Under partially wetting conditions, the rear of drops sliding down an inclined plane develops, above a critical velocity, a cornered singularity which is rounded at small scale. The inclination or the curvature of the contact line delays the wetting transition. At higher velocities, a liquid rivulet, whose width increases with the velocity of the drops, develops and breaks into smaller drops deposited on the substrate. A lubrication model accurately describes several aspects of these phenomena: conical interface, delaying of the dewetting transition, width of the rivulet... If the flow rate is increased, the liquid flows as a straight rivulet and above a critical flow rate, it destabilizes into stationary meanders. The balance between inert...
