Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...
The Effects of the 1985 Mexico City Earthquake on Underground Water & Sewer Pipelines
The 1985 Mexico City Earthquake left thousands dead and many thousands more without shelter. The visible damage was immense and terrible, and familiar to people around the world through...
Seismic Restraint of Hazardous Process Piping
The lack of appropriate guidelines for the design and installation of hazardous process piping in industrial facilities has created a potentially dangerous situation. Process piping carrying...
Response of Underground Pipelines to Dynamic Loads
The results of an investigation of the forced response of an underground pipeline due to dynamic loads are presented. The pipe is modelled as a linearly elastic shell element and the surrounding...
Port Expansion of Eastport, Maine
A recent pier expansion now allows Eastport to provide 40 feet of water at low tide. The pier expansion consists of a concrete-decked steel pipe pile-supported extension to an existing...
Rehabilitation of Wharf No. 8?Port of Houston
A routine inspection of wharves at the Turning Basin Terminal, uncovered evidence of extensive damage, including evidence that the 30-inch diameter steel pipe piles supporting Wharf No....
Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
Computer Modeling of Collection Systems for Sulfide Evaluation (
An overview of two computer models and a nomograph model for sulfide prediction is presented. The first program, 'SULF. BAS', is a Basic Language computer model...
Controlling Sulfide Corrosion in Large Diameter Gravity Sewers (
The County Sanitation Districts of Los Angeles County undertook a major evaluation of sewer system ranging in size from 1. 22 to 3. 65 meters in diameter that transports peak wastewater...
Sulfide Corrosion and Control in the City of Modesto Primary Effluent Outfall (
The City of Modesto has a 60 inch diameter, 6- one-half mile long reinforced concrete pipeline conveying primary effluent from the primary treatment plant to the remote oxidation pond...
Hydrodynamics of Earth Fill Dam Breach Erosion
An analytical model is suggested in this paper. The model is based on the continuity equation of water mass within the reservoir, a broad-crested weir discharge formula and a velocity...
Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
Performance of a Deterministic Storm Runoff Model
The paper discusses model comparisons based on a Tulsa, Oklahoma, case study. Modeling strategies were explored, four of which were modeled in detail because of the extremes in range of...
Stormwater Management in Kansas
This paper evaluates the current stormwater management practices of Kansas cities. This evaluation is based on a survey of all Kansas cities with populations over 10,000. Issues examined...
Design Storms for Urban Drainage
The characteristics of design storms for urban drainage are reviewed. There are indications that, under certain conditions, design storms produce runoff simulation results which are equivalent...
On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
The United Kingdom Approach to Rehabilitation
Following concern over the condition and performance of its underground assets, the UK Water Industry has developed strategies for cost effective sewer and water main rehabilitation. These...
Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
