Agricultural Water Conservation Programs in the Lower Colorado River Authority
Rice irrigation is the largest application of water within the area served by the Lower Colorado River Authority, accounting for approximately 75 percent of total annual surface and ground...
Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...
Storm Water Utility Experience in Bellevue, Washington
Surface water management is seen as a flood protector by most, a savior of the environment by some and a subversion of property rights by others. As recently as 20 years ago, there were...
New Wells Safeguard Scenic Tahoe
Surface water for drinking and for snow-making is becoming scarce in the Lake Tahoe region, along the California and Nevada border. New Environmental Protection regulations regarding surface...
Estuary Management: The British Experience
This paper describes two estuary management studies undertaken in south-west England during 1991-92. Despite there being many differences between the studies in terms of why they were...
The Sea Sentinels Project: Watching Waves in Brazil
This paper presents the first results of the Sea Sentinels-a project for monitoring nearshore wave conditions in Brazil by means of visual observations. The observation techniques used...
Effects of Surface Brine Disposal on the Marshes in Coastal Louisiana
In 1986, more than 1 billion barrels of brine were disposed of in Coastal Louisiana. Disposal of brine into surface water body is economically practical but environmentally detrimental....
Evaluation of Plants for Coastal Dune Stabilization
The dune stabilization system used in the Phoenix Condominiums project can be used to enhance dunes all along the Atlantic and Gulf Coast. The plants and technology are available, which...
Coastal Non-Point Source Pollution Abatement: The Shipbuilding and Repair Industry
In cooperation with several shipbuilding and repair businesses and several state environmental regulatory agencies, site visits, waste-minimization assessments, and storm water sampling...
Evaluation and Management of Irrigation Systems in Southwest Florida
The United States Department of Agriculture Soil Conservation Service (SCS) provides assistance to growers in the Southwest Florida area for the evaluation, improvement and management...
Vertical Distribution of Sediment Under Waves
This paper is based on the research foundation of vertical relative distribution of sediment concentration and alluvial bed stability under waves. Amended theories of E. W. Lane and A.A....
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...
The Specific Peculiarities of Relief Transformation and Shelly Sediment Differentiation in Coastal Zone
The settling velocities values of shelly sediment considerably differ from ones of the same particles of terrigeneous material and for this reason character and intensity of hydrodynamic...
A Mathematical Model for Predicting the Motion of Polluting Surface Plumes Due to Drift Currents
The paper analyzes the problem of displacement from the offshore to the nearshore of a polluting surface plume, subject to advection generated by wind-waves and wind-currents. After a...
Flood Damage Mitigation Efforts in a Small Mountainous Community in Jamaica
About 60 percent of the mountainous Caribbean island of Jamaica is underlain by karstic limestone. 'Sinkholes' in this limestone form the natural outlets to many surface waters. During...
Uptake of Contaminants by Overland Flow
A mathematical model is developed for the uptake of contaminants by overland flow. The model is based on the numerical solution of the Navier-Stokes equations coupled with a two-equation...
Lake-Level Declines in Karst Lake During Droughts
Lake-level declines in Brooklyn Lake, a karst lake in north-central Florida, have been investigated. Below average rainfall, vertical leakage to the underlying aquifer system, declining...
Survey of GIS Applications in Surface Water Hydrology
Geographic information systems (GIS), computerized tools for management and manipulation of spatially referenced data, are increasingly being used for engineering analysis and design of...
Design and Analysis of an Irrigation Pond Using Urban Stormwater Runoff
Stormwater held in detention ponds can be reused for irrigation. A simulation of a mass balance on pond storage volume using rainfall and evaporation data for selected areas is presented...
Anisotropic Effects on Flow from a Recirculation Well
We examined flow in an unconfined aquifer near a recirculation well, which consists of a source and a sink of equal strength, with emphasis on understanding the effects of anisotropy....
