Three Dams, One Reservoir
The three dams that make up the 800,000 acre-ft (987 million m�) Eastside Reservoir in Riverside County, California, required extensive foundation excavation and careful placement of embankment...
Moving Mountains
The earthmoving and rock-crushing operations at the Eastside Reservoir represented one of the largest such projects in the history of the United States. The earth and rock-fill dams required...
Added Protection
The U.S. Bureau of Reclamation is modifying the 335 ft (102 m) high Casitas Dam in Ventura County, California, to withstand a magnitude 6.9 earthquake. The modification includes strengthening...
Safeguarding Los Alamos
A forest fire that burned 48,000 ac (19,500 ha) around the Los Alamos National Laboratory, in New Mexico, in May 2000, created another problem for one of the nation's most...
Instrumentation of Embankment Dams and Levees

Recycling Penn Forest Dam
Almost since it's construction more than 30 years ago, the Penn Forest Dam had suffered severe seepage, leading officials in Bethlehem, Penn., to wonder how secure their largest...
Santa Ana River Mainstem Project
The Santa Ana River Mainstem Project consists of seven major features including the construction of 550 ft. high earth and rockf ill dam; raising the embankment by 28 feet of Prado Dam,...
Asphalt-Concrete Water Barriers for Embankment Dams
Because of its simplicity in design and construction, the asphalt concrete core is rapidly becoming the water barrier of choice for embankment dams in many parts of the world. This is...
Wanapum Dam Embankment Settlement Study
This paper discusses the long term vertical movements of a zoned earth embankment. Vertical movement of the Wanapum Dam embankment has been monitored since its completion in 1964. The...
Analysis of the Juturnaiba Embankment Dam Built on an Organic Soft Clay
The Juturnaiba Dam, located in the northern part of Rio de Janeiro State, Brazil, has 1.2 km of its length built on an organic soft clay about four meters deep. The construction of the...
Performance of Nanhua Dam During Construction
The pore pressure response and settlement during the construction of Nanhua dam were studied by several methods, including Hilf's method, laboratory stress path simulation and numerical...
Dynamic Compaction of Landfill Beneath Embankment
This paper presents the results of a highway project where dynamic compaction was used to densify a closed landfill prior to constructing highway embankments over the landfill. The purpose...
A Procedure for Predicting Seismic Deformation of Earth Structures
This paper presents an analysis procedure for predicting the earthquake induced displacements of earth structures. The procedure is an extension of the simple Newmark method from a single-degree-of-freedom...
New Methods for Modelling Dam-Break Wave
Recent developments in numerical analysis for hyperbolic equations have led to new methods which solve shallow water equations including complementary equations for hydraulic jumps. An...
Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...
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...
Jatiluhur Dam: Problems and Rehabilitation
The Jatiluhur Dam in Indonesia, completed in 1965, is an innovative design consisting of rockfill embankment with a clay core and a vertical cylindrical Intake Spillway. Within the Intake...
Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...
