Dam Removal In The Usa: Effects On River Water Quality, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Dam removal decisions should ideally be made after a thorough cost-benefit analysis. If dam obsolescence, structural safety, harm to fisheries, maintenance costs, and reservoir eutrophication are among the primary concerns, decommissioning would likely be favored. On the other hand, dams provide considerable benefits including water storage for agricultural and urban consumption, renewable electricity generation, support of navigational canal systems, flood control, and lakes for recreation. Because of these competing factors and interests, dam removal decision-making in the United States is often a slow process fraught with controversy, as in the case of the Klamath River.

Dams provided mechanical water power …

Using Strontium Isotopes In Conjunction With Major, And Trace Elements To Identify Water/Rock Interaction In The Upper Kittitas County, Washington, James Patterson, Carey Gazis

All Master's Theses

The complex bedrock lithologies in the Upper Kittitas County provide an ideal setting for developing isotopic methodology to identify groundwater sources and track flow paths through water-rock interaction. A wide range of 87Sr/86Sr (0.7040 to 0.7068) in surface waters, springs, and groundwater from wells was found, allowing for identification of the individual signatures of lithologic units. Rock leachates from different lithology were compared to water samples to determine a general 87Sr/86Sr signature of the water-rock interaction for that lithology. The signatures identified were systematically lower than their associated waters, but similar enough to identify the expected 87Sr/86Sr of water-rock interaction …

The Polycentric Turn: A Case Study Of Kenya's Evolving Legal Regime For Irrigation Waters, Daniel H. Cole, Stefan Carpenter, Elizabeth Baldwin

Articles by Maurer Faculty

Formal legal systems comprise a major part, but not the only part, of the “rules of the game” that structure social and social-ecological interactions. Throughout the twentieth century, centralization and consolidation of legal authority were dominant themes among many, if not all, legal systems. That process may have been successful in some cases, but in others the presumed economies of scale from consolidation and centralization either did not materialize or were offset by other social costs, including the failure to accommodate local knowledge, expertise, and preferences. In what could become a theme of the twenty-first century, many countries, including developing …

Changes In Arctic Climate And Central U.S. Weather Patterns Is There A Link?, Donald A. Wilhite, Kimberly C. Morrow, Martha Shulski

National Drought Mitigation Center: Faculty Publications

Earlier snowmelt, decreasing soil moisture, decreased corn yields, increasing extreme precipitation events—these are some of the weather effects currently observed in the central United States that might well have their origin in the rapidly warming Arctic. These and other implications of Arctic warming were among the topics discussed at a fall 2015 workshop, Implications of a Changing Arctic on Water Resources and Agriculture in the Central U.S (Wilhite and Morrow 2016).

The United States assumed chairmanship of the Arctic Council in April 2015, making the workshop topic timely. Given the importance of the Midwest and Great Plains region as a …

Drought is a recurring phenomenon in Ethiopia that significantly impacts the socioeconomic sector and various components of the environment. The overarching goal of this study is to assess the spatial and temporal patterns of meteorological drought using a satellite-derived rainfall product for the Upper Blue Nile Basin (UBN). The satellite rainfall product used in this study was selected through evaluation of five high-resolution products (Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) v2.0, Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), African Rainfall Climatology and Time-series (TARCAT) v2.0, Tropical Rainfall Measuring Mission (TRMM) and Africa Rainfall Estimate …

Assessment Of The Macroinvertebrate Assemblages From The Mesohabitats Of A Headwater Stream-Wetland Hydrologic Restoration In Eastern Kentucky, Rebecca Jo Roberts

Online Theses and Dissertations

The bulk of streams in the U.S. have been negatively impacted by anthropogenic disturbances and the streams of Kentucky are no exception. In recent decades stream restoration has become a common practice in order to improve habitat degradation resulting from land use practices such as channelization. Despite the large amount of effort and funding stream restoration projects represent, only a small portion have undergone post-restoration assessments of the ecological response in the restored streams. Slabcamp Creek, a headwater stream located in the Licking River basin in eastern Kentucky, underwent a stream-wetland hydrologic restoration in 2010 in order to improve hydrologic …

Developing A Hydrological Monitoring Program For Ponds In Wapusk National Park, Manitoba, Using Water Isotope Tracers, Stephanie Roy

Theses and Dissertations (Comprehensive)

Northern lake-rich landscapes are vulnerable to increases in surface air temperatures and are changing in dynamic ways. Current meteorological records indicate that some of the greatest warming in the past century has occurred in the Hudson Bay Lowlands (HBL). As the HBL is an extensive wetland consisting of hundreds of thousands of shallow lakes and ponds, it is difficult to anticipate the long-term implications that climate change will have on pond water balance. To develop and implement long-term monitoring of hydrological conditions, sampling of pond water isotope composition has occurred during the past six years in Wapusk National Park (WNP), …

Climate Change Adaptation For Southern California Groundwater Managers: A Case Study Of The Six Basins Aquifer, Frank Lyles

Pomona Senior Theses

Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster’s …

Evaluating The Potential Of A Geospatial/Geostatistical Methodology For Locating Rain-Derived Infiltration And Inflow Into Wastewater Treatment Systems In The Minneapolis/St. Paul Metropolitan Area, Minnesota, Usa, Vinson Aaron Williams

All Graduate Theses, Dissertations, and Other Capstone Projects

A significant issue facing municipal wastewater treatment infrastructure (WWTI) is how to manage infiltration and inflow (I/I). I/I of rain and ground water permeate into WWTI after precipitation events, periods of groundwater table rise, and percolation from surrounding surface waters. This can create discharges above the infrastructure's flow capacity, increase costs for processing the wastewater and add undesired stress to aging wastewater networks. In an attempt to assess this problem cost and time inefficient approaches have commonly been applied. This study utilizes a new and more radical methodology to try and make WWTI management more efficient. This study applies ArcGIS …

Coupling Ecological And Social Network Models To Assess “Transmission” And “Contagion” Of An Aquatic Invasive Species, Danielle Haak, Brian D. Fath, Valery E. Forbes, Dustin R. Martin, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Network analysis is used to address diverse ecological, social, economic, and epidemiological questions, but few efforts have been made to combine these field-specific analyses into interdisciplinary approaches that effectively address how complex systems are interdependent and connected to one another. Identifying and understanding these cross-boundary connections improves natural resource management and promotes proactive, rather than reactive, decisions. This research had two main objectives; first, adapt the framework and approach of infectious disease network modeling so that it may be applied to the socio-ecological problem of spreading aquatic invasive species, and second, use this new coupled model to simulate the spread …

Heavy metals, such as copper (Cu) and zinc (Zn), are considered hazardous in natural waters due to their toxicity and non-biodegradability. The focus of this study is to use batch experiments to investigate the heavy metal (Cu and Zn) removal efficiency of perlite and Earthlite^TM to improve in-situ filtration systems for stormwater catchment basins. Stormwater samples from two field sites in Portland, OR, chosen to represent a high-use commercial site and high-traffic urban road, were characterized to inform experimental design and compare to values found in literature. The Linear, Freundlich, and Langmuir isotherm models were used to describe equilibrium …

A Comparison Of Benthic Macroinvertebrate Assemblages Between Perennial And Intermittent Headwater Streams Of The Mattole River In Northern California, Usa, Mason S. London

Cal Poly Humboldt theses and projects

Intermittent streams are common throughout the world and comprise 60% or more of total river lengths in the conterminous United States. Despite their prevalence, intermittent streams are understudied, particularly first-order headwater streams, which are vital for maintaining the function, health and biotic diversity of river networks. In June 2016, I sampled five intermittent and five perennial headwater streams in the Mattole River watershed in northwestern coastal California, USA, to compare benthic macroinvertebrate (BMI) assemblages between intermittent and perennial streams. BMI samples were collected using a 500µm mesh D-net at eight randomly located riffles along a 150-m reach, and then composited, …

The Water-Electricity Nexus In California: Drought-Induced Risk To Thermal Electricity Generation, Timothy S. Hyles

Cal Poly Humboldt theses and projects

Investigating the possibility that drought might limit the water supply needed for thermal electricity generation in California, power plant water consumption data was compared to urban and agricultural consumptive demands to identify areas where power plants might contribute to regional water stress. To identify areas where power plants might be impacted by water stress, regional power plant, urban, and agricultural water demands were also compared to the available water supply. A list of power plants that would contribute most to regional water scarcity (individually and in aggregate) was highlighted, based on the plant’s water consumption volume, water-intensity, and water source. …

Sedimentation And Erosion Patterns Within Anabranching Channels In A Lowland River Restoration Project, Ivan Medel

Cal Poly Humboldt theses and projects

Phase 2A of the Salt River Ecosystem Restoration Project (SRERP) was implemented to increase transport efficiency of water and sediment through a low gradient river reach to alleviate flooding on adjacent properties. The SRERP utilizes a unique anabranching channel design that concentrates base flows within a single deep, narrow channel overflowing onto an alternating series of higher elevation active benches at flood stages. This paper investigated the performance of the project’s hydraulic conveyance and general utility of anabranching channels as a restoration alternative by assessing the distribution and magnitude of deposition and erosion response patterns.

Environmental Emission Of Pharmaceuticals From Wastewater Treatment Plants In The Usa, Bikram Subedi, Bommanna G. Loganathan

Faculty & Staff Research and Creative Activity

The residual drugs, drug bioconjugates, and their metabolites, mostly from human and veterinary usage, are routinely flushed down the drain, and enter wastewater treatment plants (WWTP). Increasing population, excessive use of allopathic medicine, continual introduction of novel drugs, and existing inefficient wastewater treatment processes result in the discharge of large volumes of pharmaceuticals and their metabolites from the WWTPs into the environment. The effluent from the WWTPs globally contaminate ~25% of rivers and the lakes. Pharmaceuticals in the environment, as contaminants of emerging concerns, behave as pseudo-persistent despite their relatively short environmental half-lives in the environment. Therefore, residual levels of …
