RESEARCH OF SYSTEM OF JOINT REMOVAL OF SUPERFICIAL AND DRAINAGE WATERS FROM CITY TERRITORIES
Description
In the article substantive provisions of the offered system of drainage storm waters removal are reflected. Dependence for calculation of residual values of the weighed particles in a stream from speed and time of movement of drains is established and optimum parameters of the tank-sediment bowl are defined. The technique of forecasting of quality of water in drainage storm system with due regard for diluting both storm and thawed snow drainage waters and processes of physical and chemical and biochemical self-cleaning is developed. Eco-economic efficiency of system is defined
