Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...
Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...
The Tunnel That Transformed Philadelphia
The 1985 Outstanding Civil Engineering Achievement is the Center City Commuter Rail Connection, a 1.7 mile tunnel connecting two former stub-end railroad stations in Philadelphia. The...
Effects of Vehicles on Buried, High-Pressure Pipe
The mechanical effects of selected types of traffic on buried, high-pressure steel pipe are examined. Particularly considered is a section of the Colorado Interstate Gas (CIG) pipeline...
Influence of Depth-of-Cover on Pipe-Soil Interaction
A major research effort was undertaken to study the structural behavior of a natural gas pipeline under several critical service conditions. The program included a field test site near...
An Instrumented Soil-Pipe System: Automated Data Acquisition and Management
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe resulted in a heavily trafficked...
Unique Installation Methods for Large Interceptor in Poor Soil Conditions
The construction of approximately 1. 5 miles of a major sewer interceptor in downtown Boston encountered some unique construction challenges. The entire route required dewatering during...
Longitudinal Prestressed Piping for District Heating
The design of recently installed hot water district heating systems in the United States is based on similar systems developed in Europe. Longitudinal prestressing is used in the design...
Stiffness Requirements for HDPE, Profile Wall Pipe
For the past two years the Gulf Oil Corporation has sponsored a research study on profile wall High Density Polyethylene (HDPE) pipe at Texas A & M University. A pipe design computer...
Buried Fiberglass Pipe Response to Field Installation Methods
In 1970 near Yuma, Arizona, a field test installation of 30 inch diameter fiberglass pipe was constructed. Twelve years later the pipeline was remeasured. Measurements of pipe profile,...
Stress and Strain Responses of a Soil-Pipe System to Vehicular Traffic
A 16-in. natural gas pipeline near Racine, Wisconsin, had been in service for some 30 years. In 1982 road widening operations on a line parallel with the pipe presented the opportunity...
Floodplain Modeling for the Henry Street Basin
A study focusing on the primary conveyance system in the 5. 7 mi**2 Henry Street Drainage Basin in Hillsborough County, Florida was conducted to develop remedial measures for the control...
Comparing Flood Stage-Discharge Data?Be Careful!
A long term stage-discharge record is extremely valuable data. However, simplified applications of long term records to draw sweeping conclusions about man's effects should be avoided,...
Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
Computational Model for Computing Dune Erosion
This paper summarizes the development of a computer model for determining potential beach and dune erosion along the Florida Panhandle. The results have been used as a guide in delineating...
Simulating Flow in the Tidal Potomac River
A one-dimensional unsteady flow model has been applied to the tidal Potomac River, including its major tributaries and marginal embayments, between Washington, D. C. and Indian Head, Md....
Tidal Flooding Study for a Seattle Watershed
The paper reports on a study to develop a correlation between rainfall volumes and tidal storm surges based on recorded rainfall and tide data. This correlation was used to establish tidal...
Real-Time Monitoring for Ohio Basin Water Management
The Ohio River Division (ORD) of the Corps of Engineers operates 77 reservoirs in this basin for the purposes of flood control, conservation, hydropower, low flow augmentation, water supply,...
Real-Time Monitoring and Flood Forecasting in Harris County, Texas
A new automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 90 sensors are automatically...
