Experimental studies in the field of storm water drainage

Abstract

The article describes the conducted experimental studies of surface runoff that fall into the storm network. The rest of the water is trapped in the unevenness of the soil, in the grass cover, partly seeps into the soil, and partly evaporates. Therefore, in order to determine the actual amount of water entering the network, a special correction factor ( ϕ < 1), called the surface runoff factor (or simply the runoff factor) should be introduced when determining the estimated flow rate. The obtained flow rates are compared with those calculated for different flow conditions (gradients, surfaces, etc.) based on general hydraulic formulas.
