Storm Sewer Junction Hydraulics and Sediment Transport
Stormwater can carry substantial loadings of suspended solids into storm sewer systems. A potentially important issue associated with sediment transport through sewers is "shock loading." This occurs when periods of low flow leave significant sediment deposits in sewers and manholes. A large event can then provide the energy to scour the deposited material and transport far more loading to a receiving waterbody than is generated from the land surface during the event. This could be a potentially critical issue in developing TMDLs since loading might be far greater than expected for large events, and lower than expected for small events. This paper will present the results of significant physical modeling research on energy losses associated with manholes and discuss how these losses might effect sediment transport. Additionally, a 3-D hydrodynamic model was applied to various manhole configurations to qualitatively assess circulation tendencies and sediment movement within manholes.
