Sediment deposition in storm drains is one of the most common problems affecting the hydraulic behavior of sewage systems. Sediments are deposited with the passage of time and in the time of drought in particular, the long-term retention of sedimentary solids in the sewer increases the risks of changes in sediment, uniformity and cohesion as the sediments change the surface roughness of the pipes and reduce the flow capacity and change in velocity. In this study, the characteristics of storm sediments were studied in the center of Ramadi city, where 6 samples were collected from rainwater collection holes (manholes) and the main collection basin from three rain networks in different areas (Al-Moalemeen neighborhood, Al-Malaab neighborhood and Al-Shurta neighborhood) and they are of a separate type. It is not hydraulically connected to the sewage network. The samples were examined in the laboratories of the University of Anbar - College of Engineering and included particle size distribution, average particle size (d50), specific gravity (Gs), moisture content and organic content. The sedimentation analysis results showed that sand was the main component except for one sample in which gravel was the main component, and clay and silt were minor components in the samples. High organic content was found in two samples, indicating an overrun on the network. [ABSTRACT FROM AUTHOR] |
