Hello Hec Ras Community

I´m currently working on a 2D unsteady flow Modeling for which I´m using LIDAR-data to create a DEM but for more accuracy I want to add groins (made of stone) which are situated laterally to the flow and represent a barrier.

My question was now HOW to best model this lateral obstacles for which I don´t have accurate dimensions?

I would appreciate any advice

thank you

I would model all of them as weirs. The weir coefficient should be adjusted though based on the submergence that the finger would go through
