Mathematical modeling of water course pollution with surface runoff from railroad tracks

Summary

The directions of railroad tracks located in the Ryazan, Tambov, Penza, Ulyanovsk, Orenburg Regions, Mordovia, Tatarstan, and Bashkiria are considered. The parameters and characteristics of the railroad tracks of the Kuibyshev railway on the section of the Samara Region: the length of the section, number of crossings with water bodies, average crossing value per 1 km, crossed water bo­dies, the length of the water flow along the railroad tracks, specific combined index of river water pollution are presented. The average value of railway crossings with water bodies in the Samara Region is 0.549/km, i. e. approximately one crossing per every 500 m. Correspondingly in every 500 m surface runoff from the road track and adjacent area enters the water body from four sides. A method of mathe­matical modeling of surface runoff from railroad bed entering water bodies is proposed provided water bodies are located parallel to transport trunk railways in the presence and introduction of previously ignored additional pollution into water bodies. The requirement for surface runoff from railroad and water body crossings treatment is substantiated.

Key words
