DYNLET1: Network Model for Tidal Inlet Dynamics
This paper introduces DYNLET1, an efficient, versatile, and accurate one- dimensional numerical model for computing tidal flow in a system of interconnecting channels and bays. Drawing...

Evaluation of Modelling Parameters for Simulation of Estuarial Systems
Frequently, the purpose of flow simulation in estuaries and complex river systems is to develop circulation patterns for later use. In particular flow and stage time histories are required...

Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...

Innovative Reregulation Weirs
Since their construction, hydropower dams have generated more than just power for the Tennessee Valley Authority, they also generated concerns about their effects on river flow and aquatic...

Climatic Change and Ensuing Risks Facing Water Resources Managers
Global climatic changes will have a significant effect on the utilization of regional water resources and will influence markedly the operation and management of water storage and delivery...

On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....

Sensitivity Evaluation of Simulation Methods for Reliability Assessment
Commonly used reliability assessment methods include the first-order methods, second-order methods, and Monte Carlo simulation methods with or without variance reduction techniques. The...

Stabilizing Drop Structure by Drainage Modifications
East Drain Terminal Drop Structure is located in East Drain, an open toe drain of Palmetto Bend Dam, in the tide water area of south Texas. The drop structure was threatened by piping...

?H and ?4C as Tracers of Ground-Water Recharge
Surface spreading of water from the Santa Clara River is used to recharge aquifers underlying the Oxnard Plain. These aquifers are divided into an upper system about 400 feet thick, and...

Importance of ET on Colorado River Water Quality
Salinity is a major problem in the Colorado River. About 37 percent of the salt loading is contributed by irrigated agriculture activities. Deep percolation and seepage from irrigated...

Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...

Climate Change and Water Management Flexibility
Changes in regional climate expected to occur as a result of the accumulation of greenhouse gases may have significant impacts on water resources. In this paper, I examine the sensitivity...

Water Data of the International Boundary and Water Commission
The International Boundary and Water Commission, United States and Mexico (IBWC) was created by the Treaty of March 1, 1889, between the Governments of the United States and Mexico. Principal...

A Monumental Task
The geotechnical consultants, structural engineer and contractor combined to overcome difficult soils, underground subway structures and buried utilities when building the foundations...

Riprap Design in Marine Terminals
Navigation vessels in otherwise quiescent waterways sometimes generate forces that require stabilization of the bed or banks. Since riprap is an accepted and dependable means to armor...

Water Demand Management in the Las Vegas Valley Region
Water resources in the Las Vegas Valley Region (LVR) are of great concern to the residents and local water purveyors. The chief stimulus for concern is the rapid growth of the region coupled...

Spatial Decision Support System for Toxic Spill Modeling in the Ohio River
Spatial decision support systems (SDSS) are hardware-software systems that incorporate spatial analysis and modeling in a workstation environment. The Ohio River Valley Water Sanitation...

Rock Creek?Cresta Sediment Management Plan
Pacific Gas and Electric Company (PG&E), an investor owned utility serving northern and central California, is working to manage sediments at its Rock Creek - Cresta Hydroelectric...

Computer-Aided Support for Water Quality Modeling of the Russian River
A computer-aided support system for operation of the QUAL2E-UNCAS modeling packaged has been developed for modeling of the Russian River, California. The system has been created under...

Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...
