Flood Management (or flood risk management) concerns all actions related to the control of floods, the mitigation of flooding and, after such flood control and mitigative measures have been implemented, the management of the residual risk of flooding. In order to decide on an optimum solution of flooding problems, it is necessary to know the extent of damage caused by floods of different magnitudes/probabilities. A logical method of assessing such damage for use in the selection of a flood protection system is presented in this Manual. An effort has been made to formulate recommendations for the application of a certain return period as a function of the considerations mentioned in the Manual. Advantages and disadvantages of a standard level of protection have been mentioned. Reasons for adopting a certain level of protection for a certain area (such as loss of human life), has been discussed including related political, economic or psychological considerations. Further, the use of hydrodynamic mathematical models of the deterministic type for carrying out flood management has been described. The purpose and effectiveness of certain mathematical models for understanding the flooding phenomenon for studying and testing flood control measures and, finally, for calculating various flood parameters has also been described. In all, this Manual covers all management strategies for flood mitigation involving structural approaches and complements ICID?s Manual on Non-Structural Approaches to Flood Management.
