In previous work we investigated rivulets running over and under an inclined plane and discussed their global properties as functions of the contact angle and the volumetric flow. Here we derive scaling laws for these properties in the limits of very small and very large volumetric flow. We compare these scalings with the exact numerical results as well as with those obtained by means of the lubrication approximation.
