  	Citation × Citation Citation Abstract Copy Title: Potential Growth of Electric Power Production from Imperial Valley Geothermal Resources Author: Ermak, D.L. Year: 1977 The growth of geothermal electric power operations in Imperial Valley, California is projected over the next 40 years. With commercial power forecast to become available in the 1980's, the scenario considers three subsequent growth rates: 40, 100, and 250 MW per year. These growth rates, along with estimates of the total resource size, result in a maximum level of electric power production ranging from 1000 to 8000 MW to be attained in the 2010 to 2020 time period. Power plant siting constraints are developed and used to make siting patterns for the 400- through 8000-MW level of power production. Two geothermal technologies are included in the scenario: flashed steam systems that produce cooling water from the geothermal steam condensate and emit noncondensable gases to the atmosphere; and high pressure, confined flow systems that inject the geothermal fluid back into the ground. An analysis of the scenario is made with regard to well drilling and power plant construction rates, land use, cooling water requirements, and hydrogen sulfide emissions Title: Potential Growth of Electric Power Production from Imperial Valley Geothermal Resources Author: Ermak, D.L.

  Citation × Citation Citation Abstract Copy Title: A statistical analysis of Oregon's land-use ballot initiative Author: Fuller, Justin This paper explores predictors of support for land-use ballot initiatives in Oregon. Possible predictors include a variety of socioeconomic, spatial, and political variables. Multiple least squares regressions find that aggregate levels of education within a county and the proportion of a county's workforce engaged in farming or forestry occupations appear to play a strong role in county-level land-use ballot initiative results. These effects of education and industry sector employment are consistent across multiple elections. Real per capita income and party identification appear to play a role in specific elections and are not consistent predictors. Analysis from initiatives in 1970, 1976, 1978, 1982, 2000, and 2004 from Oregon are used to draw these conclusions.

  Citation × Citation Citation Abstract Copy Title: The Influence of Measure 37 claims on the shift in vote between Measure 37 and Measure 49 Author: Chrostek, Garrett The passage of Measure 37 in 2004 was met with a great deal of controversy as a number of voters claimed the implications of the Measure did not represent their intentions for supporting the legislation. Namely, significant opposition was aimed towards the Measure 37 claim which offered landowners financial compensation or waivers from land use regulations that reduced the value of their property. As a result, voters subsequently passed Measure 49 which drastically curtailed the size and scope of the Measure 37 claim. Both measures experienced strong support and passed with more than 60% of the vote. This paper seeks to identify voting patterns by examining those factors which led to the divergent outcomes between the two elections. A review of the literature reveals two primary theories for explaining the differing outcomes. The first is premised on the concept of NIMBY (not in my backyard) in which voters in areas with high concentrations of Measure 37 claims used their vote to resist unfavorable developments associated with Measure 37 claims. A second theory is rooted in traditional regional and partisan differences, which characterize the “two states” view of Oregon politics. This paper evaluates these theories by developing testable hypothesis to predict the “shift in vote” at the county and precinct levels of analysis. Results from this study will offer a better understanding of voting behavior on this issue and offer suggestions to policymakers looking to improve voter satisfaction with Oregon’s land use system.

  Citation × Citation Citation Abstract Copy Title: The effects of land use on mineral flat wetland hydrologic processes in lowland agricultural catchments Author: Marshall, Sarah M. (Sarah Marie) Hydrologic processes within mineral flat wetlands, along with their connections to groundwater and downstream surface water in lowland agricultural catchments are poorly understood, particularly under different land uses. In the three field studies included in this thesis, we examined infiltration, wetland hydroperiod, groundwater recharge dynamics, surface runoff generation, and water quality in mineral flat wetlands using a combination of soil and hydrometric measurements, stable isotope tracers, and water chemistry analysis. Our overarching objectives were to examine, for mineral flat wetlands under native prairie, farmed grassland, and restored prairie land cover: 1) how different land management influences infiltration and wetland hydroperiod at the plot scale, 2) the effects of land use on seasonal groundwater-surface water dynamics at the field scale, and 3) seasonal variation in runoff sources and nutrient transport from native prairie and farmed wetlands at the small catchment scale. At the plot scale, our results suggest that edaphic factors, particularly those related to soil structure, are strongly associated with wetland infiltration and overall hydroperiod across least-altered prairie, farmed, and restored prairie mineral flat wetlands. The hydroperiod metrics we examined were generally more sensitive to level of site disturbance than land use alone. At the field scale, our results indicate that, in spite of land use differences and slight variations in soil stratigraphy, many similarities exist in overall wetland hydroperiod, water sources and evaporation rates for mineral flat wetlands in the Willamette Valley lowlands. Isotopic evidence suggests that the greatest degree of groundwater-surface water mixing occurs in the upper 0.5 m of the saturated soil profile across sites under all land uses. Finally, at the small catchment scale, farmed wetland runoff was isotopically similar to field surface water for most of the wet season, indicating that saturation excess was an important runoff generation process. Prairie wetland runoff was isotopically similar to upstream water throughout the winter, and briefly similar to shallow groundwater and surface water within the wetland in mid-spring. Throughout the wet season, elevated nitrate, sulfate, and chloride concentrations were observed in groundwater and surface water at the farm site, and deeper groundwater at the prairie site. Upstream-downstream runoff chemistry remained similar throughout the wet season at the prairie site. Farm site runoff chemistry reflected the dominant water source within the farm field throughout the wet season. Our findings suggest that, while surface water pathways dominate runoff from wetland flats under farm land use, large wetland flat fields have a high potential to absorb, store, and process nutrients and agrochemicals from on-site and nearby off-site chemical inputs. Mineral flats that maintain wetland hydrology in spite of farm use represent a unique balance between agricultural production and preservation of some of the water storage and delay, and water quality-related ecosystem services once provided at a much larger scale in the Willamette Valley lowlands. We anticipate that results of this work will lead to better understanding of key site-scale edaphic and hydrologic factors to consider when prioritizing and managing sites for restoration, and how site disturbance under a variety of land uses may impact different hydrologic processes and components of the wetland hydroperiod. Additionally, our results provide a better understanding of how land use affects seasonal runoff generation processes in mineral flat wetlands, and the water quality implications of modifying groundwater and surface water connectivity between mineral flats and surrounding surface drainage networks.
