Air Power Boosts Utility Energy Supplies
Based in part on successful findings of tests, in which compressed air was stored in underground aquifers, Central Illinois Public Service engineers are investigating a type of pumped...

Model-Prototype Correlation of Hydraulic Structures
Forty-three papers are contained in these proceedings, from the International Symposium on Model-Prototype Correlation of Hydraulic Structures. The papers cover a broad range of subjects...

New Found Youth for an Old Foundry
The Grey Iron plant, central foundry division of General Motors Corp., in Saginaw, Mich. conducted a study to evaluate the capacity and tooling of future casting operations of the more...

Renewing San Diego Pumping Station No. 64
Pump Station 64 has experienced a number of sewage overflows into Penasquitos Lagoon since 1979 (57 in total). The California Regional Water Quality Control Board (CRWQCB) issued a Cease...

Settlement of Residual Soils
The method previously suggested by the author in 1977 for calculating settlement of non-plastic to slightly plastic Piedmont Physiographic Region residual soils is reviewed. Additional...

Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...

Forecasting Currents in Coastal Waters
A service for current and temperature forecasts has been developed for the coastal waters along the west coast casts has led to several improvements. Future modeling efforts are expected...

Effect of Permeameter and Leachate on a Clay Liner
Hydraulic conductivity tests were performed on a natural clay liner material using leachate from an active Type II landfill. Comparative tests were conducted using flexible wall permeameters,...

Water Jets: Concrete Yes, Tunneling Maybe
High pressure water jets are demolishing concrete from bridge and parking decks, faster and at lower cost than by traditional means. The technique is fast becoming an acceptable option....

Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...

Design of Semi-Closed Pipeline Systems
Semi-closed pipeline systems controlled by downstream activated float valves permit low pressure pipeline systems to communicate information from the outflow location back to the source...

Case Study?Closed Pipeline Systems
The paper discusses closed pipeline system and its automation, including variable pumping rates, sensing devices, automatic controls, pressure regulators, flow measuring devices, surge...

Yakima-Tieton Irrigation District Rehabilitation Program
The Yakima-Tieton Irrigation District obtained funding from the U. S. Bureau of Reclamation and the State of Washington to replace an open canal and lateral irrigation delivery system...

Simultaneous Releases from a Stratified Reservoir
The concept of simultaneously, selectively withdrawing water from multiple levels in a thermally, and therefore density, stratified reservoir is presented and its usefulness discussed....

Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...

Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...

Pressure Fluctuations on the Floow of Hydraulic Jumps
This paper presents the results of an experimental investigation regarding the variation of r. m. s. value of pressure fluctuations on the floor of free and forced hydraulic jumps formed...

Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...

Minimum Energy Loss and Velocity Profiles in Pipes
Minimum energy loss in a flow is discussed. The concept is applied to derive velocity distributions for laminar flow through a circular pipe and steady uniform turbulent flow through a...

Numerical Modeling of Column Separation with Large Pressure Pulses
Liquid transients involving column separation occur in pipelines when the pressure drops to the vapor pressure of the liquid. The collapse of vapor cavities may result in short duration...
