Results of evaluating the effectiveness of mechanisms for eliminating flooding of territories by surface wastewater
Hydraulic calculation of surface runoff drainage systems according to regulatory documents is not carried out for the heaviest rain, as this will lead to an overestimated cost of the network, but at the same time flooding of the territory may occur in the catchment areas. Two types of flooding formulations proposed by M.V. Molokov, who point out the importance of choosing a period of one-time excess of the calculated rain rate when calculating the network. A total of 114 basins were analyzed taking into account different return periods. Based on the results, the definition of the coefficient k_v of the use of the regulating volume is introduced. The characteristics of 4 typical development zones are formulated and the analysis of the efficiency of the coefficient k_v of using the regulating volume for these zones is carried out, with the presentation of the results.
