JUSTIFICATION OF FORMULAS AND THEIR PARAMETERS FOR THE OPTIMIZATION CALCULATIONS OF RAIN SEWER NETWORKS

The working conditions of the network of rain sewerage and existing methods of their calculations are analyzed. The reasons of inundation and flooding of urban areas of rainwater because of imperfections in the rain sewer networks are estimatad. The present article deals with the necessity of studying of network between themselves and with regulatory structures that are connected to the wastewater system. This requires improvements and optimization of hydraulic calculations of all rain sewer networks, taking into account pressure head operation of mode sections. The type formulas for these calculations and numerical values of their parameters are estimated. The article discloses comparison of simulation results obtained from the Pavlovsky's and Fedorov's formula that Ukrainian existing standards are recommended. Optimization and hydraulic calculations based on the proposed formula and numerical parameters obtained for this formula are justified.
