Hydrodiplomacy on Forester Creek
The goal of this paper is to share information regarding political battles confronting the engineer with regards to drainage issues and concerns. Very often drainage boundaries do not...
A Survey of Stormwater Infiltration Basins in the Puget Sound Region
A survey of 23 infiltration basins in the Puget Sound area was conducted to gain information on the performance of these systems and the degree of compliance with state agency guidelines....
Survey of Stormwater Detention State of Practice
A survey of stormwater professionals in the United States and Canada was conducted by the Urban Drainage and Flood Control District in 1991 regarding the current state of practice in the...
Use and Abuse of Settlement Analysis
Terzaghi's concept of settlement analysis included comparison of prediction with reality and investigation of the causes of the differences. Present usage is often limited to prediction....
Settlement of a 15-Meter Deep Fill Below a Building
The site for a building in western Pennsylvania was undermined, with the mine base about 15 m below planned final grade. Rock above the mine was highly fractured and of poor quality, indicating...
Finite Strain Consolidation for Vertical Drains
Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain...
Compaction Grouting Stops Settlement of an Operating Water Treatment Plant
In early 1978, about a month into full-time operation, the new filter plant building for the water treatment plant for the City of Glenwood Springs, Colorado, experienced distress due...
Performance of Wick Drains Installed by Vibration
Settlement and piezometer data from construction of fills on Route I-291 in South Windsor, CT is analyzed for total settlement and coefficient of consolidation. The results are compared...
Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...
Consolidation of Ground Reclaimed by Inhomogeneous Clay
A large amount of prefabricated band drain was installed to improve the ground reclaimed by soft soils at the enlargement project of the Tokyo International Airport. By analyzing data...
Heavy Metal Removal Using Peat/Wetland Treatment
The purpose of this paper is to present an overview of the mechanisms and application of a peat/wetland treatment system for heavy metal removal from wastewater. The mechanisms involved...
Pipe Utility Evaluations With the Aid of GIS
Geographical Information Systems (GIS) are starting to be used on a day to day basis to solve community problems and optimize the use of their valuable resources. One engineering application...
Hydraulic Model Studies of Recessed Curb Inlets and Bridge Drains
A large hydraulic model (64 ft long by 10.5 ft wide) was used to test several geometries of recessed curb inlets and three types of bridge drains. Testing was at 3/4 scale for the recessed...
Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...
Discharge-Frequency Relationships in Distributary Flow Systems
The paper describes discharge-frequency relationships in distributary flow systems. The stream network that makes up the flow system is described in terms of how the various stream segments...
America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...

Geotechnical Baseline Reports
The greatest percentage of disputes in underground construction results from subsurface conditions that are different than from what is indicated in the contract. Adding geotechnical baseline...
Protecting a Pipeline
A 30-inch oil pipeline, presently under construction through mountainous terrain in central Colombia, transports petroleum from the Cusiana oil field to the coast. The discovery of the...
Taming the Urban Underground
When designing and installing excavation support systems at a city construction site, be prepared to deal with the urban jungle. Tunnels and utility cables and pipes clog the underground,...
