Reliability Analysis of Pumping Stations and Storage Facilities
The methodology presented for pumping stations is based upon three models: a supply model, a demand model, and a margin model. The supply model considers so-called states of a system which...
Model for the Optimal Rehabilitation and Replacement of Water Distribution System Components
The objective of the model presented is to determine the minimum cost solution, given the nonlinear nature of the equations required to describe the cost and the hydraulics of a water...
Comparing Two Estuarine Mass Transport Models
Two simplified mass transport models for partially mixed estuaries were evaluated using data from the Patuxent and James Estuaries. The first of the models was developed by Pritchard in...
Basin: A Simple Yet Many Faceted Model for Estuarial Impoundments
BASIN is a hydrodynamic and water quality model designed to provide a simplified analysis of flows and constituent concentrations in both tidal and non-tidal water bodies. BASIN is excellent...
Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...
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...
Physical Modeling to Study the Extent of Removal of an Existing Lock and Dam on the Mississippi River
Locks and Dam No. 26 is located on the Mississippi River approximately 202. 9 river miles above the mouth of the Ohio River. This paper will discuss the utilization of a physical model...
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...
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....
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...
Input Programs for Engineering Applications
This paper discusses several input program types and the data structures associated with them. Two input programs were designed for KYPIPEF to demonstrate the use of files of records and...
Composite Resistance to Flow With an Ice Cover
Recent data collected on several rivers in Michigan suggest, with only an ice cover present, that Manning's roughness ratio is constant at n//R equals 0. 65. If other ice...
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...
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,...
Mississippi River Sediment Load and Regime Equations
Data collected by the Corps of Engineers were used to evaluate the interaction of such parameters as river slope, suspended sediment load, channel geometry, and river discharge. Calculations...
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...
