Flood Control Studies The magnitude of the flood problem indicates the need for a research program for flood damage reduction. Specific suggestions for more detailed studies include: 1. The problem of urban hydrology should be studied. Because of rapid urbanization, greater runoff occurs in these areas. 2. Since a large part of the Region is in an arid area, a study should be made of desert hydrology. 3. Research to determine the potential for storing floodwater in underground reservoirs created by nuclear devices and the fracturing of rocks to create greater infiltration rates of percolation. k. Research to develop better hydrologic models for flood fore- casting. 5. To improve flood warning system by research in precipitation forecast through radar sounding and other means. 6. Further studies to evaluate alternative means of obtaining flood protection in specific areas should include, but not be limited to, environmental considerations, nonstructural flood plain management measures, and open space. Electric Power Studies The projected large increases in the demand for electric power will require investigations to determine the most suitable locations for the thermal eiectric power plants. Environmental considerations and avail- ability of water for cooling will be of primary consideration. Thermal pollution is presently avoided through use of cooling towers. The use of dry-cooling towers should be evaluated in terms of the value of the water conserved compared to the additional cost that would be entailed. Specific reaches of rivers and flood plains having unusual scenic or ecological qualities, and other areas of historic or esthetic signi- ficance, need to be identified so that they can be avoided in planning for electric power plants and transmission facilities. 126
