Hydrologic Modeling To Examine Land Use Change Impacts (1970’S And 2005) On The Sediment Yield And Flow Regime In Cayuga Creek, Niagara County, New York, Kimly Reth

Multidisciplinary Studies Theses

This research aims to assess the water quality and the land use change impacts on sediment concentration and flow regime in Cayuga Creek, Niagara County, NY for two land use periods, 1970’s and 2005. The 1970’s land use, classified by the USGS, had a significant error. Therefore, the scenario of sediment yield and discharge level to land use change is more of a “what if” since the 1970’s land use was classified incorrectly. The Soil and Water Assessment Tool (SWAT)was used to simulate flows and sediment concentrations for the two land use scenarios using the same rainfall data at the …

Water Security And Management In Burkina Faso: How Socio-Political And Cultural Complexities Affect Development, Megan M. Godfrey

Independent Study Project (ISP) Collection

Burkina Faso is currently ranked as the 175^th poorest country out of 177. In addition to over 50% of the population living in poverty, Burkina Faso is challenged with droughts and lack of adequate water system infrastructure. The agricultural nation is dependent on water to grow and harvest crops, as almost 80% of the farming done in the nation is for sustenance. This paper will address the role culture plays in water systems; how gender relations, and cultural practices influence water management and sanitation systems. In addition, this paper will examine how current systems in place are changing and …

Estimating Annual Precipitation For The Colorado River Basin Using Oceanic-Atmospheric Oscillations, Ajay Kalra, Sajjad Ahmad

Civil and Environmental Engineering and Construction Faculty Research

Estimating long-lead time precipitation under the stress of increased climatic variability is a challenging task in the field of hydrology. A modified Support Vector Machine (SVM) based framework is proposed to estimate annual precipitation using oceanic-atmospheric oscillations. Oceanic-atmospheric oscillations, consisting of Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO), Atlantic Multidecadal Oscillation (AMO), and El Niño–Southern Oscillation (ENSO) for a period of 1900–2008, are used to generate annual precipitation estimates with a 1 year lead time. The SVM model is applied to 17 climate divisions encompassing the Colorado River Basin in the western United States. The overall results revealed that …

Assessment Of The Oxbow Morphology Of The Caloosahatchee River And Its Evolution Over Time: A Case Study In South Florida, Chloe Delhomme

USF Tampa Graduate Theses and Dissertations

The Caloosahatchee River, located in Southern Florida, was originally a meandering and relatively shallow river. During the 1920s, the Caloosahatchee River was channelized and became the C-43 canal. The channelization has significantly impacted the river ecosystem, particularly the oxbows. The oxbows are the U-shaped water bodies on each side of the river channel, which are the remnant bends of the original river. To understand how anthropogenic influence affects hydrologic systems, the proposed case study was designed to assess the geomorphic changes of the oxbows of the Caloosahatchee River, Florida. Understanding and documenting the evolution of river morphology is becoming increasingly …

Agenda: A Low-Carbon Energy Blueprint For The American West, University Of Colorado Boulder. Natural Resources Law Center, University Of Colorado Boulder. Renewable And Sustainable Energy Institute, Western Resource Advocates, Rocky Mountain Research Station (Fort Collins, Colo.)

A Low-Carbon Energy Blueprint for the American West (Martz Summer Conference, June 6-8)

The future of the planet may depend upon our ability to increase energy supplies even as we reduce carbon emissions. This conference will address how a low-carbon energy program might evolve with a particular focus on the American West. It will focus on the future of energy in the West--on a “managed transition” to a different energy mix, on the need to nest this effort in a framework that acknowledges interconnections, and on identifying the most salient opportunities to consider the legal, political, financial, and technical challenges.

The Effects Of Biochar Age And Concentration On Soil Retention Of Phosphorus And Infiltration Rate, Emilie Schneider

Natural Resources Management and Environmental Sciences

Changes in land use and land management practices are regarded as one of the main factors in altering the hydrogeological system, causing changes in runoff, surface supply yields, and the quality of receiving water (Tong and Chen, 2002). Phosphorus is a significant contributor to accelerated eutrophication of fresh water and is largely sourced from agricultural runoff (Sharpley et al., 1994). The dominant processes controlling solution composition in agricultural soils are primarily ‘chemical’ for P (i.e. adsorption/desorption and dissolution/precipitation) (Edwards and Withers, 1998). Biochar has chemical characteristics that have the potential to adsorb P or influence precipitation of P insoluble pools …

Green Infrastructure Resource Directory, New England Environmental Finance Center

Sustainable Communities Capacity Building

Green infrastructure is an approach for managing stormwater that uses vegetation and soils to capture and treat rainwater where it falls. Unlike single-purpose gray infrastructure, green infrastructure realizes multiple benefits at once, including flood mitigation, improved water and air quality, community beautification, provision of recreational opportunities, and energy and cost savings. This resource directory is intended to help communities design, implement, fund, and monitor green infrastructure practices and programs. It was compiled by the Environmental Finance Center Network through the Capacity Building for Sustainable Communities program funded by U.S. Department of Housing and Urban Development and U.S. Environmental Protection Agency. …

A Survey Of Seafood Traceability And Sustainability In The United States— Processes, Regulations, And Current Initiatives, Nancy A. Olsen

Working Papers

The global seafood industry currently lacks a standardized, widespread method to easily trace the chain of custody of products that they purchase. With global overfishing leading to declining fish stocks around the world, it is vital for seafood providers to have the ability to identify and buy products from sustainable fisheries that are well managed, target abundant species, and fish in environmentally responsible ways. This paper analyzes public and private initiatives that seek to provide product traceability. In summarizing the current status of seafood traceability, stakeholders agree that are a number of challenges with trying to piece together so many …

Observations Of Localised Effects Of The Busselton Compensating Basins On Surface Water, Groundwater And Soil Salinity, D L. Bennett, Richard J. George Dr

Resource management technical reports

Between 2001 and 2009 the Water Corporation constructed three flood-compensating basins on farmland in the Vasse and Sabina river catchments, upstream of in the city of Busselton. The basins are designed to reduce the risk of flooding in urban areas of Busselton by temporarily storing and then regulating runoff during flood events. This report fulfils the reporting requirements of a contract between the Water Corporation and the Department of Agriculture and Food. Data relating to the local groundwater and surface-water dynamics, salinity, nutrients and pH, plus changes to shallow and deep-soil salinity (from repeat ground-based electromagnetic induction [EM] surveying), was …

The Effects Of Utility Pole Placement And Characteristics On Pentachlorophenol Concentrations Entering Underground Injection Control (Uic) Devices: City Of Gresham, Oregon, Katie Bohnren

Environmental Science and Management Professional Master's Project Reports

Urbanization is causing increased amounts of stormwater runoff, while simultaneously decreasing the amount of pervious surface area for infiltration. Multiple priority pollutants have been identified in urban stormwater, including pentachlorophenol (PCP). PCP is often found in stormwater samples exceeding the Safe Drinking Water Act limit of 1μg/L and can cause human health issues with exposure over time. Treated wood utility poles are the major source of PCP in urban stormwater. With the use of underground injection control (UIC) devices as an alternative method to treat and dispose of stormwater, the potential exists for groundwater contamination of PCP. The City of …

A Model To Relate Environmental Variation To Npdes Permit Violations At Thermoelectric Facilities On The Taunton River, Seth Delevan Sheldon

Graduate Doctoral Dissertations

Large thermoelectric facilities are issued permits to discharge high volume, high temperature effluents as part of the National Pollutant Discharge Elimination System (NPDES). Once-through cooled power plants are especially dependent on large quantities of cool water to operate. When ambient temperatures are high or streamflow is very low, power plant managers must reduce (i.e., "dial back") energy generation in order to avoid violating their NPDES permit limitations. Sudden dial-back can have human health impacts when electricity is no longer available to provide cooling or other vital services. A superior system of electricity and environmental management would reduce the probability of …

A Report On The Gascoyne River Catchment Following The 2010/11 Flood Events, Peter-Jon A. Waddell, P W.E Thomas, Paul A. Findlater

Resource management technical reports

In December 2010 an extreme tropical storm resulted in widespread flooding at Carnarvon and across the catchment. Another two flood events followed during the summer of 2010–11

The rationale for this assessment is to provide illustrative evidence on the role that perennial vegetation groundcover management has in influencing the risk of flooding and soil loss in the catchment. It may be possible that the impact of flooding associated with extreme storm events can be reduced. This report focuses on catchment condition and is not a review of the pastoral industry’s economic viability.
