On-Site Design Of A Water Filtration System In Rural Ghana, Donald Eugene Long
On-Site Design Of A Water Filtration System In Rural Ghana, Donald Eugene Long
Construction Management
Agbokpa is a rural community in southern Ghana with no access to clean or running water. Villages without access to water face significant hurdles in obtaining an education and developing their communities’ infrastructure and economy. In August of 2019 Cal Poly students Eugene Long, Fletcher Podosek, and Mason Nolan traveled with professors Paul Redden and Dr. Nathan Heston to Agbokpa to fix this problem. The team spent three weeks living in the village and constructing a water tower, pumping system, and filtration system that communally serves the village. The team worked with local craftsmen and sourced nearly all equipment and …

Journeyman International - Kilimbi Community Center And Eco-Lodge - Rwanda, Africa, Chris Audi
Construction Management
This project based senior project is an interdisciplinary partnership with a non-profit called Journeyman International (JI) and students from the College of Architecture and Environmental Design (CAED) at Cal Poly San Luis Obispo (Cal Poly). Journeyman International worked Empowering Villages and our design team to design a community center, eco-lodge, and guest houses to enable the local population to take advantage of a tourism heavy area creating jobs and income. Empowering Villages objective is to empower, train, and build up the people they work with and hope to someday see Villages around the world become self-sufficient by working with locals …
Technology For Integrated Groyne-Vetiver Erosion Reduction (Tiger): Case Study In A West African River, Chase M. West
Technology For Integrated Groyne-Vetiver Erosion Reduction (Tiger): Case Study In A West African River, Chase M. West
Dissertations, Master's Theses and Master's Reports
River erosion is a problem all over the world. The effects of river erosion are especially hard for farmers in developing countries, where the river is an important part of their farming practices and daily lives. A case study was done in the small village of Fode Binea in Senegal, West Africa to reduce this stream erosion. A new hybrid approach, Technology for Integrated Groyne-Vetiver Erosion Reduction (TIGER) method, was developed. The method includes combining groynes at the toe of the riverbank to reduce toe erosion in the channel and planting a buffer strip with vetiver grass to reduce erosion …
Techno- Economic Feasibility Study Of Solar Water Pumping For Public Facilities In Nigeria, Anamika Singh
Techno- Economic Feasibility Study Of Solar Water Pumping For Public Facilities In Nigeria, Anamika Singh
Cal Poly Humboldt theses and projects
This thesis presents a techno-economic feasibility analysis of solar water pumping systems in public facilities located in rural parts of Nigeria. Three different public facilities namely, a primary health care center in Ibwa (PHC, Ibwa), a comprehensive health care center in Kwali (CHC, Kwali), and the LEA Primary School in Mapa (LEA School, Mapa), all located in Federal Capital Territory (FCT) of Nigeria, were analyzed. The facilities considered in the study have varying levels of water demand (micro, small, and medium), and they are used as cases to establish the techno-economic suitability of solar water pumping systems to deliver water …
A Life Cycle Assessment Of A Uranium Mine In Namibia, Janine Lambert
A Life Cycle Assessment Of A Uranium Mine In Namibia, Janine Lambert
USF Tampa Graduate Theses and Dissertations
Uranium mining and nuclear power is a controversial topic as of late, especially in light of the recent Fukushima event. Although the actual use of nuclear fuel has minimal environmental impact, its issues come at the very beginning and end of the fuel’s life cycle in both the mining and fuel disposal process. This paper focuses on a life cycle analysis (LCA) of uranium mine in the desert nation of Namibia in Southern Africa. The goal of this LCA is to evaluate the environmental effects of uranium mining. The LCA focuses on water and energy embodiment such that they can …
Investigation Of The Behavior Of Free-Standing Gabions In Seismic Regions, Amy Ransom
Investigation Of The Behavior Of Free-Standing Gabions In Seismic Regions, Amy Ransom
Master's Theses
This thesis investigates the behavior of free-standing gabion walls in areas of mild seismicity. To investigate this behavior, three walls of varying internal cable patterns were constructed at a quarter-scale. These walls were tested with a mass shaker, and mode shapes, tone extractions, and damping ratios were calculated. A modal analysis was conducted using design spectra created from a suite of seven earthquakes from countries bordering Kenya. The corresponding lateral forces to these spectral displacements were found, and the restoring eccentricities from the soil restoring force were backed out through a summation of moments. All analysis was experimentally done due …
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 …
