Evaluation of TR-55 on Coastal Watersheds
Results of a study of the applicability of TR-55 to coastal watersheds are presented. Historical data were used to evaluate curve number, time of concentration and unit hydrograph peak...

International Research on Mechanics of River Bank Erosion?A Summary Overview
A brief overview is presented of research regarding mechanisms of river bank erosion and treatments. In the research river planforms, water stages, currents, waves, ice sediments, bed...

Clay Joints in the Foundation of Dkhila Dam

Predicted and Observed Axial Behavior of Piles
Results of a Pile Prediction Symposium
This publication presents the results of a pile capacity event that was held at the Lakefill site on the Evanston Campus of Northwestern University in conjunction with the 1989 Foundation...

Bioremediation: Testing the Waters
Piotrowski describes the pilot study that led to the first EPA-mandated use of bioremediation to clean up a Superfund aquifer. (Bioremediation seeks to stimulate microbial activity to...

Storing Sediment and Freeing Fish
When Mount St. Helens erupted in May 1980, it sent a river of pyroclastic ash and other debris into Washington's North Fork Toutle River Valley. The resulting debris pile...

SPIDA Method for Reinforced Concrete Pipe Design
The required supporting strength of buried pipe is affected by the total load that is imposed upon the pipe and the manner in which the pipe is supported by the surrounding soil. The installation...

Segmental Tunnel Lining Meets `Buy American'
Segmental concrete tunnel lining is the other innovation proven during construction of the Washington Metropolitan Area Transit Authority (`wmata'). Although `wmata's'...

Resilient Moduli of Soils
Laboratory Conditions
Historically, structural pavement design has been based on static testing techniques, such as the CBR. More recently, the profession has placed increased emphasis on repeated load testing...

Transferring Construction Innovation into Practice: Lessons Learned
The paper presents several cases that illustrate the value of a systems approach in the need for aggressive and persistent exploitation despite early set-backs, and the unsatisfactory...

Stabilizing a `Mann'-Sized Sinkhole
On Sept. 21, 1988, a sinkhole suddenly developed beneath a transmission/distribution effluent pipeline on Mann Road in Orange County, FL. Initially it measured 30 ft in diameter and 8...

Augering Answers
Leaking storage tanks, a long time environmental problem, are now being addressed nationally with cleanup regulations. Clearly, inexpensive and quick remediations are needed. This article...

Beam-Supported Slabs Subject to Edge Loading
A model is presented which allows a designer to estimate stiffnesses required to provide a given critical buckling load in beam-supported slabs subjected to biaxial edge loading, such...

Repair of The Hinckley Dam Embankments
The New York Power Authority was licensed in 1982 to construct and operate a 9 Mw hydroelectric facility at the existing Hinckley Dam near Utica, New York. Soil exploration programs undertaken...

Modern Technology in an Ancient Environment?The Answan II Power Plant
The Aswan II power plant is located at the old Low Aswan Dam in Southern Egypt. This dam was constructed in the early years of the century in order to provide irrigation water for cash...

The European Underground
Three tunneling projects in Europe are described: a tunnel bored under two rivers in Lyon, France, a subway station constructed as a mined tunnel in Vienna, Austria and a tunnel mined...

Subsurface Savings
Less conservatism than usual in designing building foundations is being accepted or demanded by some owners to save money. The article describes four examples of cost-cutting innovations,...

Cedar Falls Roller Compacted Concrete Dam
