plants
Salinity is a major constraint to crop production in many irrigated lands of the world. Management practices are needed for the control of soil and water salinity. The development of appropriate...

Root Zone Salinity Control?Leaching Fraction, Spatial Variability
This paper gives an overview of three chapters that are contained in a new ASCE manual called Agricultural Salinity Assessment and Management Manual. Chapter 9 is entitled Field Sampling...

Land Drainage and Estuarine Salinity Response
An investigation is being conducted to (1) quantify the short-term effects of freshwater agricultural drainage on salinity in a tidal creek and (2) evaluate the off-site effects of water-control...

Case Study in the Rehabilitation of a Pumped/Storage Installation - Salina Powerhouse Grand River Dam Authority
This paper presents a specific case study in the rehabilitation of a pump/turbine for the Grand River Dam Authority at its Salina plant. The study addresses problems such as cavitation...

Molluscan Communities of Laguna Madre, Texas: Man's Impact
The purpose of this study is to test the hypothesis that due to human intervention the two parts of the Laguna Madre now differ in molluscan species composition and the most heavily-impacted...

A Prospective Study of the Oyster-Farming in Senegal, West Africa
Various coastal lagoons and estuaries of the region have become oversaline as a consequence of the persistant drought across Sahel. We have monitored the possible consequences of hight...

Salinity Intrusion Predictions by Analytical Expressions
Salinity intrusion in estuaries has traditionally been predicted by use of physical models and more recently by numerical models. Analytic techniques have seen quite limited use because...

Comparing Two Estuarine Mass Transport Models
Two simplified mass transport models for partially mixed estuaries were evaluated using data from the Patuxent and James Estuaries. The first of the models was developed by Pritchard in...

Development of a Self-Heating Thermal Probe for Saline Permafrost
Geothermal modelling and prototype testing are described to support the development of a self-heating thermal probe. This has application for in-situ determination of the amount of unfrozen...

Time Dependent Material Properties Due to Solute Redistribution in Frozen Marine Soils
The design of earth structures and foundations in arctic marine environments requires the assessment of soil properties. A study is presented which investigates the change in mechanical...

Desalination of an Impounded Estuary
The Sungei Seletar, an arm of a saline tidal estuary surrounding the Island Republic of Singapore, has been dammed for conversion to a freshwater reservoir. Calculations for predicting...

The Suwannee River Estuary: Cohesive Sedimentation
Cohesive sediment dynamics as effected by salinity intrusion are described for the Suwannee River Estuary, a large estuary flowing over the very shallow limestone shelf of Florida's...
