Hvdrolo2:ical Sensitivitv <br />a. Future hydrologic yields of the basin are uncertain. To provide additional <br />insight into the results produced from the base scenario in this study, the <br />95 year study period used in tIlis study will be characterized based on <br />minimum. maximum and mean flows events that may have been estimated <br />from previous analyses using tree rings or synthetic hydrology. <br />b. To address concerns that future hydrology may yield less water than <br />shown by the recent 95 year period (1909 - 2003). sensitivity analysis will <br />be performed on the depletions and resulting flows in the subbasins by <br />reducing the hydrological base used in Task 5 by a percentage (reducing <br />flow in each base flow sector).1 f9~ ~1~eJ~u_rp<?~e~ _o!~~i~ ~!l!.d)'.: !l~'~~ ~l~~-_ _ _...... <br />base flow data sets will be created with the following percentages of the <br />original flow data values: <br />i. 95 percent of the original values <br />ii. 90 percent of the original values <br />iii. 80 percent of the original values <br />c. Each of the modified flow databases prepared in the previous step will be <br />combined with other State Mod input data sets used in Task 6 to create <br />three reduced flow scenarios. Executions of the model will be performed <br />for each of these three scenarios. <br /> <br />Colorado River Water A \'ailability Study Scope <br /> <br />7 <br /> <br />June 25. 2007 Draft <br /> <br />Comment: I suggest adding a literature <br />revie\v of climate studies to determine or <br />verify the appropriate percentages.
