Evaluating Alternatives For Augmented Water Quality Improvement Utilizing Oyster Restoration As Best Management Practice (Bmp), Stephanie Roberts Long Apr 2013

Evaluating Alternatives For Augmented Water Quality Improvement Utilizing Oyster Restoration As Best Management Practice (Bmp), Stephanie Roberts Long

Civil & Environmental Engineering Theses & Dissertations

Due to several anthropogenic influences, the Chesapeake Bay has experienced a marked decrease in water quality since the colonists arrived at the Jamestown settlement in Virginia during the 1600s. Higher concentrations of nitrogen and phosphorus have enriched the estuaries and coastal waters via point sources (sewage treatment plants and industrial wastes), nonpoint sources (agricultural run-off and septic tank discharges) and the atmosphere (Newell et al., 2005). Restoring oyster beds is considered a Best Management Practice (BMP) to improve water quality as well as provide physical habitat for aquatic species and a healthier estuarine system (USACE Native Oyster Restoration Master …


Rare Plant Associations, Oregon Dunes National Recreation Area, Sutton Recreation Area, And Heceta Sand Dunes Acec/Ona, John A. Christy Apr 2013

Rare Plant Associations, Oregon Dunes National Recreation Area, Sutton Recreation Area, And Heceta Sand Dunes Acec/Ona, John A. Christy

Institute for Natural Resources Publications

Nine of the ten rare plant associations identified in the dunes in 1993 are recommended for continued inclusion in conservation planning. Large-patch associations are currently in good condition, but small-patch associations are being infilled by a combination of plant succession and invasive species. Repeat photography using aerial and ground-based imagery is recommended as a way to gauge the rate of change in dune communities. Prescribed fire is recommended to monitor rejuvenation effects on two shore pine woodland associations that are most at risk of infilling. Vegetation mapping based on remote sensing will enable more accurate assessment of vegetation features, and …

Map-Based Probabilistic Infinite Slope Analysis Of The Stephens Creek Watershed, Portland, Oregon, Ryan Andrew Cole Mar 2013

Map-Based Probabilistic Infinite Slope Analysis Of The Stephens Creek Watershed, Portland, Oregon, Ryan Andrew Cole

Dissertations and Theses

The Stephens Creek Watershed in southwest Portland, Oregon was chosen by the city as a pilot project for urban stream restoration efforts, and the infiltration of stormwater was identified as a potential restoration strategy. The Stephens Creek Watershed has historically been known to be unstable during high precipitation events (Burns, 1996), and the need to address the response of slope stability to anthropogenically-driven changing groundwater conditions is the focus of this study. Airborne light detection and ranging (LiDAR) and geotechnical data from the City of Portland were employed to create a high resolution (0.84 m2) physics-based probabilistic slope stability model …

Modeling Vulnerability Of Groundwater To Pollution Under Future Scenarios Of Climate Change And Biofuels-Related Land Use Change: A Case Study In North Dakota, Usa, Ruopu Li, James W. Merchant

School of Natural Resources: Faculty Publications

Modeling groundwater vulnerability to pollution is critical for implementing programs to protect groundwater quality.Most groundwater vulnerability modeling has been based on current hydrogeology and land use condi- tions. However, groundwater vulnerability is strongly dependent on factors such as depth-to-water, recharge and land use conditions thatmay change in response to future changes in climate and/or socio-economic condi- tions. In this research, a modeling framework, which employs three sets of models linked within a geographic information system (GIS) environment, was used to evaluate groundwater pollution risks under future climate and land use changes in North Dakota. The results showed that areas with …

Csp Desalination/Water Purification Unit, Sean Goodison

Industrial Technology and Packaging

An estimated 3.4 million people die each year from unsanitary water or inaccessible water supply. Most of these deaths take place in the developing, third world (99%). There is a dilemma arising on the world stage as well. The water demand/supply deficit is expected to increase significantly over the next 37 years if preemptive action isn’t taken. 97% of the world water supply is oceanic, making it an attractive solution to the water deficit. Providing autonomous, “deploy and watch” systems for utilizing sustainable energy to provide purified water for unitized low pricing has the potential to penetrate a large world …

National Drought Mitigation Center: Faculty Publications

Comparison of multiple hydrologic indicators, derived from independent data sources and modeling approaches, may improve confidence in signals of emerging drought, particularly during periods of rapid onset. This paper compares the evaporative stress index (ESI)—a diagnostic fast-response indicator describing evapotranspiration (ET) deficits derived within a thermal remote sensing energy balance framework—with prognostic estimates of soil moisture (SM), ET, and runoff anomalies generated with the North American Land Data Assimilation System (NLDAS). Widely used empirical indices based on thermal remote sensing [vegetation health index (VHI)] and precipitation percentiles [standardized precipitation index (SPI)] were also included to assess relative performance. Spatial and …

Potential Water Quality Impacts Originating From Land Burial Of Cattle Carcasses, Qi Yuan, Daniel D. Snow, Shannon L. Bartelt-Hunt Jan 2013

Potential Water Quality Impacts Originating From Land Burial Of Cattle Carcasses, Qi Yuan, Daniel D. Snow, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

Among the conventional disposal methods for livestock mortalities, on‐farm burial is a preferred method, but the potential water quality impacts of animal carcass burial is not well understood. Typically, on‐farm burial pits are constructed without liners to prevent percolation of leachate into soil and groundwater. To date, no information is available on temporal trends for contaminants in leachate produced from livestock mortality pits. In our study, we examined the concentrations of conventional contaminants (electrical conductivity, COD, TOC, TKN, TP, and solids) as well as some antimicrobials and steroid hormones for a period of 20 months. High concentrations of conventional contaminants …

Surface Energy Balance Model Of Transpiration From Variable Canopy Cover And Evaporation From Residue-Covered Or Bare Soil Systems: Model Evaluation, Luis Octavio Lagos, Derrel Martin, Shashi B. Verma, Suat Irmak, Ayse Kilic, Dean E. Eisenhauer, Andrew E. Suyker

School of Natural Resources: Faculty Publications

A surface energy balance model (SEB) was extended by Lagos et al. Irrig Sci 28:51–64 (2009) to estimate evapotranspiration (ET) from variable canopy cover and evaporation from residue-covered or bare soil systems. The model estimates latent, sensible, and soil heat fluxes and provides a method to partition evapotranspiration into soil/residue evaporation and plant transpiration. The objective of this work was to perform a sensitivity analysis of model parameters and evaluate the performance of the proposed model to estimate ET during the growing and non-growing season of maize (Zea Mays L.) and soybeans (Glycine max) in eastern …
