Comparison Of Common Dredging Equipment Air Emissions , Mark J. Anderson P.E.

Dissertations, Master's Theses and Master's Reports - Open

The purpose of this study is to provide a procedure to include emissions to the atmosphere resulting from the combustion of diesel fuel during dredging operations into the decision-making process of dredging equipment selection. The proposed procedure is demonstrated for typical dredging methods and data from the Illinois Waterway as performed by the U.S. Army Corps of Engineers, Rock Island District. The equipment included in this study is a 16-inch cutterhead pipeline dredge and a mechanical bucket dredge used during the 2005 dredging season on the Illinois Waterway.

Considerable effort has been put forth to identify and reduce environmental impacts …

Performance Evaluation Of Vip Latrines In The Upper West Region Of Ghana , James W. Dumpert

Dissertations, Master's Theses and Master's Reports - Open

The prevalence of Ventilated Improved Pit (VIP) latrines in Ghana suggests that the design must have a high user acceptance. The two key factors attributed to user acceptance of a VIP latrine over an alternative latrine design, such as the basic pit latrine, are its ability to remove foul odors and maintain low fly populations; both of which are a direct result of an adequate ventilation flow rate.

Adequate ventilation for odorless conditions in a VIP latrine has been defined by the United Nations Development Program (UNDP) and the World Bank, as an air flow rate equivalent to 6 air …

The Effect Of Demand, Tank Parameters, And Pumping Stations On Energy Use In Municipal Drinking Water Distribution Systems, Santosh Raj Ghimire

Dissertations, Master's Theses and Master's Reports - Open

Two of the indicators of the UN Millennium Development Goals ensuring environmental sustainability are energy use and per capita carbon dioxide emissions. The increasing urbanization and increasing world population may require increased energy use in order to transport enough safe drinking water to communities. In addition, the increase in water use would result in increased energy consumption, thereby resulting in increased green-house gas emissions that promote global climate change. The study of multiple Municipal Drinking Water Distribution Systems (MDWDSs) that relates various MDWDS aspects--system components and properties--to energy use is strongly desirable. The understanding of the relationship between system aspects …

Planning And Adaptation Measures For Urban Slum Communities In West Africa : Stochastic Rainfall Modeling Applied To Domestic Rainwater Harvesting And Climate Change Adaptation, Joshua R. Cowden

Dissertations, Master's Theses and Master's Reports - Open

Over half of the world’s population is living in urban settlements, and most urban growth is occurring in developing countries. These countries’ economies are often unable to accommodate these rural-urban immigrations, resulting in millions of people settling in insecure communities known as urban slums. Current efforts to prevent urban slums include UN-HABITAT strategies to upgrade slums and stimulate urban/regional development. Urban metabolism analysis, which studies material and energy flows/stocks through urban processes, help decision-makers better understand their urban system. Nine lessons from past urban metabolism studies are presented to assist in finding answers on how to best solve urban slum …
