Probability and Impact of an Observed Rare Sequence of Floods
Accordingly, it may be concluded that the severity of the recorded sequence would be exceeded in about 2.1 percent of future sequences, or have about one chance in 45 or 50 of being exceeded...

Engineering Hydrology
This proceedings, Engineering Hydrology, contains papers that were presented at the Symposium held in San Francisco, California, July 25-30,...

Guidelines for PC-Based Data Acquisition Systems for Hydraulic Engineering
Guidelines for PC-Based Data Acquisition Systems for Hydraulic Engineering reviews the state-of-the-art in personal computer-based data acquisition...

Development of Detached Breakwater Design Criteria Using a Shoreline Response Model
An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance,...

The Transverse Vortex in the Wall Regions of the Turbulent Boundary Layers in the Flows with Adverse Pressure Gradient
The vortical structures in the turbulent boundary layers in the flow with adverse pressure gradient were investigated by the hydrogen bubble technique. The vortices were visualized in...

Vacuum Melting and Mechanical Testing of Simulated Lunar Glasses
Lunar silicate glasses may possess superior mechanical properties compared to terrestrial glasses because the anhydrous lunar environment should prevent hydrolytic weakening of the strong...

Plot-scale Field Experiment of Surface Hydrologic Processes with EOS Implications
Plot-scale hydrologic field studies were initiated at NASA Marshall Space Flight Center to a) investigate the spatial and temporal variability of surface and subsurface hydrologic processes,...

NetCDF: A Public-Domain-Software Solution to Data-Access Problems for Numerical Modelers
Unidata's network Common Data Form, netCDF, provides users with an efficient set of software for scientific-data-storage, retrieval, and manipulation. The netCDF file format is machine-independent,...

Methodology for Validation of a Tampa Bay Circulation Model
The National Ocean Service is presently conducting the Tampa Bay Oceanography Project, including development and application of a three-dimensional circulation model to the Bay, and collection...

Modeling Three-Dimensional Circulation and Sediment Transport in Lakes and Estuaries
The transport of fine sediments due to currents and wind waves in estuaries and lakes have been studied by means of field experiments, laboratory experiments, and a comprehensive three-dimensional...

Thirty Year Simulation of Chesapeake Bay Eutrophication
Eutrophication processes in Chesapeake Bay, 1959-1988, are simulated using a three-dimensional model package. Results link the volume of anoxic water to degree of stratification and to...

Experiments with a Terrain-Following Hydrodynamic Model for Cobscook Bay in the Gulf of Maine
A terrain-following (sigma-coordinate) hydrodynamic model with 10 vertical levels and horizontal resolution of 225 m on a 70?60 grid has been applied to Cobscook Bay, located in the eastern...

A PC-Based Integrated Water Quality Impact and Analysis System
An integrated water quality model system (WQ Shell) has been developed for the PC. The system is designed to provide an easy-to-use graphical interface which integrates geographical and...

A Numerical Model Simulation of Tidal Currents in Long Island and Block Island Sounds
A case study evaluating the predictive capability of a hydrodynamic model of Long Island Sound is presented. The model is a time dependent, three-dimensional, primitive equation, estuarine...

3D Hydrodynamic Model Validation Through Simulations of Dynamic Processes
Two test cases with idealized geometry and forcing functions were performed to validate a three dimensional hydrodynamic model for use in coastal waters. The tests involve the barotropic...

Effects of Wind on Circulation in Los Angeles-Long Beach Harbors
A three-dimensional hydrodynamic model was applied previously (Vemulakonda and Butler 1989) to Los Angeles-Long Beach Harbors to determine tide and wind-induced circulation. The model...

Hydrodynamic and Water Quality Modeling of Lower Green Bay
A confined disposal facility (CDF) for dredged material presently exists in lower Green Bay, Wisconsin. A planned expansion of the CDF is being studied to assess its impact on current...

Modelling of Coastal Circulation in Singapore Waters?A Hybrid Approach
A hybrid modelling technique which involves the integration of numerical and physical models has been used to study tide induced circulation in Singapore coastal waters. The modelling...

A Predictive Model of the Currents in Cleveland Bay
A two-dimensional (depth-averaged) numerical model is proposed to describe the hydrodynamics of Cleveland Bay and is used to investigate the water circulation within the Bay. By utilizing...

Environmental Impacts of Agricultural Drainage
Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow...
