Use of a Modified Hybrid Model to Analyze the Effectiveness of Jetties in Reducing Marina Sedimentation
The effectiveness of the construction of jetties near the entrance channel of a coastal marina in reducing marina sedimentation has been analyzed using a modified hybrid model. The modified...
Verification of a Three-Dimensional Model of Delaware Bay
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
A Wind Driven Lake Circulation Finite Element Model for the Upper St. Marys River
The hydrodynamics of the Upper St. Marys River is simulated by a three dimensional steady state finite element model. The rigid lid and hydrostatic pressure assumptions are used in the...
Climatic Perspective on the 1993 Mississippi R. Flood
The 1993 summer flooding in the Upper Mississippi River Basin was the most devastating flood of modern times with damage estimates in the range of 15-20 billion dollars. The paper describes...
The Miller City Levee Break and Incipient Meander Cutoff
On July 15, 1993, the flooding Mississippi River broke through a levee near Miller City, Ill., at the head of the Mississippi Embayment, approximately 55 km upstream from Cairo, Ill. Flow...
Bias in Regression Estimates of Manning's n
Selected equations for estimating roughness for gravel-bed streams were tested using a composite data set containing much of the data used to define the equations. All equations tested...
Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...
San Francisco Bay Test Case for 3-D Model Verification
This paper describes a field test case for 3-D hydrodynamic model verification using data from Carquinez Strait in San Francisco Bay, California. It will be disseminated by the ASCE Computational...
Ambrose, R. B.
Numerous three-dimensional hydrodynamic models have been developed in the last two decades. The developers of each model have used their own methods to verify the codes before applying...
Identification of A Field Data Collection Program in Delaware Bay
Verification and the subsequent application of a numerical model requires sufficient field data to demonstrate that the model is reproducing the existing hydrodynamics of the modeled system....
Numerical Modeling for Sediment-Pass-Through Operations of Reservoirs
Numerical modeling using the FLUVIAL-12 model was made to determine the feasibility and effectiveness for Sediment-Pass-Through (SPT) operation for Cresta and Rock Creek Reservoirs in...
Scour Hole Depth Downstream of the SAF stilling Basin
A Model to predict the maximum local scour depth downstream of the SAF stilling basin is presented. The model is based on stability analysis of a particle attacked by the hydrodynamic...
Evaluation of Six Methods for the LP3 Distribution
Six frequently used estimation methods for the Log-Pearson type 3 distribution were evaluated using both the predictive and the descriptive performance indices. Ten LP3 populations and...
Sediment Transport Analysis Rio Grande Floodway at San Marcial Gauge
A detailed analysis of sediment transport data collected on Rio Grande Floodway at San Marcial gauge shows that the all-year total load rating curve and the seasonal rating curves yield...
An Interagency Overview of Selected Stream Sedimentation Models
The author's experience in developing stream sedimentation models is presented. The interagency study consisted of three phases. Phase one involved making an inventory of the computer...
A Watershed Model for Estimating Suspended Sediment Hydrographs
A mathematical model was developed to estimate soil detachment and transport and, consequently, suspended sediment hydrograph for single storms on a watershed basis. In this linear cascade...
A Better Description of Trap Efficiency for Fine Sediment in Horizontal Settling Basins
Settling basin removes sediment from intake water and enhance the benefit of diversion works. In order to economize construction land and cost as well as for agriculture fertilization...
Modeling Hydrologic and Pollutant Transport Processes for Stromwater Runoff to Surface Waters
Combined sewer overflows and stormwater discharges, which are considered point sources, and certain nonpoint sources (NPSs) display the characteristics of precipitation-driven events....
Thermo-Hydrodynamic Modelling of the Chicago Sanitary and Ship Canal
A one-dimensional numerical model of the Chicago Sanitary and Ship Canal and Lower Des Plaines River has been developed as a tool for assessment of the waterway's thermal response to actual...
Development of Long-Term Three-Dimensional Hydrodynamics in Long Island Sound for Use in Water Quality Modeling
The Blumberg-Mellor (1987) three-dimensional hydrodynamic model has been adapted by the National Oceanic and Atmospheric Administration's National Ocean Service (NOS) to provide hydrodynamic...
