open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi there,

I have read through the forum to find similar topic but cannot find anything the represents my query.

I have two inflow boundaries - one has a BOTTOM elevation of around 60m (Boundary 2), whereas the other is around 52m (Boundary 3). My outflow (Boundary 1) is 47m.

I am wondering how best to initialize my simulation? I had originally set my INITIAL ELEVATION = 60m, however this results in a dry area upstream at Boundary 2.

I have a Free Surface elevation of around 63m at Boundary 2 from another model (LISFLOOD) i am calibrating this one against. Is this a suitable INITIAL ELEVATION? or does an elevation of 63m vary too much from Boundary 3?

What is the best way of approaching this?

Kind Regards,

David

Hello

If you have big differences in bed elevataion between upstream and downstream, constant elevation initial condition is not te smartest way to do.
If you have an existing solution, you can interpolate it directly on the Telemac mesh. Otherways, you can start with what I call "Warm Start". This means, you generate an restart file with Blue Kenue. This file contains at least a layer of bed elevation and water depth. The water depth can be constant (1m) only at the main channel of the river and nil elsewhere.

with my best regards
