Two-Dimensional Finite Element Simulation of the Flooding Characteristics in Kawainui Marsh, Hawaii
This paper summarizes the results from the calibration and application of a two-dimensional finite element model capable of simulating the complex circulation characteristics of Kawainui...

Performance Test of Some Selected Sediment Transport Formulas
Performance of some selected sediment transport formulas was tested using a parameter-sensitivity analysis and a series of numerical experiments with an imaginary channel data. Selection...

River Sediment Discharge Study?San Diego Region
Procedures and general results are presented of a recent study performed to estimate the average annual sediment delivery (sand sizes and larger) from sources discharging to the southern...

Practical Applications of 2-D Hydrodynamic Modeling
Two-dimensional hydrodynamic modeling capability has greatly impacted the hydraulics community and significantly altered the approaches to design and analysis of open channel systems....

Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...

Cumulative Impacts Analysis on a Midwest Fluvial System
The US Army Corps of Engineers recently completed an analysis of the cumulative impacts of erosion control structures on the Platte River in Nebraska. This was done in response to concerns...

Geomorphic and Sedimentologic Evaluation of a Proposed Flood Control Project, Truckee River, Reno, Nevada
Geomorphic observations, sediment data and shear stress analyses were integrated to evaluate the potential responses of the steep, coarse grained Truckee River to a proposed flood control...

The Development of a Plan of Study to Evaluate the Physical and Biological Effects of Increased Navigation Traffic on the Mississippi River
An integrity team prepared a Plan of study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), to identify and quantify impacts associated with commercial...

Experimental Study on the Hydraulic Characteristic and Trapping Efficiency of a Vortex Tube Sediment Trap
In this paper, an expression of water extractor ratio of a vortex tube has been obtained according to the principle of energy conservation and transformation; based on the feature of sediment...

Remotely Sensed Input Data for Real-Time Flood Forecasting
The WATFLOOD flood forecasting system has been developed to use a variety of remotely sensed data, namely weather radar for precipitation, Landsat MSS imagery for land cover classification,...

Discussion of a Three-Dimensional Hydrodynamic Model of the Upper Chesapeake and Delaware Bays
A time-varying three-dimensional (3-D) numerical model of the Upper Chesapeake and Delaware Bays has been developed to address the impact of deepening the Chesapeake and Delaware (C&D)...

Numerical Accuracies in Steady Open Channel Flow
The authors have reviewed the accuracy of the individual terms and formulations of the conservation of energy equation as used within the constraints of steady open channel flow modelling....

Momentum and Kinetic Energy Coefficient Research?Ramp Flumes
In October 1984. Reclamation Hydraulic Branch staff members investigated the operation of the A-Canal ramp at Klamath Falls, Oregon. The ramp flume was completed in 1983 as a water measurement...

Major Sedimentation (Erosion) Issues and Ongoing Research and Developments at the USDA-ARS
The U.S. Department of Agriculture, Agricultural Research Service (ARS) has research programs designed to produce techonology with which to predict, measure, and control erosion and sedimentation...

River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...

Delineation of Ordinary High Water
'Ordinary high water' is used in a court of law to delineate the extent of land ownership of adjacent riparian owners on navigable rivers. The most appropriate...

Modelling of Stages of Nile River as a Tool for a Better Water Resources Management
As far as Egypt is concerned, the Nile is not just a river, it is rather the pulsing nerve of life. Consequently, it was essential to maintain detailed information about its levels and...

Overview of Mathematical Models?River Nile/High Aswan Dam
This paper has been directed towards the presentation of seven reliable planning tools (mathematical models) that can be used for the investigation of the planning options facing policy...

Basin-Wide Stormwater Management in Pennsylvania?A Case Study of Hydrologic Performance Standards
Performance standards in the form of 'release rates' are developed using hydrologic computer models. This basin-wide approach to stormwater management considers...
