Patterns Of Dissolved Methane In Groundwater And Its Contribution To Emissions Inventories, Amanda E. Campbell
Patterns Of Dissolved Methane In Groundwater And Its Contribution To Emissions Inventories, Amanda E. Campbell
Dissertations - ALL
The Marcellus Shale is the largest shale gas play in the U.S. production of natural gas using high-volume hydraulic fracturing (HVHF) and production is prevalent throughout the play except in New York (NY), where it is currently banned. High concentrations of methane, the main component of natural gas, in groundwater, as well as its presence in the atmosphere, can have negative consequences. In this dissertation, three aspects of this issue are explored: 1) how and why naturally-occurring methane concentrations vary through time; 2) how elevated naturally-occurring methane concentrations in domestic water wells can be predicted from commonly observed well characteristics; …

As climate change occurs, the availability and stability of water resources will be a global concern. The availability of reliable water resources will be of particular concern to regions that currently depend on meltwater from snowpack or glaciers during dry periods. One place whose water stability could be heavily impacted by the loss of meltwater resources is Peru. During the dry, arid months of May through September, the region to the west of the Peruvian Andes relies on stream water resources that originate in proglacial alpine catchments. The Cordillera Blanca, which is a mountain range in the Peruvian Andes, contains …
Surface Water And Groundwater In A Changing Climate: Applications Of Hydrogeophysics And Trend Analysis To Understand Hydrologic Systems, Robin Glas
Dissertations - ALL
Water resources are being impacted by anthropogenic climate change worldwide, the nature and severity of that impact is determined by geographic position, local topography, underlying geology, and human influences such as land use, water availability, and water regulation. As global temperatures continue to rise due to greenhouse gas emissions, it is imperative that we better understand how water availability fluctuates with changes in air temperature, rainfall, snowpack, and glacial ice. This dissertation provides an analysis of the hydrologic response to both short-term and long-term climatic changes in both humid-temperate and semi-arid tropical regions. Within the tropical alpine zone, shifts in …
Quantifying Groundwater-Surface Water Interactions To Improve The Outcomes Of Human Activities, Ryan Parish Gordon
Quantifying Groundwater-Surface Water Interactions To Improve The Outcomes Of Human Activities, Ryan Parish Gordon
Dissertations - ALL
Interactions between surface water and groundwater impact both the quality and quantity of water resources. This dissertation is focused on the interactions between surface water in streams and groundwater in hyporheic zones and shallow fluvial aquifers, and how human beings influence these interactions and are influenced by them. The three chapters of this dissertation span scales from cm to km and locations from Upstate New York to the Peruvian Andes, but are united by the goal to improve the scientific understanding of groundwater-surface water interactions (GWSWI) using novel techniques, in order to improve the outcomes of human activities for people …
