Development of a Wetland/Riparian Resource Model for the Missouri River System
Wetlands and riparian areas are significant resources along the Missouri River, providing important fish and wildlife habitat. These resources required evaluation as part of the review...
Development of Environmental Impacts Model for Missouri River System
The Corp of Engineers is reviewing the Missouri River Master Water Control Manual with the goal of determining the best plan for the Missouri River Basin. The Environmental Impacts Model...
An Interactive Regional Regression Approach to Estimating Flood Quantiles
In Texas, a computer program has been developed which will estimate flood quantiles for an ungaged site based on data from gaging stations with similar watershed characteristics. The user...
Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...
Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....
Intelligent Design and Remediation of Shallow Landfill Burial Systems
The SLEUTH (Shallow Landfill Evaluation Using Transport and Hydrology) prototype decision support system (DSS) has been developed for design and remediation of shallow landfill burial...
Design of Clay Liner Permeability at Laboratory Scale Using Expert Systems
Unlike other soil properties, permeability of compacted clay is highly variable. The large number of parameters that affect permeability of compacted clay renders permeability unpredictable...
Quality Management of Earthwork Using Knowledge-based Systems
Earthwork is an integral part of many construction projects. It involves cleaning of the site, loading and spreading of soil, and soil compaction and leveling. Heterogeneous orientation...
Circulation and Flushing in Casco Bay, Maine
A modified 3-D hydrodynamic numerical model MECCA (Model for Estuarine and Coastal Circulation Assessment; Hess, 1989) has been applied to Casco Bay, Maine, with a horizontal resolution...
Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...
Vertical and Horizontal Deformations for Foundations on Sand: An Experimental Study
A natural scale model is used in order to investigate experimentally the sand soil deformation behavior which accepts loads by shallow foundations. The vertical and horizontal soil displacements...
Uplift Load-Displacement Behavior of Grillage Foundations
Full-scale field tests were conducted on steel grillage foundations for lattice transmission line towers that had been in place since 1929, 1947, and 1958. A total of eight tests were...
A Case History of Settlement of an Embankment on Lagoonal Deposits Influenced by Artesian Conditions
A geotechnical engineering investigation was performed for the Pearl Kai Center, a shopping center in the Pearl Harbor area of the island of Oahu, Hawaii. The proposed commercial development...
Towards a Rational Method of Predicting Settlements of Spread Footings on Sand
Prediction of settlements of both large and small spread footings on sand has traditionally been carried out using methods which are largely empirical. In recent years, advances have been...
An Alternative Formulation of Volume-change Behavior of Soils
The traditional approach based on the semi-logarithmic representation of volume change data is known to work relatively well for prediction of ground settlements. This approach has been...
Cyclic Loading for the Measuring of Soil Consolidation Parameters
A method of determination of soil consolidation characteristics using sinusoidal loading is described. It can be performed in laboratory test or in situ observation as well, with different...
Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...
Application of the Diflupress L.D. Field Test to Settlement Calculation
Electricite de France developed a new in situ measurement apparatus (Diflupress L.D.) in order to predict the delayed settlements that can appear under heavy constructions. From the experimental...
The Behavior of a Building with Shallow Foundations on a Stiff Lateritic Clay
The use of shallow foundations for buildings in Sao Paulo, either on soils of the Tertiary Sedimentary Basin of Sao Paulo (TSBSP) or on those of saprolitic origin is not as frequent as...
Residual Soil Settlment Related to the Weathering Profile
Residual soils are the in-place residue from rock weathering. They differ greatly from the better understood deposited soils in that their particle arrangements and mineralogy reflect...
