A quick way to check whether a river bank is connected to 2D

Occasionally we get models sent to the support team where the river banks are not correctly or completely connected to the 2D domain which represents the out-of-bank flow.  The following theme will allow you to theme those 2D elements which … Continue reading

Don’t forget your 2D Initial Conditions!

A couple of recent 2D models have been seen where a tidal boundary is being represented and results on the 2D mesh show water surface elevations greater than the tidal level…this is due to poor model schematisation and in particular the … Continue reading

2D Suspended Sediment Modelling in Infoworks ICM

In version 5 of Infoworks ICM it is now possible to model suspended sediment transport within the 2D domain.  This uses the current advection-dispersion model which is already implemented in the 2D engine.  The 2D sediment functionality will also calculate … Continue reading
