Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....

Monitoring Water Quality: Neches Estuary, Texas
A continuous monitoring project has been established in the Neches Estuary of Southeast Texas, for the purpose of investigating the influence of tidal hydraulic on sedimentation in a floating...

A Simulation Technique for Modeling Flow on Floodplains and in Coastal Wetlands
The system design is premised on a proven, areal two-dimensional, finite-difference flow/transport model which is supported by an operational set of computer programs for input data management...

Two-Dimensional Numerical Flow Models, Built and Used by Civil Engineers
The paper describes the WAQUA system, a series of programs to perform two-dimensional hydrodynamic and water quality simulations. Long term developments resulted in a successful system...

Twenty Years of Experience in Unsteady Flow Modeling of Open Channels at TVA
Two concerns prompted the development of dynamic methods for flow routings: (a) the safety of the nuclear plants being planned along the Tennessee River in the 1960's and...

A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...

Physical River Model Results and Prototype Response
The Hydraulics Laboratory of the US Army Engineer Waterways Experiment Station (WES) has performed physical hydraulic model studies on various rivers for nearly 60 years. These studies...

Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...

Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...

Channel Response to SCS Type-C Grade-Control Structures on Burney Branch, Mississippi
Five SCS Type-C grade-control structures were installed in Burney Branch in 1980 to remove 59.4 feet (18.1 m) of grade. The performance of the structures was evaluated in 1984 after they...

One-Dimensional Tidal Circulation Model
A finite-element, one-dimensional numerical model of tidal circulation was developed for estuarine and channel flow applications. The model was designed for the prediction of tide heights...

Simulation and Video Animation of Canal Flushing Created by a Tide Gate
A tide-gate algorithm was added to a one-dimensional unsteady flow model that was calibrated, verified, and used to determine the locations of as many as five tide gates that would maximize...

The BRANCH Model and the Segara Anakan Study
The Lower Citanduy Irrigation Project in Central Java, Indonesia drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems,...

Analysis of Spillway Failures by Uplift Pressure
Results of a model study to evaluate the development of uplift pressures beneath concrete chutes are presented. Two spillway failures are described to support the study results. Common...

Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...

Mathematical Model of Wave Induced Pressures
A two-dimensional, implicit finite difference model was built to compute surface wave induced pressures under a gravity base foundation. The results showed considerable wave attenuation...

Bay/Delta Hydraulic Model?Thirty Years of Service
The San Francisco Bay and Delta is an extremely complex estuarine system. During the past thirty years, the San Francisco Bay/Delta Hydraulic Model has proven to be a valuable scientific...

Three-Dimensional Modeling of a Stratified Estuary
Development around Choctawhatchee Bay, and reduced productivity, loss of seagrass beds, and higher salinities, prompted the Northwest Florida Water Management District to conduct an investigation...

A Marina Model of Continuous Loads and Equilibrium
For projects requiring dredge and fill permits from the Florida Department of Environmental Regulation (FDER) the impact on water quality is one of the primary areas of concern which must...

Harbor Restoration Through Improved Circulation
After several episodes of massive fish kills in Old Pass Lagoon on the Florida Gulf Coast, an investigation was undertaken to identify the problems and propose cost-effective solutions....
