Long Term Performance Monitoring Of Shallow Slope Stabilization Utilizing Recycled Plastic Pins, Cory Alan Rauss

Civil Engineering Theses - Archive

Shallow slope failures are prevalent within the North Texas region. As highway slopes are underlain with high plastic clayey soils that experience cyclic shrinking and swelling, the soils shear strength generally decreases as the soil softens, making the soil more susceptible to sloughing and landslides. The Texas Department of Transportation (TxDOT) generally executes a rapid repair method as an economical option for repairing the slope. This method includes the failed soil removal, replacement, and recompaction to rectify the slope surface. While economical initially, this rapid repair technique may potentially prove to be costly with repeated repairs as the method does …

Dehumidification Water Quality Analysis Of The South Texas Gulf Of Mexico, Erik Esteban Castillo

Theses and Dissertations

This project is to introduce a new methodology for environmental research that analyzes humidity from a water treatment perspective. This is done by using a household dehumidifier, which extracts the excess humidity in a given space, to harvest the samples. The dehumidifier was used outside to act as an Atmospheric Water Generator (AWG), which is the process of extracting water from the atmosphere. When AWG is placed near shoreline, then it's classified as a Desalinated Atmospheric Water Generator (DAWG) since it extracts distilled seawater water-vapors. The methodology for DAWG analyzed turbidity in the humidity on SPI, indicating to meet {<.15} TCEQ turbidity water quality standard. The turbidity also showed to have an adverse relation to weather conditions. There is an open market in research on this topic, where the methodology for DAWG can offer answers. This project identifies DAWG as being a sustainable source of potable water for a municipality.
