Models of storm water drainage from roads
In this paper, the drainage of storm water from traffic roads is analysed by analysing the traditional method of drainage using a separate sewage system, and also by analysing the integral approach to the drainage of rainwater in the urban area. The research objectives for the treatment of the topic in this paper are set and processed for the needs of planning and development of the sewage system for the drainage of rainwater from roads in urban areas, as well as for the evaluation and ranking of conceptual solutions and the elaboration of plans for the general solution for the collection and drainage of surface water from roads. For relevant rain episodes, i.e. rainfall of appropriate duration and intensity, runoff coefficients and flows were considered and analysed according to the rational method, all for the purpose of obtaining data on the amount of rainwater entering the sewage system. According to the set research program, it was necessary to work on defining and establishing the amount of precipitation for the area that was the research polygon, and based on exact measurement data, the optimal transverse and longitudinal drops of the level of the road were determined in order to drain rainwater from the roads as efficiently and quickly as possible, within the framework of the rules that define this area.
