Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

Creator:: Hosseini, Parnian
Abstract:: Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...

Watershed modeling at Yucca Mountain, Nevada

Creator:: Britch, Michael J.
Abstract:: Studies are currently underway to determine the suitability of Yucca Mountain in Nevada as the nation's first high-level nuclear waste repository. Values of net infiltration are required to determine pre-waste emplacement groundwater travel times and the performance of the repository as a waste containment system. The objective of this study...

U(VI) transport in subsurface materials: is two-site, one-species modeling sufficient?

Creator:: Harrington, Stephanie J.
Abstract:: Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorptive trend of U(VI) on Hanford sediment, and the changes in adsorption as both pH and total inorganic carbon...

A study of the quantity and distribution of bark debris resulting from log rafting

Creator:: Williamson, Kenneth J.
Abstract:: A study was conducted to determine the quantity and distribution of bark debris resulting from log rafting. Three distinct problems were studied: (I) the quantity of bark dislodged from the logs while being placed in the rivers and during transport in log rafts; (2) the percentage of the bark that...

3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

Creator:: Scoggins, Luke A.
Abstract:: A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Environmental Regulations Reconsidered : Identifying Incentives and Barriers to Environmental Performance

Creator:: Craig, Kathleen D.
Abstract:: Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...

Anaerobic reductive dechlorination of TCE and TCFE in TCE contaminated sediments : enhanced bioremediation and bioaugmentation

Creator:: Lee, Jae-Hyuk
Abstract:: This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

Depositional and diagenetic model for the Middle Devonian Denay Limestone, northern Antelope Range, Eureka County, Nevada

Creator:: Hoffmann, Heidi
Abstract:: Deposition of the Middle Devonian part of the Denay Limestone and Bay State Dolomite in the northern Antelope Range and Fish Creek Range, respectively, took place on and in front of a carbonate platform with a lime sand shoal at the shelf edge. In the Givetian part of the Denay...

A stochastic precipitation event model for use in erosion simulations

Creator:: Istok, J. D.
Abstract:: Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...
