double diffusive_slope_singularity_protection =1e-4

Protects diffusive Saint-Venant equation from numerical problems for slope ≃ 0.

For diffusive St. Venant equations, near to zero, the driving force is sqrt(|h1-h2|). For h1 ≃ h2, the sensitivity of the flow has a singularity. To avoid this near to the slope zero the driver is overrriden by |h1-h2|. "Near" is defined by this constant.
