Landfilling prevails in waste management options in Romania like others new EU members, being contrary to the concept of waste hierarchy promoted in recent years by EC. Waste disposal is done usually in non-compliant landfills and Government established a program to close these sites. This paper aims to analyse the transition from traditional waste management systems to an integrated system at national, regional and local scale. Assessment of landfills location based on buffer analysis (using GIS techniques) is made according to the proximity of five critical factors (CF) such as: residential area, industry & commercial units, agricultural lands, rivers & …


Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles Dec 2013

Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles

Masters Theses & Specialist Projects

Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …

Shoreline Evolution: Northampton County, Virginia Chesapeake Bay Shoreline 2013, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr.

Reports

Northampton County is situated along Virginia’s Eastern Shore (Figure 1). Because the County’s shoreline is continually changing, determining where the shoreline was in the past, how far and how fast it is moving, and what factors drive shoreline change will help define the shoreline’s future movement. These rates and patterns of shore change along Chesapeake Bay’s estuarine shores will differ through time as winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments. The purpose of this report is to document how the Chesapeake Bay shoreline of Northampton County has evolved since 1938. Aerial imagery …

Westmoreland County Shoreline Management Plan, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Mary C. Cox, Marcia Berman, Tamia Rudnicky, Karinna Nunez, Sharon Killeen

Reports

With approximately 85 percent of the Chesapeake Bay shoreline privately owned, a critical need exists to increase awareness of erosion potential and the choices available for shore stabilization that maintains ecosystem services at the land-water interface. The National Academy of Science recently published a report that spotlights the necessity of developing a shoreline management framework (NRC, 2007). It suggests that improving awareness of the choices available for erosion control, considering cumulative consequences of erosion mitigation approaches, and improving shoreline management planning are key elements to minimizing adverse environmental impacts associated with mitigating shore erosion.

Beijing’S Water Crisis: A Historical Analysis Of Beijing’S Waterways Using Geographic Information Systems, Rebecca Tisherman

Environmental Studies Honors Papers

Beijing has a complex system of waterways inside the city of 20 million people, while the rivers just outside of the city run dry most of the year. Geographic Information Systems was used to analyze the historical changes of the waterways, geo-cover, precipitation, and other factors that have affected the water supply to the city. The manmade canals in the city expanded with urbanization until 1983 when there were canals in every corner of the city. The water became too polluted for human use, so canals were slowly converted to culverts. Groundwater was depleted over time as well, so the …


Optimized Correlation Of Geophysical And Geotechnical Methods In Sinkhole Investigations: Emphasizing On Spatial Variations In West-Central Florida, Henok Gidey Kiflu Jan 2013

Optimized Correlation Of Geophysical And Geotechnical Methods In Sinkhole Investigations: Emphasizing On Spatial Variations In West-Central Florida, Henok Gidey Kiflu

USF Tampa Graduate Theses and Dissertations

Abstract

Sinkholes and sinkhole-related features in West-Central Florida (WCF) are commonly identified using geotechnical investigations such as standard penetration test (SPT) borings and geophysical methods such as ground penetrating radar (GPR) and electrical resistivity tomography (ERT). Geophysical investigation results can be used to locate drilling and field testing sites while geotechnical investigation can be used to ground truth geophysical results. Both methods can yield complementary information. Geotechnical investigations give important information about the type of soil, groundwater level and presence of low-density soils or voids at the test location, while geophysical investigations like GPR surveys have better spatial coverage and …

Winter Habitat Use By Juvenile Greater Sage-Grouse On Parker Mountain, Utah: Implications For Sagebrush Management, Danny Caudill, Terry A. Messmer, Brent Bibles, Michael R. Guttery

Human–Wildlife Interactions

Greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) are entirely dependent on sagebrush (Artemisia spp.) for food and cover during winter. Loss or fragmentation of important wintering areas could have a disproportionate affect on population size. We radio-marked and monitored 91 juvenile sage-grouse in south-central Utah from 2008 to 2010. Thirty-four individuals survived to winter (January to March) and were used to evaluate winter habitat use. Resource use was calculated using kernel density estimation of radio-marked individuals and compared to available habitat using a G-test. We found that juvenile sage-grouse used winter habitats characterized by 0 to 5% slopes …

Using Gis To Delineate Headwater Stream Origins In The Appalachian Coal-Belt Region Of Kentucky, Jonathan A. Villines Jan 2013

Using Gis To Delineate Headwater Stream Origins In The Appalachian Coal-Belt Region Of Kentucky, Jonathan A. Villines

Theses and Dissertations--Biosystems and Agricultural Engineering

Human activity such as surface mining can have substantial impacts on the natural environment. Performing a Cumulative Hydrologic Impact Assessment (CHIA) of such impacts on surface water systems requires knowing the location and extent of these impacted streams. The Jurisdictional Determination (JD) of a stream’s protected status under the Clean Water Act (CWA) involves locating and classifying streams according to their flow regime: ephemeral, intermittent, or perennial. Due to their often remote locations and small size, taking a field inventory of headwater streams for surface mining permit applications or permit reviews is challenging. A means of estimating headwater stream location …
