<br />outflow (and inflow) continuing for one interval. This step is repeated <br />for each interval of the flood. <br />~. The outflow hydrograph obtained in this manner should be routed <br />to downstream damage locations and combined with local runoff to evaluate <br />effects of design-flood regulation. Generally the outflow determination <br />for downstream conditions requires an iterative process bf trial re- <br />leases and routing to determine the maximum release that can be made <br />without causing flooding. Examples of a hand computation and computer <br />solution for an operation study for a single reservoir operating for <br />two downstream control points is shown in Exhibit 2 of the HEC-5C Users <br />Manual (Appendix 1). <br /> <br /> Table 3.01.
