I am analyzing a SW management plan done in ICPR and I the outlet rating curve for a box culvert is not matching up with a reating table I computed using Culvert Master. (The ICPR flows are significantly higher for all stages >10% higher)
I have doubled checked all input parameters and everthing is consistent between the 2 models (ICPR and Culvert master). Mannings N, inverts, length, entrance and exit losses, wingwall shape and angle, bevels, etc....
Anyone know what methods ICPR uses to determine culvert rating curves? I need to know where these numbers are coming from.
I'm not saying that anything is wrong, just trying to verify the info before issuing a response to a client.
