Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Theses and Dissertations (Comprehensive)
The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Beaver Creek Restorative Design Using Engineering In Nature, Lindsay M. Levatino
Beaver Creek Restorative Design Using Engineering In Nature, Lindsay M. Levatino
Senior Honors Projects, 2020-current
Stream restoration work can be instrumental for the wellbeing of an ecosystem. Located in the Shenandoah Valley in Virginia is Beaver Creek, a well-known spot for fly-fishing due to its pristine water conditions and open surroundings. In order to maintain these conditions, a 100-foot stretch of Beaver Creek needed to be restored to prevent further erosion, stabilize the banks, and enhance the natural habitats. The project involved excavating a sediment island, filling in an eroded bank, building a cross vane, and adding stakes. Local stakeholders came together to complete this project contributing their expertise, equipment, and time. The construction was …
Irrigation Design In Montana: Accommodating Varying Water Accessibility Across The Continental Divide., John Garrett Lampson
Irrigation Design In Montana: Accommodating Varying Water Accessibility Across The Continental Divide., John Garrett Lampson
Biological and Agricultural Engineering Undergraduate Honors Theses
The design work performed in this project was conducted over two summers (2018, 2019) of internship experience with the Natural Resources Conservation Service (NRCS) across the state of Montana. The first summer’s design work was based out of Glendive, MT, in Dawson County, approximately 50 kilometers from the North Dakota border. The second summer was in Missoula, MT, in Missoula County, near the Idaho border. The two areas differ significantly in topography, weather, and water availability with the main separating geographic influence being the Rocky Mountains.
This paper focuses on the design process and requirements for two farms located outside …
Dry River Watershed Valuation And Management Plan, Julia Hutchens
Dry River Watershed Valuation And Management Plan, Julia Hutchens
Senior Honors Projects, 2010-2019
Water quality has become a major environmental and human welfare concern in the world today, it’s no longer just for developing countries. There have been many incidences in the US of health problems related to water quality and a shortage of water. The City of Harrisonburg and the surrounding community also have a need for a well-developed watershed management plan. The focus of this study will be the Dry River because that is a main source of the city’s water. The Dry River watershed is threatened by illegal dumping, erosion from primitive roads and future road building sedimentation, a lack …
The Future Of Construction As It Applies To The Colonization Of The Moon And Mars, Julian Prestia
The Future Of Construction As It Applies To The Colonization Of The Moon And Mars, Julian Prestia
UNLV Theses, Dissertations, Professional Papers, and Capstones
The goals of this research are:
1. To compile a comprehensive list of all the viable known solutions (and early stage potential solutions) to the issues related to constructing permanent, sustainable, and safe structures for human colonies on our moon and Mars,
2. Determine the most effective potential solutions, and
3. Further develop these ideas as to assist in further space endeavors.
This proposed paper will assist space experts in determining the best next steps in the development of deep-space travel and colonization technologies. Preliminary research has identified several key problems associated with establishing space colonies. They are as follows: …
Ncma Groundwater Model Using Usgs Modflow-2005/Pest, Brian Matthew Wallace
Ncma Groundwater Model Using Usgs Modflow-2005/Pest, Brian Matthew Wallace
Master's Theses
A numerical model for the NCMA aquifer complex is presented. The objective of the study is to develop a numerical groundwater model for the NCMA aquifer system to enhance the understanding of subsurface groundwater flow. Infiltration, streamflow, pumping, and return flows are implemented to characterize the aquifer complex over time. The numerical model is calibrated to municipal and monitoring well data, average monthly water balances, and hydraulic contours. Transient aquifer inflows and outflows are assessed in the results of the study and are compared to balance terms from previous studies. The 2007 Todd Engineers Study subsurface inflows and outflows generate …
Decision Making Of Environmental Engineers On Project Selection, Millicent Amanda Davis
Decision Making Of Environmental Engineers On Project Selection, Millicent Amanda Davis
Walden Dissertations and Doctoral Studies
Some environmental engineers do not understand how to perceive profitable opportunities in redeveloping the large number of contaminated brownfield sites in New Jersey. The purpose of this qualitative exploratory case study was to find effective decision-making strategies that help environmental engineers acquire profitable environmental redevelopment projects. The target population consisted of 4 environmental engineers in an environmental organization in Camden County, New Jersey who possessed proven decision-making strategies that helped them acquire profitable environmental redevelopment projects in the past 5 years. The conceptual framework for this study was the multiple criteria decision method (MCDM). Semistructured interviews were conducted with the …
A Study Of Central Florida Nonroad Voc And Nos Emissions And Potential Actions To Reduce Emissions, Michael Radford
A Study Of Central Florida Nonroad Voc And Nos Emissions And Potential Actions To Reduce Emissions, Michael Radford
Electronic Theses and Dissertations
Ground-level ozone is harmful to the human respiratory system, as well as the environment. The national EPA 8-hour ozone standard for ground-level ozone was reduced from 85 parts per billion (ppb) to 75 ppb in 2008, and trends from previous years show that some of the counties in Central Florida could be in danger of violation. Violation means "non attainment" status; in which the county is ordered by EPA to develop specific implementation plans to reduce its emissions. The objective of this study was to compile an emissions inventory of volatile organic compounds (VOCs) and nitrogen oxides (NOx) from nonroad …
Polarographic Determination Of Germanium, Calvin Leo Stevenson
Polarographic Determination Of Germanium, Calvin Leo Stevenson
Bachelors Theses and Reports, 1928 - 1970
In the past germanium has been determined by either wet methods or by the spectograph; the spectograph being used for the determination of very small amounts of germanium and wet methods used when more than one hundredth of one percent germanium is present. Both of these analytical schemes have weaknesses.
A Study Of The Effects Of The Chloride Ion On The Lead-Silver Anodes And On The Lead Tenor Of The Zinc Deposit In Zinc Electrolysis, William A. Mitchell
A Study Of The Effects Of The Chloride Ion On The Lead-Silver Anodes And On The Lead Tenor Of The Zinc Deposit In Zinc Electrolysis, William A. Mitchell
Bachelors Theses and Reports, 1928 - 1970
The electrolyte used in the commercial production of electrolytic zinc from zinc sulphate solutions contains small amounts of impurities each of which has its own effects upon the process. Impurities such as antimony, cobalt, nickel, and iron tend to lower the current efficiency while other impurities such as chlorine, fluorine, and nitrates tend to increase the corrosion of the lead anodes and thereby increase the lead tenor of the zinc deposit.
