Number of years of transient operation <br />2. Number of years of simulation operation <br />3. Initial value to the random number generator <br />(uniquely determines sequence of flows generated). <br /> <br />System Control Variables: <br /> <br />Upper <br />1. <br /> <br />Basin Depletion Level, DPL <br />Monthly exports of water from each tributary basin, <br />(MAF /mo) <br />Monthly municipal and industrial consumption in each <br />tributary basin, (MAF/mo) <br />Monthly irrigation consumptive use in each tributary <br />basin (MAF/mo) <br />Monthly irrigation return flow of dissolved solids <br />in each tributary basin, (MT/mo) <br />Monthly side inflows of water and dissolved solids above <br />Lake Powell (MAF/mo), (MT/mo) <br />Monthly withdrawal from Lake Powell, (MAF/mo). <br /> <br />Basin Depletion Level <br />Monthly side inflows of water and dissolved solids between <br />Lakes Powell and Mead (MAF/mo), (MT/mo) <br />Monthly withdrawal from Lake Mead, (MAF/mo). <br /> <br />2. <br /> <br />3. <br /> <br />4. <br /> <br />5. <br /> <br />6. <br /> <br />Lower <br />1. <br /> <br />2. <br /> <br />(These control variables represent the only quantities within the <br />boundaries of the river system model which are affected by Lower <br />Basin depletions. The remainder of the Lower Basin water demand <br />is imposed as the target discharge for Lake Mead). <br /> <br />Reservoir Operating Parameters <br />1. Minimum allowable storage of Lake Mead, (MAF) <br />2. Maximum allowable storage of Lake Mead, (MAF) <br />3. Minimum allowable storage of Lake Powell, (MAF) <br />4. Maximum allowable storage of Lake Powell, SPm (MAF) <br />5. Target discharge for each reservoir, Dt, (MAF/yr) <br />6. The initial storage in each reservoir <br />7. The initial dissolved solids concentration in each <br />reservoir. <br />
