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...

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...
Geosynthetics in Dam Rehabilitation
In the first part of this paper, a review of the various types of geosynthetics is presented and it is indicated that all types of geosynthetics have been or can be used in dams to perform...
Landslide Stabilisation at the Clyde Power Project, New Zealand
The Clyde Power Project is a hydro electric development on the Clutha River in the South Island of New Zealand. A wide range of stabilization measures have been used to treat several large...
Improving Dam Safety Using a Fin Drain
Bloemhoek Dam is an embankment dam with a maximum height of 21 m, which leaked severely after first filling in 1978. This leakage resulted in the development of `boils' over a portion...
The Douglas Dam Emergency Response and Rehabilitation
Through the timely response of the Owner, the potential failure of Douglas Dam was averted, and lives and property downstream were protected. The economic losses created by loss of irrigation...
Remedial Works at Troneras and Miraflores Dams in Colombia
The 38 m high Troneras and the 55 m high Miraflores earth dams were built in the period 1959-1965. The dams are composed of residual soils and founded on a deep residual overburden. Significant...
Rehabilitation of a Toe Drain
Old or improperly designed toe drains can cause trouble for embankment dams. Toe drains installed without proper filtering can provide an easy course for internal erosion and piping of...
General Design and Construction Considerations for Remedial Seepage Control
All earth and rock-fill dams are subject to seepage through the embankment, foundation and abutments. Methods for remedial seepage control include storage restriction, grouting, upstream...
A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...
Storm Water Utility Experience in Bellevue, Washington
Surface water management is seen as a flood protector by most, a savior of the environment by some and a subversion of property rights by others. As recently as 20 years ago, there were...
Cross Section 90's?A Profile of User Fee Funded Stormwater Utility Practices in the U.S.
The task of securing adequate tax funding to support a stormwater drainage system regarding operating and capital needs is discussed. An innovative and practical solution was arrived at;...
Expert System for the Preloading Method of Ground Improvement
Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...
Hydrologic Recovery of Artificially-Drained Wetlands in Coastal North Carolina
The hydrologic status of three peat wetland areas was compared to test a theoretical model which suggests that loss of conveyance capacity in artificial channels allows wetlands to restore...
The Dynamic Geomorphology of Yangpu Bay, Hainan Island, China
Yangpu Bay is located in the northwest of Hainan Island. It consists of Yangpu Bay (outer bay) and Xinying Bay (inner bay). During 1983-1989, we carried out a series of research into the...
Short-Term Effects of the Banjul Sewerage and Drainage Project on Faecal Coliform Counts
Assessment of the short-term effects of the Banjul sewerage and drainage project on faecal coliforms (indicator organisms for contamination of pathogens) in the coastal areas. The project...
Characteristic of the Yellow River Delta
The yellow river delta is a most unstable delta in the world. The river burst its lowstream bank 1500 times during the last 3000 years, 26 large shifting of the channel as well. The river...
The Use of a Flood Damage Rating System to Aid Urban Stormwater Management
Increasing urbanisation and the subsequent decrease in natural storage and infiltration potential in a catchment, cause increased runoff peaks and volumes. Existing stormwater drainage...
Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...
