Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...
Reinforcement of Steep Grassed Waterways
A collaborative research program has been undertaken in the UK to develop guidelines for the use of various proprietary reinforcement systems to enhance the erosion resistance of grass...
Modelmania
The idea that model testing could be useful in planning for the control of water in rivers and other waterways received little support in this country until John R. Freeman's...
Advanced Concept for Generation of Waves in Hydraulic Models
This paper describes a new wavemaker for the generation of naturally occurring waves in physical models of coastal areas. Recent research incorporating directional aspects of monochromatic,...
Uncertainty in Models for Environmental Management
In recent years, computer models have become increasingly popular as tools to aid the decision-maker in balancing complex, interacting factors in environmental management and pollution...
Network Analysis for Water Supply Reliability Determination
The availability of water at a point in a distribution network is expressed in terms of the reliabilities of the components which comprise the different paths to the point from the source....
Capacity Expansion of Water Distribution Systems?A Case Study
Capacity expansion and necessary capital improvements to meet the water supply demand for years 1990-2020 for the U. S. Route 1 corridor development from South Brunswick to Princeton,...
Developing a User Friendly System for Water Distribution Management Applications
A hydraulic computer model of a water distribution system that can be updated with current billing (customer meter readings) information automatically. The model was calibrated with field...
Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...
River Wave Response to the Friction-Inertia Balance
The changing character of the solution of the Saint-Venant equations for river flow problems with the dimensionless parameter F//I reflects a changing balance between friction and inertia....
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...
