Culvert diameter affects both the water flow capacity and the number of grid cells allowing passage across it. The greater the culverts diameter, the more cells are considered to be part of the entry- and exitside of the culvert. This cell count is determined by the CULVERT_DIAMETER attribute. If the CULVERT_DIAMETER attribute is > 25m, the amount of cells has reached a maximum and does not increase anymore.
Notes
- A culvert is identified as a rectangular (box) culvert when it also has the Culvert rectangular height key set to a non-zero positive value. In such situation, the diameter is interpreted as the width of the cross section of the rectangular culvert.
