Characterization Of Lower Rio Grande Valley Watershed, Abdulkabir O. Aduragba

Theses and Dissertations

The Lower Laguna Madre (LLM) is considered impaired because of the high concentration of bacteria and low level of dissolved oxygen (DO). LLM receives freshwater from the Lower Rio Grande Valley (LRGV) watershed. In other to understand the impairment, LRGV watershed is being studied by relying on water quality data of the contributing drainages and State resource geographic data to identify watershed boundary and pollutant sources.

The study on the North and Central LRGV watershed shows some correlation between the concentration of E. coli/Bacteria, Ammonia, Total Kjeldahl Nitrogen, Total Phosphorus, Nitrate and Nitrite, Chlorophyll-a and the sources of pollutant in …

Development Of A Cyberinfrastructure For Assessment Of The Lower Rio Grande Valley North And Central Watersheds Characteristics, Linda Isabel Navarro Navarro

Theses and Dissertations

Due to an increase in urbanization in the Lower Rio Grande Valley (LRGV), there have been substantial modifications to hydrology causing a decline in water quality to the Laguna Madre watershed. The major concern is the inflow of freshwater from the North and Central waterways released to the Lower Laguna Madre which is designated as an impaired watershed for high concentrations of bacteria and low dissolved oxygen. The objective of this study is to perform a watershed characterization to determine potential pollution sources of each watershed by developing a cyberinfrastructure and collect a wide inventory of data. The objective will …

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.
