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.
