ASSESSMENT OF WEIGHT OF SEDIMENT FORMATION DEPOSIT IN MUNICIPAL COLLECTOR SYSTEM (MCS)

Abstract

The main purpose of this work is to provide calculations of annual weight of sediment formation deposit in Municipal Collector System (MCS). The article considers two-phases flow in the collector. The storm water collector is small culvert for storm water (rainwater) or for removing the river (creek, stream, flow) underground. The article defines the solid particles in flow as sand, clay, stones, silt, etc. It was found that in case of signif\icant flow rate, then all solid particles move in the pipe. If not, they settle to the bottom and sediment is formed. In this paper, total weight of sediment formation in Moscow collector system is calculated at average annual values. On this ground a consideration can be made that sediment deposit reduces efficiency of the system partially or completely.
