Streamflow Modeling Of Johnson Creek Subwatersheds Using The Precipitation Runoff Modeling System, Theophilus Matthew Malone

Civil and Environmental Engineering Master's Project Reports

Johnson Creek, in the Portland, Oregon metropolitan region, has several pollutants on the U.S. Environmental Protection Agency's (EPA) 303(d) list including excess heat, low dissolved oxygen, and harmful bacteria. Understanding streamflow response to precipitation events is an important component to evaluating water quality trends and calculating the Total Maximum Daily Load (TMDL) for pollutants of concern. Investigating the streamflow-precipitation relationship on the subwatershed scale can give insight to the hydrologic response of a given watershed. However, developing rating curves for several subwatersheds can be cost and time prohibitive. The objective of this project was to develop a hydrologic model using …

Lead (Pb) Contamination Of Water Drawn From Pitcher Pumps In Eastern Madagascar, David Bradlee Akers

USF Tampa Graduate Theses and Dissertations

Access to safe water supply--a major determinant of public health--is less than 50% in Madagascar, and access to piped, treated water remains out of reach financially for many in the urban and peri-urban areas where available. The Self-supply option of the Pitcher Pump has been meeting the need for household water in coastal areas of Madagascar since the early 1960s and has proven a sustainable option for many. These pumps make use of leaded components in the construction, however, which may pose a health risk for heavy metal intoxication and therefore cause the water to be unsafe for drinking and …

Agenda: Fracking, Water Quality And Public Health: Examining Current Laws And Regulations, Network For Public Health Law, American Society Of Law, Medicine & Ethics, Public Health Law Research Program

Fracking, Water Quality and Public Health: Examining Current Laws and Regulations (March 20)

Improved technology developments in directional drilling and hydraulic fracturing, more commonly known as "fracking," have resulted in an oil and gas production boom nationwide. Fracking involves pumping pressurized water, sand, and chemicals down wells to crack bedrock, freeing petroleum and natural gas. Wastewater discharges, hydraulic fracturing fluid releases, and other accidental spills pose potential water quality risks, sparking concern for public health.

This webinar will examine the laws and regulations governing water quality issues related to fracking, recent state court decisions affecting regulations, and implications for public health.

Lifeblood Of The Earth: Nuwuvi (Southern Paiute) Hydrological Knowledge And Perceptions Of Restoration In Two Southern Nevada Protected Areas, Kendra Lesley Wendel

Dissertations and Theses

In the arid landscapes of the southern Great Basin and northern Mojave Desert, issues surrounding water resource management are often politically contentious. Nuwuvi (Southern Paiute) have known and managed these resources for thousands of years prior to Euro-American arrival in the region. A variety of factors, including federal policies that resulted in the creation of reservations and forced placement in boarding schools, as well as contemporary resource commodification, have influenced Nuwuvi knowledge and practice.

In this thesis, I examined the character of Nuwuvi ethnohydrological knowledge, including management knowledge, of two protected areas: Spring Mountains National Recreation Area (SMNRA), managed by …

Agriculture, Environmental Restoration And Ecosystem Services: Assessing The Costs Of Water Storage On Agricultural Lands In South Florida, Kayla Ouellette

USF Tampa Graduate Theses and Dissertations

A large part of the environmental restoration required by the Comprehensive Everglades Restoration Plan calls for more water-storage on lands south of Lake Okeechobee in order to restore the natural water flows of the Everglades watershed. The Everglades Agricultural Area (EAA) can be used for increased water storage in order to relieve coastal estuaries of excess water in the rainy season. This water storage can deliver additional ecosystem services of soil retention and reduced CO2 emissions that could compensate farmers for the cost of water storage by increasing long term farm profitability. The goals of this study were 1) to …

Similar Resilience Attributes In Lakes With Different Management Practices, Didier L. Baho, Stina Drakare, Richard K. Johnson, Craig R. Allen, David G. Angeler

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Liming has been used extensively in Scandinavia and elsewhere since the 1970s to counteract the negative effects of acidification. Communities in limed lakes usually return to acidified conditions once liming is discontinued, suggesting that liming is unlikely to shift acidified lakes to a state equivalent to pre-acidification conditions that requires no further management intervention. While this suggests a low resilience of limed lakes, attributes that confer resilience have not been assessed, limiting our understanding of the efficiency of costly management programs. In this study, we assessed community metrics (diversity, richness, evenness, biovolume), multivariate community structure and the relative resilience of …

Groundwater Flow Across Spatial Scales: Importance For Climate Modeling, Nir Krakauer, Haibin Li, Ying Fan

Publications and Research

Current regional and global climate models generally do not represent groundwater flow between grid cells as a component of the water budget. We estimate the magnitude of between cell groundwater flow as a function of grid cell size by aggregating results from a numerical model of equilibrium groundwater flow run and validated globally. We find that over a broad range of cell sizes spanning that of state of the art regional and global climate models, mean between cell groundwater flow magnitudes scale with the reciprocal of grid cell length. We also derive this scaling a priori from a simple statistical …

Examining Potential Residential Participation In Financial Incentives To Mitigate Impervious Surface Effects In Howard County, Maryland, Kristin M. Larson, Jim Caldwell, Alexander Cloninger

Suburban Sustainability

Maryland passed legislation to reduce impervious surface effects and stormwater runoff by mandating a remediation fee for ten of its counties. Along with the fee, mandated counties may use funds generated to encourage residents to follow stormwater Best Management Practices (BMPs). This study uses Maryland's Howard County as a case study to examine the potential participation of its residents in financial incentives for the BMPs of rain gardens, cisterns, and permeable pavers. A survey was issued to gauge potential participation of homeowners (n=110), and results were then compared to participation numbers in three similar already implemented financial incentive programs. Results …

Diverted Opportunity: Inequality And What The Southnorth Water Transfer Project Really Means For China, Britt Crow-Miller

Institute for Sustainable Solutions Publications and Presentations

The article discusses China’s South-North Water Transfer Project (SNWTP) and argues that not only does the SNWTP reflect existing spatially articulated power discrepancies, but it reinforces and potentially exacerbates those inequalities by prioritizing Beijing’s present and future water needs above those of its neighbors and locking them in place for decades to come. Smaller, regional cities and rural areas — Shijiazhuang and Baoding in Hebei, Nanyang in Henan and the gritty, struggling towns and villages around Danjiangkou Reservoir — might have gained muchneeded jobs and government investment in the short term around the construction of the Middle Route, but without …

Riparian Vegetation Assemblages And Associated Landscape Factors Across An Urbanizing Metropolitan Area, Christa Von Behren, Andrew Evans Dietrich, J. Alan Yeakley

Environmental Science and Management Faculty Publications and Presentations

While diverse, native riparian vegetation provides important functions, it remains unclear to what extent these assemblages can persist in urban areas, and under what conditions. We characterized forested riparian vegetation communities across an urbanizing metropolitan area and examined their relationships with surrounding land cover. We hypothesized that native and hydrophilic species assemblages would correlate with forest cover in the landscape. For each of 30 sites in the Portland–Vancouver metro area, we recorded vegetation at 1-cm intervals along 3 transects using the line-intercept method. Land cover was characterized at 2 scales: within 500 m of each site and across the entire …

Phenotypic Plasticity Of Invasive Spartina Densiflora (Poaceae) Along A Broad Latitudinal Gradient On The Pacific Coast Of North America, Jesus M. Castillo, Brenda J. Grewall, Andrea Pickart, Alejandro Bortolus, Carlos Pena, Enrique Figueroa, Mark D. Sytsma

Environmental Science and Management Faculty Publications and Presentations

Premise of the study: Phenotypic acclimation of individual plants and genetic differentiation by natural selection within invasive populations are two potential mechanisms that may confer fitness advantages and allow plants to cope with environmental variation. The invasion of Spartina densiflora across a wide latitudinal gradient from California (USA) to British Columbia (Canada) provides a natural model system to study the potential mechanisms underlying the response of invasive populations to substantial variation in climate and other environmental variables.

Methods: We examined morphological and physiological leaf traits of Spartina densiflora plants in populations from invaded estuarine sites across broad latitudinal and climate …

Water Movement Through The Unsaturated Zone Of The High Plains Aquifer In The Central Platte Natural Resources District, Nebraska, 2008-12, Gregory V. Steele, Jason J. Gurdak, Christopher M. Hobza

United States Geological Survey: Water Reports and Publications

Uncertainty about the effects of land use and climate on water movement in the unsaturated zone and on groundwater recharge rates can lead to uncertainty in water budgets used for groundwater-flow models. To better understand these effects, a cooperative study between the United States Geological Survey (USGS) and the Central Platte Natural Resources District (CP NRD) was initiated in 2007 to determine field-based estimates of recharge rates in selected land-use areas of the CP NRD in Nebraska. Measured total water potential and unsaturated-zone profiles of tritium, chloride, nitrate as nitrogen, and bromide, along with groundwater-age dates, were used to evaluate …

Earth's surface is rapidly urbanizing, resulting in dramatic changes in the abundance, distribution and character of surface water features in urban landscapes. However,the scope and consequences of surface water redistribution at broad spatialscales are not well understood. We hypothesized that urbanization would lead to convergent surface water abundance and distribution: in other words, cities will gain or lose water such that they become more similar to each other than are their surrounding natural landscapes. Using a database of more than 1 million water bodies and 1 million km of streams, we compared the surface water of 100 US cities with …

Are Climate Model Simulations Useful For Forecasting Precipitation Trends? Hindcast And Synthetic-Data Experiments, Nir Y. Krakauer, Balázs M. Fekete

Publications and Research

Water scientists and managers currently face the question of whether trends in climate variables that affect water supplies and hazards can be anticipated. We investigate to what extent climate model simulations may provide accurate forecasts of future hydrologic nonstationarity in the form of changes in precipitation amount. We compare gridded station observations (GPCC Full Data Product, 1901–2010) and climate model outputs (CMIP5 Historical and RCP8.5 simulations, 1901–2100) in real and syntheticdata hindcast experiments. The hindcast experiments show that imputing precipitation trends based on the climate model mean reduced the root mean square error of precipitation trend estimates for 1961–2010 by …

Use Of Nanoparticles In Disinfection Of Desalinated Water In United Arab Emirates, Laila Masoud Rashid Al-Issai

Theses

United Arab Emirates (UAE) as well as most Gulf Countries depends mostly on desalinated sea water as the main source of drinking water. The drinking water disinfection process has been routinely carried out since the turn of the century to destroy pathogenic organisms and prevent waterborne diseases. When chemical disinfection is applied before or after desalination, a number of harmful compounds are formed posing potential risks to the health of human or aesthetic quality of drinking water. As such, a tremendous number of studies have been conducted to identify new alternative methods of disinfecting water without formation of harmful Disinfection …

Neither zebra nor quagga mussels (Dreissena polymorpha and D. rostriformis bugensis, respectively) were detected by Portland State University (PSU) during their early detection sampling in Oregon water bodies during 2013. PSU conducted sampling for planktonic larvae, juvenile, and adult mussels at nine Oregon water bodies during the July to August period coinciding with water temperatures favorable for mussel spawning. A total of 113 plankton samples were collected and over 1.6 million liters of lake water were filtered through 63-μm mesh nets during plankton sample collection. The greatest sampling effort occurred in East Lake, Prineville Reservoir, and Paulina Lake; these water …
