Physical Modeling to Determine Head Loss at Selected Surcharged Sewer Manholes
The head losses at sewer pipe junctions (manholes) under surcharged conditions were measured in a 1:6 scale model of a typical manhole with one main line passing through it and two perpendicular...
Analyzing Water Balances and Ranking Maryland's Watersheds Related to Growth, Development and Loss of Habitat
One hundred thirty three watersheds comprising the entire state were analyzed for surface and ground water balance. Census population figures (1990) were allocated to the watersheds. Population...

The Cold Regions Infrastructure?An International Imperative for the 21st Century
This volume includes papers presented at the Eighth International Conference on Cold Regions Engineering?The Cold Regions Infrastructure: An International Imperative for the 21st Century....
Honolulu's Street Relief
Engineers faced the daunting prospect of burying a new relief sewer under a busy Honolulu highway with trench-cut methods. The contractor suggested microtunneling, but the coral reef formations...
Detecting Leaks Electronically (Available only in Geo/Environmental Engineering Special Issue)
An innovative monitoring system originally developed to detect cyanide leaks at gold mines can now monitor the integrity of geosynthetic liners at municipal- and hazardous-waste landfills...
Lessons From Kobe
On Jan. 17, Kobe, Japan became the first post-World War II, heavily populated, industrialized area to bear the full brunt of a high-magnitude earthquake. Engineers hope the resulting destruction...
Impact-Echo Strikes Home
Diagnosing flaws without destroying the structure is the first step to cost-effective repairs. Impact-echo is one of the more successful nondestructive evaluation (NDE) methods that have...
Engineering a Landslide
A slope failure in northwest Alabama has been stabilized using a system of grouted INSERT piles to provide load transfer across the failure surface of the slide. This system, referred...
Advances in Underground Pipeline Engineering II
The first international conference on Advances in Underground Pipeline Engineering was held in 1985. Some 50 authors and over 300 delegates from 20 countries took part in the presentations...
Waste Containment Facilities
This book presents a comprehensive description of recommended procedures for construction quality assurance (CQA) and control (CQC) for waste containment facilities. Chapter 1 describes...
Trenchless Relief
During wet weather, stormwater infiltration/inflow into the sewer system increases wastewater flows by 8-12 times the average dry weather flow in several interceptors operated by the Central...
Enabler Chassis Features and Mobiltiy Analysis
The Enabler is a proposed Lunar Base work vehicle. The unique construction of the Enabler's six-wheeled chassis provides unusual articulation for steering, balancing, and overcoming obstacles....
A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...
Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...
Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...
Water Conservation and Delivery Flexibility in the Imperial Irrigation District Through Lateral Interceptor Systems
The lateral interceptor concept was conceived in the wake of a water conservation effort to reduce several sources of water loss typical of irrigation districts. These sources include...
Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...
