  • Losses – fixed, Englehund, automatic manholes etc
  • Mitch’s J-type manhole (see TUFLOW forum)
  • 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
