11. Backwater and Surcharge Orifice The scattergraph show here reveals the presence of a dead dog and a downstream restriction that cause backwater and surcharge […]
10. Backwater and Surcharge Most surcharge conditions result from downstream restrictions that reduce sewer capacity. The flow monitoring data shown here indicate that this sewer […]
09. Surcharge Surcharge conditions are common in sewer systems, especially during wet weather event. The flow monitoring data shown here indicate that this sewer operates […]
08. Debris Amusement The scattergraph depicted here reveals shifting debris that reduces the pipe capacity at this monitoring location. The iso-Qs depict the average daily […]
07. Iso-Q Lines The relationship between flow depth and velocity is important to understanding the hydraulic conditions in a sewer. The addition of flow rates […]
