Climate Change Adaptation for Southern California Groundwater Managers: A Case Study of the Six Basins Aquifer

Groundwater has been very important to the economic development of Southern California, and will continue to be a crucial resource in the 21st century. However, Climate Change threatens to disrupt many of the physical and economic processes that control the flow of water in and out of aquifers. One groundwater manager, the Six Basins Watermaster in eastern Los Angeles and western San Bernardino Counties, has developed a long-term planning document called the Strategic Plan that mostly fails to address the implications of Climate Change, especially for local water supplies. This thesis presents an in-depth analysis of the Six Basin Watermaster’s Strategic Plan as a case-study of how groundwater managers can improve their planning assumptions to better prepare for Climate Change. It begins with a brief history of how Southern California’s environment influenced the development of the institutions that manage the Six Basins’ groundwater, then provides a physical description of the aquifer itself. The current scientific literature on Climate Change’s expected impacts on California water supplies are summarized, and the implications of these impacts for basin management are highlighted. The Strategic Plan’s projects are evaluated and critiqued in light of these insights, including a need for the Strategic Plan to: explicitly consider Climate Change in its planning assumptions, use decision-making frameworks that account for uncertainty, and prepare for more frequent droughts and floods in the future. Climate Change will have important effects on how Southern California’s groundwater is managed, and the Six Basins Strategic Plan should be revised to better account for these impacts

Loss of life years after a hip fracture: Effects of age and sex

Background Patients with a hip fracture have a high mortality; however, it is not clear how large the loss of life-years is over an extended observation period

Surrogate Reactions in the Actinide Region

Over the past three years we have studied various surrogate reactions (d,p), ({sup 3}He,t), ({alpha},{alpha}{prime}) on several uranium isotopes {sup 234}U, {sup 235}U, {sup 236}U, and {sup 238}U. An overview of the STARS/LIBERACE surrogate research program as it pertains to the actinides is discussed. A summary of results to date will be presented along with a discussion of experimental difficulties encountered in surrogate experiments and future research directions

Launch Vehicle Sizing Benefits Utilizing Main Propulsion System Crossfeed and Project Status

To meet the goals for a next generation Reusable Launch Vehicle (RLV), a unique propulsion feed system concept was identified using crossfeed between the booster and orbiter stages that could reduce the Two-Stage-to-Orbit (TSTO) vehicle weight and Design, Development, Test and Evaluation (DDT&E) costs by approximately 25%, while increasing safety and reliability. The Main Propulsion System (MPS) crossfeed water demonstration test program addresses all activities required to reduce the risks for the MPS crossfeed system from a Technology Readiness Level (TRL) of 2 to 4 by the completion of testing and analysis by June 2003. During the initial period, that ended in March 2002, a subscale water flow test article was defined. Procurement of a subscale crossfeed check valve was initiated and the specifications for the various components were developed. The fluid transient and pressurization analytical models were developed separately and successfully integrated. The test matrix for the water flow test was developed to correlate the integrated model. A computational fluid dynamics (CFD) model of the crossfeed check valve was developed to assess flow disturbances and internal flow dynamics. Based on the results, the passive crossfeed system concept was very feasible and offered a safe system to be used in an RLV architecture. A water flow test article was designed to accommodate a wide range of flows simulating a number of different types of propellant systems. During the follow-on period, the crossfeed system model will be further refined, the test article will be completed, the water flow test will be performed, and finally the crossfeed system model will be correlated with the test data. This validated computer model will be used to predict the full-scale vehicle crossfeed system performance
