Show (a) Hydrology - A historical study centering on the use of the Colorado River since the turn of the century and the development of major river projects during that period, including recorded changes in hydrologi-cal conditions and agricultural practices. (b) Biology - A pilot biological investigation aimed at determining indexes of water quality for analyses of eutrophication and shoreline terrestrial vege-tational changes that are occurring with reservoir filling, fluctuating water (in Lake Powell) , and changing water table. (c) Dynamic Limnology - An investigation of the physical processes taking place in Lake Powell, including thermal and chemical structure and sedimentation rates and distributions. (d) Environmental Impact - An analysis of the impact upon the regional environmental quality from technological enterprises (tourism, mining, and electrical power production) attendant with the impoundment of Colorado River water. At the end of the disciplinary phase, sufficient data had been gathered to define three separate subprojects each in categories (a), (b), and (c), and two sub-projects each in (d). Thus, 11 subprojects for natural science were generated and included in the proposal for the trial integration phases. For the natural sciences this represented a subdivision of disciplines into specialties and, in some ways, a move away from integration. The Trial Integration Phase The natural scientists together with the social scientists of the LPRP defined the societal problem for the focus of the Project's research as how to develop water resources and deal with the effects and ramifications of this development in the arid Southwest. This problem was addressed by formulation of the following goals: o To study the problems inherent in water resource management with regard to water allocation, water quality, power production, recreation, and aesthetic values of the environment. o To evaluate the expected consequences of alternative water management decisions upon the Lake Powell region. o To study the decision-making process in the development of water resources, and to disseminate information pertinent to future decisions. o To create a quantitative systems analysis model which is designed for use in the first three goals. The following 11 subprojects were organized to acquire and analyze the basic data in order to help meet the above goals: (a) Biological Limnology - To develop indices of eutrophication and measures of primary productivity, 12 |
