<br />necessary data be assembled and coded into the proper format. <br /> <br /> <br />The major requirements for modeling a flood system include <br /> <br /> <br />(1) schematizing the basin by identifying operational control points, <br /> <br /> <br />daroage index locations, and potential reservoirs, (2) developing con- <br /> <br /> <br />sistent basin-wide (control point by control point) hydrology that <br /> <br /> <br />could include one, or preferrably more, historic events or synthetic <br /> <br /> <br />events, (3) developing streamflow routing criteria for all stream <br /> <br /> <br />reaches, (4) characterizing reservoirs by their storage and release <br /> <br /> <br />capacities, (5) determining operation criteria such as selecting <br /> <br /> <br />control points to operate for, determining their safe flow capacity, <br /> <br /> <br />and specifying release priorities, (6) developing functional damage <br /> <br /> <br />relations and base conditions exceedence frequency relations for <br /> <br />each damage index location. <br /> <br />Computer Program HEC-5C(1), "Simulation of Flood Control and <br />Conservation Systems," has been developed by The Hydrologic Engineer- <br />ing Center, U.S. Army Corps of Engineers, as a generalized tool which <br />can be used to simulate any flood control system. The program was <br />written to be compatible with generally accepted analysis procedures <br />that require data normally developed in the course of studying flood <br />control reservoirs. The general capabilities of HEC-5C are described <br />"below. The flood control features are particularly emphasized. <br /> <br />(1) HEC-5C, Simulation of Flood Control and Conservation Systems, <br />Users ~Ianual (Preliminary), The Hydrologic Engineering Center, <br />November 1974. <br /> <br />6 <br />
