Modeling Combined Stresses on Aquatic Ecosystems
A mechanistic ecosystem response model is being developed by incorporating exposure/response relationships for selected natural and anthropogenic stresses into an existing hydrodynamic...

Effect of Pump-Ins on California Aqueduct Water Quality
A model has been developed, based on the assumption of constant Aqueduct volume, to predict the effect of ground water pump-ins on Aqueduct water quality. Designated SuperCAMP (California...

Numerical Simulation of Hydraulic Jump
Hydraulic jump is numerically simulated by solving the laterally-averaged governing equations. The governing equations are derived for two-dimensional flow by laterally averaging the time...

Application of a Three-Dimensional Model to Assess Seawater Intrusion in the South San Diego Embayment
The San Diego Formation is a Pliocene through Quaternary age aquifer occupying the southwestern-most part of San Diego County. Though the formation is widespread, thicknesses of up to...

Transport Modeling of the Coastal Waters of Oahu, Hawaii
A hydrodynamic model of the coastal waters around the island of Oahu, Hawaii has been constructed to provide quantitative information on the movements and mixing of water that are to be...

Comprehensive Modelling of Water Distribution Networks
An analyst of a water distribution systems must frequently contend with a host of problems with very different time scales. Traditionally, such concerns have been accommodated by having...

Moving from a Model to a Decision Support System: Salt River Project's Experience with a Reservoir Simulation System
The Salt River Project (SRP) is in the third year of a process to develop a computerized hydra-meteorological decision support system (Hydromet) that will eventually cover all aspects...

Storm Drainage GIS, Modeling, and Master Planning for the City of Berkeley
The City of Berkeley has completed its Storm Sewer Master Plan. The master plan com bined the findings of field inspection worig computer-based mapping, and geographic information system...

Derivation of New Dispersion Coefficient Equation for Natural Streams
A new simple method for predicting dispersion coefficient by using hydraulic and geometric data easily obtained in natural streams has been developed. Dimensional analysis was implemented...

Solving Collection Problems to Increase Revenue: The Houston Experience
By concentrating on improving customer service the City of Houston Utility Customer Service division solved their collection problems and increased their revenues. This article discusses...

Design of a Floodplain Road Crossing Using Two Dimensional Modeling
A two dimensional hydraulic model (FESWMS) is prepared to evaluate flood conditions for the Canal Parkway Project, located in western Maryland. The parkway includes a 32 meter bridge replacement...

Use of ??8O and ?D to Define Seawater Intrusion
On the basis of previous studies, more than 60 km? of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...

Evaluating Strategies to Manage Seawater Intrusion
A simulation-optimization model has been developed to evaluate strategies for managing seawater intrusion in the Oxnard Plain, Ventura County, California; however, this model addresses...

Three Dimensional Particle Tracking Model for the Sacramento-San Joaquin Delta
Flows into and out of the Sacramento-San Joaquin Delta are presently regulated in part by threatened and endangered fish species concerns. To aid in planning future project operations,...

Emulation of DWRDSM using Artificial Neural Networks and Estimation of Sacramento River Flow from Salinity
Artificial Neural Networks (ANNs) are widely used and well-suited for multiple non-linear regression. Department of Water Resources Delta Simulation Model (DWRDSM) is a computer model...

Reducing Model Study Time and Improving Reliability
Historically, the majority of effort expended in computer modeling of physical systems has gone into the numerical algorithms used in the computer programs. Other aspects of modeling have...

Large River Diversion Optimization Considering the Uncertainties Involved
Temporary river diversion during major construction (i.e., large dams) is a challenging job. Selection of diversion system capacity and the dimension of the system components are subject...

Coastal Dynamics '95
Demands to both utilize and preserve the beaches of the world require improved understanding of the underlying dynamics of the coast, as well as better modeling capabilities. To these...
