Environmental Degradation of Spawning Gravels in the Tucannon River
The important relationship between upstream soil and water conservation measures and salmonid habitat conditions in the Pacific Northwest is illustrated by way of computer simulations...
Water Quality Modeling Using a Small Watershed Model (SWAM)
The Small Watershed Model (SWAM) is a state-of-the-art model that simulates the movement of water, sediment, and chemicals through a small, mixed-land-use watershed. It was developed to...
Analytical Studies of the Schoharie Bridge Failure
Analytical studies consisted of geomorphic, hydrologic, hydraulic, and erosion analyses including mathematical modeling with HEC-1 and WSPRO, the new FHWA water-surface profile model....
Reliability of Compacted Soil Liners
Determination of transport times of contaminants through a soil liner is hindered by the inherent spatial variability of the hydraulic conductivity of compacted soil. The existence of...
Estimation of Uplift Pressure in Cracks in Concrete Gravity Dams
This paper presents an analytical solution to predict uplift pressures in cracks in concrete gravity dams. It is shown that drainage systems are effective in reducing such pressures....
Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...
Application of Reservoir Sedimentation Data to Problems of Environmental Management
Application of sediment delivery ratios and sediment routing procedures to sediment measurements provide an alternative approach to the prediction of localized average annual erosion rates....
Generation of Native FE in Lunar Soil
Electron Spin Resonance (ESR) studies on lunar samples produced some unexpected results which led to recognition of the presence of abundant single-domain Feo...
Hot Pressing of Lunar Soil and Qualification for Manned Applications
Lunar soil may be fabricated into useful building materials analogous to those used for masonry, concrete and ceramic pipe applications on earth. The process has been analyzed theoretically...
Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...
Sulfur-Based Construction Materials for Lunar Construction
Several approaches have been suggested to use lunar or Martian aggregate in extraterrestrial construction. These approaches include hot pressing of lunar soils producing cements and concretes...
The Physics of Sediment Transport by Wind and Water
Sponsored by a special projects committee under the guidance of the Sedimentation Technical Committee of ASCE. This collection contains noteworthy,...
Pipeline Infrastructure
These proceedings include papers which cover the topics of innovative pipeline design, condition monitoring, soil-pipe interaction, inspection, maintenance, and rehabilitation. These collective...
Earthquake Engineering and Soil Dynamics II?Recent Advances in Ground-Motion Evaluation
Ground-motion determination for analysis and design of engineering structures is a shared, interdisciplinary task involving geologists, seismologists, geophysicists, geotechnical engineers,...
Transit Triumph
The 1988 Outstanding Civil Engineering Achievement is Boston's Southwest Corridor, chosen not only for its size, complexity and technology, but for its environmental, public...
Air Power Boosts Utility Energy Supplies
Based in part on successful findings of tests, in which compressed air was stored in underground aquifers, Central Illinois Public Service engineers are investigating a type of pumped...
Recognizing Liquefaction Hazard
Technique for assessing liquefaction hazard are considered herein: Methods for compiling regional opportunity maps are reviewed and a crude national map is developed. Compilation of regional...
Mitigation of Seismic Effects on Water Systems
Historically, earthquakes have caused damage to water systems. In this paper, water system facilities at risk due to seismic activity as well as potential damage mechanisms are identified....
Hydraulic Fill Structures
This volume contains 53 papers covering many aspects of hydraulic fill structures with special emphasis on geotechnical issues. The papers present an excellent review of historical development,...
Geosynthetics: Cleanup Tools
In addition to their use in liners and drainage systems for new landfills, geosynthetics can be used in environmental remediation projects. In an early example, contaminated muck was removed...
