Modeling Unsteady One Dimensional Open Channel Flow Using the Slope Friction Form of the Saint-Venant Equations
The flow of water in open channels has been an important research topic for many years. In 1871, B. De. Saint-Venant published a set of equations that attempted to quantify the physical...
Magnitude and Frequency Analysis in Large Rivers
A study of the magnitude and frequency of sediment transport was conducted on the Mississippi River at Natchez, MS, Red River at Alexandria, LA, and Pearl River at Bogalusa, LA. The individual...
Segregation of Sediment During Deposition
A laboratory experiment was conducted to investigate the segregation of sediment during deposition. Sediment eroded from an upslope source area of Blount silt loam was introduced to a...
Pipe Network Analysis on a Microcomputer
This paper reports on experience gained with the use of commercially available software for pipe network analysis. This information may be helpful to water system managers and consulting...
Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....
Effects of Land Subsidence on Flood Profiles
In this study, the effects of land subsidence on water-surface elevation and depth profiles during flood conditions were investigated for a large, hypothetical, slope-controlled stream....
Comparison of Some River Discharge Calculation Methods
To measure the discharge of a river, it is necessary to develop a stage-discharge curve based on water velocity at various cross sections of the river. This is the method which is used...
Evaluting the General Well Function
The closest thing to a mathematical function that maps well discharge to drawdown has been Jacob's equation, caled the step-drawdown equation. However, this equation assumes the drawdown...
Alternative Methods for Representing Sinkholes in Three-Dimensional Ground Water Flow Models
Two methods of representing the sinkholes in central Florida were investigated with a three-dimensional finite element model recently developed by Camp Dresser & McKee Inc. Both...
Ground Water Flow Simulation in a Small Drainage Basin
This paper describes the development and use of a numerical simulation approach for predicting ground water flow in a small drainage basin in southern California. The purpose of the modeling...
Dimensional Analyses of Yellow River Sediment Data
A contemporaneous set of bed load and suspended load sediment transport data were analysed for three hydrologic stations on the Yellow River. There were a total of 82 bed load events,...
Sedimentation of Lakes and Reservoirs in Illinois
A generalized analysis of lake sedimentation rates in Illinois provides a representative 'window' on sedimentation rates of midwestern lakes located in humid...
An Analysis of Channel Stability of the Red River from Shreveport, Louisiana to Index, Arkansas
To analyze the stability of the Red River in the study reach (Shreveport, LA to Index, AR) two comprehensive hydrographic surveys were studied. The hydrographic surveys were compared to...
Effects of Reservoir Regulation on Channel Morphology
A case study is presented in which such a multidisciplinary approach was used to evaluate the impacts of regulated outflows from the recently completed Warm Springs Dam Project (Sonoma...
Flood-Control Channel Stability Assessment
Guidelines for conducting a stability assessment of a channel proposed to be modified for flood control are presented in this paper. The basis behind this assessment is that a channel...
Mathematical and Laboratory Modeling of Transport in Partially Saturated Soils
The salient features of a two dimensional flow and solute transport model in partially saturated soils are presented. A Galerkin finite element approach for the numerical solution of the...
Computational Modeling of Sediment Transport in Kachemak Bay
The tide-generated flow circulation in the Kachemak Bay of Alaska was simulated numerically using the Multi-Leveled Finite Element Model originally developed by Kawahara of Japan and recently...
Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
Calculating Runaway Pressure Surges in Small Hydro Units
Determination of the runaway speed and concomitant pressure surges requires consideration of both the turbine rotodynamics and the waterhammer equations. In this paper a simplified method...
Depleted Uranium Migration in Stream Bedload Environment
