Method for determining optimal design values of flood security at the design stage of engineering systems for flood protection

The problem of increasing the efficiency of investing in flood prevention activities by improving the design solutions of protective engineering systems is considered. The effectiveness of flood control systems projects is suggested to be estimated by the value of the investment return index for the construction and reconstruction of systems. To achieve the maximum index of return on investment, the methodological basis for selecting optimal design values ​​for flood security was developed and proposed for practical use at the design stage of flood control systems.
