For Initial Conditions 1D, InfoWorks ICM seems to specify 1) initial level(m AD) and inflow values at nodes for Nodes grid, 2) and initial depth (m) and flow values along the river reach for River Reaches grid. For river reaches grid, as an initial condition, I would like to assign (water surface) level values too. That is more easy to set up, and seems to be sensible especially for natural river profile with a lot of bottom level undulation.
