Uncertainty in the Geologic Environment
from Theory to Practice
The state-of-the-art is presented with respect to analytical and design methods incorporating uncertainty in the geologic environment. Particular emphasis is placed on practical applications...
Sound Way to Save Fish
Fish protection need not cost an arm and a fin. Using light and sound to spare fragile blueback herring and other species a harrowing fate, the U.S. Army Corps of Engineers devised a fish...
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...
Hydraulic Design of Spillways
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 12. This manual presents guidance for the hydraulic...
Do Civil Engineers Have an Ethical Responsibility to their Client at the Expense of the Environment?
The application of engineering ethics to the environment is at the center of the debate regarding sustainable development. If the environment is to be held above client needs, say many,...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
Nonlinear Earthquake Analysis of Concrete Gravity Dams Including Sliding
The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
Tailwater Fishery Management Using a Fish Bioenergetics Model
Water releases from TVA reservoirs exert great influence on downstream water quality. Analytical tools to quantify biological response to altered environmental conditions, such as dissolved...
Changing Dam Operating Criteria to Accommodate Aquatic Biological Diversity
The Colorado squawfish, bonytail chub, humpback chub, and razorback sucker, now threatened with extinction, were once the dominant fishes in the river. Recovering these native species...
Nakajima Subsurface Dam
A new water resource is generated by a subsurface dam. This paper presents the design, construction, and monitoring of a test subsurface dam in an alluvial valley of an island for both...
Simulating Hourly Hydropower Operations for the Assessment of Environmental and Economic Impact
Generation of peaking power at Glen Canyon Dam causes river flow and stage to fluctuate on an hourly basis. This has been shown to impact the downstream physical and biological environment....
Dam Safety Issues Related to Urban Detention Ponds
Detention ponds located within or adjacent to individual residential developments provide significant benefits by improving water quality and preventing damages from floods up to the design...
Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...
Locking Into Success
In 1961, at Wheeler Lock in Alabama, crews with the Tennessee Valley Authority tried to incorporate an existing lock wall into a new cofferdam. A major portion of the land wall slid about...

Application of Fuzzy Logic in Civil Engineering in Japan
In various engineering fields, many applications of fuzzy logic have been attempted, some of which have been applied for practical use. In this paper, civil engineering applications of...
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...
