<br />level is determined for the tandem reservoirs (one above the other) <br />based on the combined storage in the tandem reservoirs. <br />- If two reservoirs are in tandem, the upstream reservoir <br />can be operated for control points between the two reservoirs. In <br />addition, when the downstream reservoir is being operated for control <br />points, an attempt is made to bring the upper reservoir to the same <br />index level as the lower reservoir. <br />A variety of streamflow routing procedures, such as the Muskingum <br />and modified Puls methods, are available for use. The hydrologic input <br />for flood events may be for natural or observed conditions for each <br />control point or local contributions between control points. If <br />natural or observed flows are provided, the local flows are computed <br />and if local flows are provided. the natural flows are computed. <br /> <br /> <br />A single streamflow diversion can be made from any reservoir <br /> <br /> <br />or control point and. if desired, proportions of the diversion can <br /> <br /> <br />be routed and returned at any downstream control point or reservoir. <br /> <br /> <br />Diversions may be one of the following types: <br /> <br /> <br />- Diversions that are a function of inflows. <br /> <br /> <br />- Diversions that are functions of reservoir storages. <br /> <br /> <br />- Diversions that are constant. <br /> <br /> <br />- Diversions that include all excess water above the top <br /> <br /> <br />of conservation pool up to the diversion facility capacity, <br /> <br />11 <br />
