Hydraulic Design of Flood Control Channels
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 10. This guide presents procedures for the design analysis...
Wider Ride to the Rainbow
Engineers on the project to widen the entrance to the Rainbow Bridge between New York and Ontario let the aesthetics of the Niagara Falls setting dictate their design decisions. The challenge...
Failures in Civil Engineering
Structural, Foundation and Geoenvironmental Case Studies
This special publication consists of a collection of short descriptions of failures case studies in Civil Engineering. The descriptions cover cases in structural, foundation and geoenvironmental...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...
SQP Methods for Inverse Airfoil Design
We consider inverse design problems of systems governed by suitable discretizations of a boundary value problem (BVP). We present and examine a Sequential Quadratic Programming (SQP) method...
Simulated Circulation and Transport in Adjacent Wind-Driven Estuaries in North Carolina
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
The Formation of a Turbidity Maximum in an Estuary
In the present study, a numerical model is used to investigate the transport of sediments in a stratified estuary. The model includes sediment resuspension and deposition as well as three-dimensional,...
Demonstration of the Wes New York Bight Hydrodynamic Model in Long Island Sound
Recently, a three-dimensional numerical hydrodynamic model of the New York Bight developed by the Waterways Experiment Station was applied to the Long Island Sound subregion, using NOAA's...
Solutions of Primitive Equations for Three-dimensional Tidal Circulation
Readily available computing resources and new numerical methods have made it possible to reproduce detailed three-dimensional tidal circulation with very fine spatial resolution, and covering...
Comparison of Eulerian-Lagrangian, Random Walk and Hybrid Methods of Modeling Pollutant Transport
An Eulerian-Lagrangian, a random walk, and a hybrid model were compared in terms of their accuracy and efficiency in simulating two-dimensional pollutant transport. Computer experiments...
Experimental Study of Undertow and Turbulence Intensity Under Irregular Waves in the Surf Zone
Experiments are performed in a two-dimensional wave tank with a sloping beach. Irregular waves are generated and the water particle velocity is measured in the surf zone with a laser Doppler...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
A Satellite Based River Forecast System for the Nile River
The initial version of the Nile Forecasting System developed by NOAA was used operational in July, 1993. Forecast System accuracy exceeded expectations. The Nile Forecast Center is now...
Tailwater Fishery Management Using a Fish Bioenergetics Model
Water releases from TVA reservoirs exert great influence on downstream water quality. Analytical tools to quantify biological response to altered environmental conditions, such as dissolved...
Modeling Municipal Water Demands for a Pump Station Area
The Chasewood Pump Station/Residential Area in southwest Houston was selected for a detailed analysis of ground and surface storage water pumping by a University of Houston and City of...
Parameter Regionalization of a Daily Baseflow Runoff Model
Daily baseflow values are required to characterize the environmental measurements being carried out in several basins in the Province of Genova, northern Italy. The main purpose of these...
Effects of Lateral Heading Flow Steadiness on Lateral Spillage
Hourly inflow and spillage rates from three lateral canals in the Imperial Irrigation District in Southern California were measured for seven months and subsequently analyzed to identify...
Using GIS to Develop 2-D Hydraulic Models
As communities along rivers and streams continue to develop, the demand for more accurate floodplain analysis and flood warning will also increase. Computer systems continue to develop...
