Stack height estimation

This tool allows to estimate the stack height needed to respect a specified odour criteria at ground. It also takes into account, in a simplified way, the height of the terrain surrounding the stack, or a nearby building within a radius of ten stack heights.
This procedure can be applied to simple situations, while complex orography and/or the presence of many buildings require to carry out a dispersion modelling study.

Odor concentration at emission (OU/m3):
Volumetric flow rate at 0 C and 101.3 hPa (m3/s):
Allowed odour concentration at ground (OU/m3):
Rising terrain height (m):
Building length (m):
Building width (m):
Building height (m):
