Estimation of E. coli Concentrations from Failing On-Site Wastewater Treatment Facilities (OWTS) Using GIS
(2014-08-12)
Failing Onsite Wastewater Treatment Systems (OWTSs) have been identified as a significant threat to water quality, discharging significant amounts of inadequately treated sewage effluents. When developing a Watershed ...
Impervious Areas: Examining the Undermining Effects on Surface Water Quality
(2012-02-14)
This study explored the relationship between increased proportions of imperviousness in a watershed on surface water quality and examined the effectiveness of using remote sensing to systematically and accurately determine ...
Original Texas Land Survey as a Source for Pre-European Settlement Vegetation Mapping
(2012-02-14)
