A Framework And Analytical Approach To Evaluate Alternative Vehicle Miles Traveled (Vmt) Fee Systems, Elizabeth V. Ebacher
A Framework And Analytical Approach To Evaluate Alternative Vehicle Miles Traveled (Vmt) Fee Systems, Elizabeth V. Ebacher
Doctoral Dissertations
Since the fuel tax is a dwindling source of revenue, states need to find alternative funding sources. A vehicle miles traveled (VMT) fee has received serious consideration from a number of states and the federal government. What is missing from the VMT fee consideration is a framework for developing VMT fee systems and an analytical approach with which to study how well a proposed system conforms to the policies promulgated in the framework. This research strives to fill that void. The framework developed presents five areas of importance in VMT fee systems: 1. Revenue sufficiency; 2. Revenue stability; 3. Environmental …
Essays On The Quantification And Propagation Of Uncertainty In Climate Change Impact Assessments For Water Resource Systems, Scott Steinschneider
Essays On The Quantification And Propagation Of Uncertainty In Climate Change Impact Assessments For Water Resource Systems, Scott Steinschneider
Doctoral Dissertations
Sustainable water resources planning and management under climate change requires a proper treatment of uncertainties that emerge in an impacts analysis. A primary source of this uncertainty originates from the difficulties in projecting how anthropogenic greenhouse gas emissions will evolve over time and influence the climate system at regional and local scales. However, other sources of uncertainty, such as errors in modeling hydrologic response to climate and the influences of internal climate variability, compound the effects of climate change uncertainty and further obscure our understanding of water resources performance under future climate conditions. This work presents an approach to quantify …
Impact Of Water Heating On Disinfection Byproducts Concentration, Boning Liu
Impact Of Water Heating On Disinfection Byproducts Concentration, Boning Liu
Doctoral Dissertations
Drinking water disinfection byproducts (DBP) are a group of inorganic and organic compounds formed during water disinfection. Epidemiologic studies suggest an association between rectal, and colon cancer and exposure to DBPs in chlorinated surface water. Therefore, DBPs are a growing public health concern; one that has been mitigated by multiple regulations of US Environmental Protection Agency (EPA) including the Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 DBPR). Tremendous efforts and cost have been spent on controlling DBPs in drinking water; however, human exposure has been poorly characterized. In addition to ingestion exposure, inhalation and dermal absorption during showering …
