Desalination: Adapting To A Changing Climate And An Increasing Demand For Freshwater, Rebecca A. Acosta
Desalination: Adapting To A Changing Climate And An Increasing Demand For Freshwater, Rebecca A. Acosta
Master's Projects and Capstones
The state of California is just one place in the world that is experiencing an increasing demand for freshwater while also experiencing increasingly hotter conditions and longer periods of drought. There are a number of plants slated for development in the state of California but have been met with resistance from the public with concerns regarding their impacts to the surrounding marine environments. This paper provides background on desalination plants, provides evidence for a potential indicator species, identifies potential impacts to marine environments, and addresses stakeholder concerns and perceptions around desalination plants.
Stormwater To Groundwater: How California Can Increase Groundwater Storage And Build Climate Resilience., Emily M. Perales
Stormwater To Groundwater: How California Can Increase Groundwater Storage And Build Climate Resilience., Emily M. Perales
Master's Projects and Capstones
California is predicted to have more intense and frequent changes in weather patterns within the next 50 years. Historical and current groundwater use for residential and agricultural use is unsustainable and is creating significant deficits in groundwater aquifers throughout the state. To better adapt to potential damages caused by atmospheric rivers, better stormwater management and capture could increase California’s Climate adaptability. This study is focused on the means and methods to capture stormwater and increase groundwater recharge. Nature-based infrastructure (NBI), or Green Infrastructure (GI), has been used in urban areas throughout the country to mitigate harmful stormwater effects by replicating …
Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies
Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies
Master's Projects and Capstones
Riparian corridor protection through zoning ordinances is a common best management practice to protect riparian ecosystems and function. These zoning ordinances protect riparian ecosystems by establishing setback distances where land use activities are prohibited. While management of protected riparian corridors are widely studied, recommendations for riparian corridor width vary and are often site specific. The variability of corridor widths presents a challenge to riparian corridor implementation, in addition to balancing economic needs with natural resource protection. This study evaluates the effects of land use on riparian corridors and compares the Riparian Corridor Combining Zone ordinance in Sonoma County to other …
A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle
Master's Projects and Capstones
Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an extent …
Evaluation Of The Feasibility Of Struvite Precipitation From Domestic Wastewater As An Alternative Phosphorus Fertilizer Resource, Amanda R. Bird
Evaluation Of The Feasibility Of Struvite Precipitation From Domestic Wastewater As An Alternative Phosphorus Fertilizer Resource, Amanda R. Bird
Master's Projects and Capstones
Finite phosphate rock ore reserves are estimated to be exhausted in 100 to 150 years. Phosphate rock ore is the single global source material for phosphorus fertilizer production. Once these reserves are gone, agricultural production will be negatively impacted. There are currently no alternative phosphorus resources. However, phosphorus concentrations present in human excrement traveling through domestic wastewater treatment facilities is being disposed of directly to the environment, often resulting in pollution problems. Recovering phosphorus from wastewater with struvite precipitation systems at wastewater treatment plants can alleviate future phosphorus scarcities. Evaluation of phosphorus recovery through struvite precipitation at wastewater treatment plants …
Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera
Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera
Master's Projects and Capstones
Ecodistricts, or neighborhood-scale, community-driven areas of sustainable development, have emerged internationally and within the U.S. to create models of adaptive environmental design and advanced urban infrastructure. Central SoMa is the first ecodistrict to be planned and implemented in San Francisco, with the intention of revitalizing and greening this urbanized region of the city. At this time, the Central SoMa area has very low biodiversity levels, inefficient infrastructure, and poor water management capabilities. Through the implementation of ecodistricts in San Francisco, the city can integrate physical and behavioral sustainability measures from existing ecodistricts such as permeable surfaces, green roofs, stormwater management, …
Watershed Protection As The Primary Tool To Achieve High Quality Drinking Water, Kate J. Gazzo
Watershed Protection As The Primary Tool To Achieve High Quality Drinking Water, Kate J. Gazzo
Master's Projects and Capstones
In this study, a cost-effectiveness analysis and multiple case studies of cities ranging from New York City, USA to Bogota, Columbia are discussed to show how watershed protection can reduce the associated costs and risks stemming from impaired water and usually eliminate the need for human engineered treatment. A cost-effectiveness analysis was performed by comparing three municipalities that have obtained Filtration Avoidance Determinations through watershed protection (green infrastructure) compared with three municipalities that have installed human engineered filtration (gray infrastructure). Using turbidity and E. coli as indicators of effectiveness, the results of this analysis determined that human engineered infrastructure is …
