- * Friction laws calculate the stress between the flowing fluid and the bottom,
- * which is called bottom shear stress. The bottom shear stress is
- * needed to calculate on the one hand the loss of momentum due to
- * bottom friction and on the other hand the bedload transport rate.

  * A LET mobility model of Lomeland et al. 2005 \cite Lomeland2005 can be used to add an
  * artificial water depth to limit the friction for small water depths.
