Flood control reservoir systems are designed to reduce the intensity of flooding in flood plains to acceptable levels. Planning flood control reservoir systems requires analysis of basin-wide hydrology, individual reservoir and system operation, and system performance in reducing intensity of flooding. Sizing reservoir systems system formulation includes the major tasks of selecting system components from among competing alternatives and determining the flood control storage within each reservoir. Selection of system components configuring the system is the key element in the analysis. This paper focuses upon reservoirs as flood control measures, but it should be emphasized that non-reservoir measures, such as levees and channel work can form invaluable system components. Analysis of the performance of alternative flood control systems is greatly complicated by the system interaction that can occur among system components. One of the important interactions in a system occurs when a number of reservoirs are being operated for common locations and are thus able to take advantage of inflow and release timing effects. Because of the large number of alternative systems possible in complex river basins and due to the complexity of evaluating each system, it is essential that a reasonably structured system formulation strategy be adopted as the framework for analysis.
