- How to model chambers
Introduction
Manholes are used at culvert junctions to dissipate energy due to:
- Expansion/contraction of flow within the manhole chamber and outlet culverts.
- Change in direction of the culverts (i.e. a bend/deflection).
- Change in height, width or diameter and/or invert level of the adjoining culverts.
The presence of a manhole at a junction point will override the exit loss of any culvert discharging into the manhole and entrance loss of any culvert taking from our of the manhole.
There are 3 types of manholes:
- "C" for circular chambers.
- "R" for rectangular chambers.
- "J" for junctions without a chamber
