linearised bottom friction coefficient? what is it? - D-Flow Flexible Mesh - Delft3D
intro story D-Flow FM
D-Flow Flexible MeshD-Flow Flexible Mesh (D-Flow FM) is the new software engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. Together with the familiar curvilinear meshes from Delft3D 4, the unstructured grid can consist of triangles, pentagons (etc.) and 1D channel networks, all in one single mesh. It combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration, resulting in:
An overview of the current developments can be found here. The D-Flow FM - team would be delighted if you would participate in discussions on the generation of meshes, the specification of boundary conditions, the running of computations, and all kinds of other relevant topics. Feel free to share your smart questions and/or brilliant solutions!

Greetings,
I downloaded the model demo of Wind driven channel flow .In the measurement file,there is a analytical solution equation.

I could not understand the 'linearized bottom friction coefficient'.Its unit is m/s.Usually,friction coefficient is dimensionless.
Thanks for telling me what it is and how to calculate bottom friction ? with it. Any feedback will be very useful.
