The Major Cause Of Observed Erosion Surge On The Beaches North Of Dar Es Salaam City, N. Nyandwi

Tanzania Journal of Science

Surges in coastal erosion north of Dar es Salaam city have been documented from 1977 to the early 1980s and around 1997/98. Analysis of the wind data shows that the documented increase in coastal erosion coincided with increased wind speeds. Extreme winds in excess of 10-11 m s-1 were experienced during 1976-78, 1984 and after 1996. Their coincidence with extreme high tides produced the high erosion rates. Using beach profile data for the years 1998-2000 the evolution of the beach profile with the changing monsoon winds and sediment input by rivers could be demonstrated. The beach erosion took place during …

Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella

Fire Science

Species selection can make the difference between successful revegetation projects and costly failures. Candidate native species for revegetating burned arid lands in the southwestern United States must meet at least two criteria. These species must: (1) be competitive in postfire environments typically dominated by exotic grasses, and (2) be able to become established reliably by seeding or planting. In response to Manager’s Request Task 3 (reestablishment of native vegetation after fires on arid lands) in the 2006 JFS announcement for proposals, this research tackled the problem of selecting native species with the greatest chance of revegetation success by conducting synergistic …

Due Diligence And Demographic Disparities: Effects Of The Planning Of U.S.- Mexico Border Fence On Marginalized Populations, J. Gaines Wilson, Jude A. Benavides, Karen Engle, Denise Gilman, Anthony Reisinger, Jessica Spangler, Joe Lemen

School of Earth, Environmental, & Marine Sciences Faculty Publications

In the buildup to the construction the U.S.-Mexico border fence by the United States Department of Homeland Security (USDHS), much attention was drawn to security, drug enforcement, and immigration issues. However, there was little quantitative analysis regarding which populations were most likely to be affected by the proposed fence. Using a geographic information system, we classified census blocks in Cameron County, Texas into one of two categories: either ‘fence’ or ‘gap’. A total of 14 demographic factors were tested for disparities between those living in gap areas and those living in areas exposed to the fence. Twelve of fourteen factors …

Quantifying Canal Leakage Rates Using A Mass-Balance Approach And Heat-Based Hydraulic Conductivity Estimates In Selected Irrigation Canals, Western Nebraska, 2007 Through 2009, Christopher M. Hobza, Michael J. Andersen

United States Geological Survey: Water Reports and Publications

The water supply in areas of the North Platte River Basin in the Nebraska Panhandle has been designated as fully appropriated or overappropriated by the Nebraska Department of Natural Resources (NDNR). Enacted legislation (Legislative Bill 962) requires the North Platte Natural Resources District (NPNRD) and the NDNR to develop an Integrated Management Plan (IMP) to balance groundwater and surface-water supply and demand in the NPNRD. A clear understanding of the groundwater and surface-water systems is critical for the development of a successful IMP. The primary source of groundwater recharge in parts of the NPNRD is from irrigation canal leakage. Because …

Environmental Consciousness: Human Motivation For Thinking Ecologically, Rob Pigue

Student Theses 2001-2013

What is the motivation for acting environmentally? Why do people care? What is the reason for buying fluorescent bulbs and hybrid cars, energy efficient appliances and reusable water bottles? Why is it that people turn off the lights when they leave a room, turn off the faucet while brushing their teeth, and go through the inconvenience of recycling?

Humans are known to act out of self-interest. Regardless of what people do or why they do it, their motivation can always be traced back to personal gain.

So why go green? Nothing about reducing, reusing, or recycling has any direct impact …

Nesting Ecology Of The Mississippi And Swallow-Tailed Kite In White River National Wildlife Refuge, Arkansas, Scott James Chiavacci

Student Theses and Dissertations

The Swallow-tailed (Elanoides forficatus; STKI) and Mississippi kite (Ictinia mississippiensis; MIKI) both express relatively poor reproductive success in White River National Wildlife Refuge (WRNWR), east-central Arkansas. I studied the nesting ecology of both species in WRNWR to determine factors contributing to their low nest survival. I located 41 MIKI nests from 2008-2009 and documented 8 causes of nest failure. The overall estimated probability of nest survival was ~25%, but estimated daily nest survival varied between nest periods among and across years. I found no consistent predictors of nest survival among the variables I measured. Also, I determined snake excluder devices, …

A Preliminary Assessment Of The Long-Term Prospects For Offshore Wind Farms In Maltese Territorial Waters, Dane Orion Zammit

Masters Theses, 2010-2019

Almost all of Malta’s current interest in offshore wind development is focused on the development of an offshore wind farm at Sikka L-Bajda in northwest Malta by 2020, to help the country reach its mandated 2020 RES target. The offshore wind industry is rapidly gaining momentum, with larger projects in deeper waters further offshore being commissioned every year. Countries like Germany and the United Kingdom have actively constructed, or are planning to construct, offshore wind farms at transitional water depths before 2020. The offshore wind energy market has historically been restricted to the North Sea, the Baltic Sea and the …

A Heuristic For Local Land Planning: Linking Ecological Function And Policy-In Context To Charlotte, North Carolina-, Kimberlee Robertella

Masters Theses, 2010-2019

Ecological systems and services are foundational to human well-being, and in recent years have received increasing scholastic attention. The functional ability of these systems is influenced however, by human-induced land transformation related to conventional patterns of growth and development. Such land transformations, which commonly occur as single-family residential development, are criticized as being wasteful and inefficient, leading to issues like air and water pollution, diminished forests and wetlands, and habitat loss and fragmentation. In the United States a patchwork of policy exists aimed at addressing such ecological concerns. Despite best efforts, most local governments and planning offices still miss the …

Integrated Waste Management In Malta-Future Scenario Development, Ruth Debrincat

Masters Theses, 2010-2019

Waste management is recognised as a major international environmental challenge since it is considered to be the loss of environmental resources. The Sixth Environment Action Programme (European Commission) calls for a cultural shift towards sustainable consumption patterns to bring about a reduction in waste generation. In Malta, the scale of waste generation, presently at 648 kg per capita (MEPA, 2008), and the need for sustainable waste management policies are of particular concern. The main objective of this dissertation was to adopt a systems view to evaluate the current status of integrated waste management in Malta and anticipate possible solutions in …

Exploring Sustainable Environmental Management Practices For Golf Courses In Semi-Arid Environments, Angelica V. Gurule

Masters Theses, 2010-2019

For the past several years NM government officials have been working to increase economic growth via tourism in NM. As a result several dozen golf courses have popped up around the state. Golf courses are conceived to be problematic as they consume large quantities of water and typically use lots of harmful pesticides to manage turfgrass. Water scarcity has already shown its face in NM: there are drought plans in place and growing evidence that illustrates the decrease in precipitation and an increase in temperatures, which will further reduce water resources. The scope of this paper is to analyze the …

Assessing Vulnerability To Coastal Hazards Case Study: Gozo, Jonathan Portelli

Masters Theses, 2010-2019

All coastal areas around the globe are vulnerable to a series of potential hazards at different degrees depending on location, altitude above sea level, geomorphological features and socio-economic factors, including demography, human settlement and infrastructural development. Since the 1990s a major effort in developing appropriate methodologies and guidelines to assess coastal vulnerability has been made. Of significant importance, the coast of Gozo embraces both natural and anthropogenic features that occupy a relatively small area. Consequently, coastal vulnerability by multiple coastal hazards is a fact due to the topography of the island, overpopulation in some coastal locations, and intensive coastal development …

2010 Fall Engr333 Project Final Report, 2010 Fall Engr333

ENGR 333

Calvin College dorms have a chronic issue with wasting energy. The dorms have little insulation, high infiltration rates, and are heated by low efficiency boilers. These existing characteristics combine for a larger required heating load and increased energy usage. The excess heat, due to poor temperature control, is often vented out through the windows whenever students deem necessary. This project will attempt to reduce wasted energy and efficiently distribute heat as needed.

The Thermal Systems Design class of 2010 was challenged with retrofitting the Bolt-Heyns-Timmer (BHT) dorm to decrease energy consumption and improve efficiency. The class was presented with the …

The Vinylguaiacol/Indole Or Vgi ("Veggie") Ratio: A Novel Molecular Parameter To Evaluate The Relative Contributions Of Terrestrial And Aquatic Organic Matter To Sediments., Michael A. Kruge, Kevin K. Olsen, Jaroslaw W. Slusarczyk, Elaine Gomez

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The organic matter (OM) fraction of estuarine sediments is often distinctive and thus diagnostically useful in determinations of sedimentary provenance. Among the most fundamental distinctions to be made is that between terrestrial and aquatic OM. To supplement the parameters commonly used for this purpose (e.g., C/N and stable isotope ratios), we proposed the Vinylguaiacol/Indole or VGI ("Veggie") ratio, defined as [vinylguaiacol / (indole + vinylguaiacol)] using data produced by analytical pyrolysis-gas chromatography/mass spectrometry of dried, homogenized sediment samples. The ratio employs the peak areas of these two compounds on the mass chromatograms of their molecular ions (m/z 150 and 117). …

Factors Influencing Macroinvertebrate Diversity And Community Composition In Riverine Freshwater Rock Pools, Chtaura Jackson

Theses and Dissertations

I examined a system of 378-riverine rock pools situated along the James River in Richmond, Virginia, to uncover the factors influencing their macroinvertebrate diversity and community composition. I characterized (total = 60) the physical characteristics, water quality, hydrology, and community assemblages in July 2009 for a subset of pools. I examined whether selected environmental factors (pH, nearest neighbor distance, depth, surface area and inundation height) were related to macroinvertebrate diversity and community composition. Species richness and total abundance of all taxa increased with pool pH and surface area. Ordination indicates that nearest neighbor distance (NND) and pH varied significantly among …
