Mechanics And Physical Attributes Of Nature-Based Alterations: Rock Reinforcement And Urban Heat Island Assessment, Mary Chikondi Ngoma
Mechanics And Physical Attributes Of Nature-Based Alterations: Rock Reinforcement And Urban Heat Island Assessment, Mary Chikondi Ngoma
Dissertations
Ground improvement is critical to geotechnical and geo-engineering systems, where modification of the properties of geomaterials (rocks and soils) is required to maintain stability and prevent failure of infrastructure installed within and around them. This need has become increasingly important with rapid urbanization and population growth, which intensify demands on surface and subsurface systems and further challenge the performance of supporting geomaterials. As a result, there is growing interest in nature-based solutions, particularly biologically mediated processes such as biocementation, which can enhance the physical, hydraulic, and mechanical properties of geomaterials while offering environmentally sustainable alternatives to conventional ground improvement techniques. …
Using Geoscience To Empower A Community And Provide Access To Potable Groundwater, Hendratta Ali Dr
Using Geoscience To Empower A Community And Provide Access To Potable Groundwater, Hendratta Ali Dr
SACAD: Scholarly Activities
Access to potable water remains challenging around the world and remains one of the UN Sustainable Development Goals for 2030. Barriers to clean water access are exacerbated by the lack of technical expertise, limited funding for education and training, and the absence of reliable infrastructure that provides access to clean water. The Geoscientists Without Borders program, supported FHSU with funding to test, explore and provide access to clean potable groundwater to a rural community in Cameroon. We conducted water quality analyses, identified, mapped and located deep aquifers in fractured metamorphic rocks. Water quality analyses showed acidic pH and elevated amounts …
Evaluation Of Hydrophobic Materials For Stabilizing Expansive Soils, Suman Shrestha
Evaluation Of Hydrophobic Materials For Stabilizing Expansive Soils, Suman Shrestha
Civil Engineering Theses - Archive
The swelling and shrinkage of the expansive soil as a response to moisture change is one of the significant challenges posed to infrastructure projects. The significant economic damage that is caused by the expansive soil, as well as its abundance in nature, has prompted various scientists and engineers all around the world to actively search for new and improved methods for stabilizing it. Various traditional methods, such as lime and cement treatment, have been used extensively to stabilize expansive soils and mitigate their harmful effects on the infrastructure. Although these methods are quite often effective and various studies have been …
Estimating Aquifer System Storage Loss With Water Levels, Pumping And Insar Data In The Parowan Valley, Utah, Ryan G. Smith, Jiawei Li, Katherine R. Grote, Jim Butler
Estimating Aquifer System Storage Loss With Water Levels, Pumping And Insar Data In The Parowan Valley, Utah, Ryan G. Smith, Jiawei Li, Katherine R. Grote, Jim Butler
Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works
In the Parowan Valley of Utah, Groundwater Levels Have Declined by as Much as 30 M over the Past 50 Years with Accompanying Subsidence Rates of Up to 5 Cm/year. Traditional Methods to Estimate Groundwater Storage Change Use a Combination of Groundwater Level and Storativity Estimates, But There is Often Considerable Uncertainty in These. in This Study, We Demonstrate a New Method that Relies on a Combination of Geodetic Data from InSAR, as Well as Groundwater Level and Pumping Data, to Estimate Both the Total Groundwater Storage Loss and the Percentages of Storage Loss in Fine- and Coarse-Grained Layers within …

On October 29, 2012, Superstorm Sandy impacted 443,000 people and caused nearly $19 billion (about $58 per person in the US) worth of damage within New York City. As part of the New York City infrastructure reparation plan, the Living Breakwaters project in Tottenville addressed coastal resilience, allocating $100M of public funds to a series of artificial breakwaters by the southwest coast of Staten Island. Each breakwater is constructed and designed to mitigate water flow in storm events. ECOncrete, a primary element of the breakwater, is a specialty cast cementitious product that is marine organism-friendly that encourages biocalcification and photosynthesis. …

Publications and Research
On October 29, 2012, Superstorm Sandy caused nearly $19 billion in damages in New York City including 69,000 residential units across the five boroughs. This disaster precipitated a post-disaster-rebuilding (PDR) project including roughly $4.2 billion in a Community Development Block Grant allocated towards PDR projects. A portion of the grant was used to construct a living breakwater in Tottenville, Staten Island, consisting of a resiliency approach to risk reduction through erosion prevention, wave energy attenuation, and enhancement of ecosystems and social resiliency to improve resistance to storms for the community of Tottenville. The ridges of each breakwater are designed with …
