TUFLOW 1D Channels and Hydraulic Structures: Difference between revisions

A scruffy dome is a type of dome inlet screen placedinstalled over a drop inlet, commonly used in stormwater systems. These inlets can be modelled in TUFLOW using a 1D Q type pit with a depth-dischargedepth–discharge curve that representsreflects the hydraulic performance of the dome.

The Queensland Urban Drainage Manual (QUDM) recommends using the lesser of the weir flow or orifice flow equations to define inlet capacity (see Section 7.5.4). A blockage factor is also recommended to account for potential debris build-up during flood events (see Table 7.5.1 Provision for blockage at kerb inlets). This factor may vary depending on local guidelines, so it’sregional worthstandards checkingshould yourbe regional standardsconsulted.
