An investigation of the feasibility of a cutbank slope design method based on the analysis of natural slopes

Creator:: Keener, Quentin Roosevelt
Abstract:: The failure of cutbanks is a major problem encountered by those who construct low-cost roads in naturally forested residual soils. Attempts have been made to lessen the severity of failures by classifying certain soil areas as to their susceptibility to failure, in addition to bringing past design experience into play...

The characterization and physical-chemical treatability of log pond waters

Creator:: Blanton, Guy Ivan
Abstract:: The treatability of waters from four log ponds in Oregon by physical and chemical treatment methods was investigated. Treatment processes included sand filtration, activated carbon contact and coagulation with aluminum sulfate. Preliminary studies were made at each log pond to determine the homogeneity of the pond water for sampling purposes...

The performance of drivers with physical limitations at T-intersections

Creator:: Hunter-Zaworski, Katharine M.
Abstract:: The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:: Michalsen, Mandy M.
Abstract:: Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

Effect of an Idealized Mangrove Forest of Moderate Cross-shore Width on Loads Measured on a Sheltered Structure and Comparison with Predicted Forces

Creator:: Mitchell, William T.
Abstract:: As coastal communities face increasing chronic and acute hazards, nature-based coastal engineering solutions have experienced a rapid growth in popularity and interest. Recent works on this topic have shown that “Green Infrastructure” may be effective at mitigating coastal hazards and therefore provide sustainable adaptation alternatives to traditional engineering solutions such...

Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

Creator:: Hosseini, Parnian
Abstract:: Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...

Hydraulic functions of soils from physical experiments and their applications

Creator:: Su, Charles
Abstract:: Based upon the Pearson Type VIII distribution function, a general retention function which relates the saturation to the capillary pressure in disturbed soils has been discovered. This simple and yet complete function has been shown to describe precisely the imbibition as well as the drainage branch of the retention curve....

A review of research on shear and diagonal tension in reinforced concrete beam

Creator:: Yang, Jui-Tsung
Abstract:: Resistance of reinforced concrete beams to diagonal tension was studied in a series of papers which included beams without web reinforcement and beams with various types of web reinforcement. The magnitude of the loading causing the formation of initial diagonal tension cracks depended primarily on the dimensions of the cross...

Review of guidelines for the design of tsunami vertical evacuation buildings

Creator:: Cawley, Jessica Grace
Abstract:: Tsunamis have the potential to inflict severe damage and loss of life in coastal communities. Structures known as vertical evacuation buildings provide an alternative evacuation site for communities living in relatively flat, coastal regions with inadequate sources of high ground for evacuation. Design of these structures balances risk and economy,...
