Water rivulets are produced on inclined flat plates made of high‐density polyethylene, Mylar, Plexiglas and acetate film. Conditions are obtained for straight rivulets to begin to meander and for measuring rivulets to cease their unsteadiness. These critical conditions are correlated using a one‐dimensional theory of high Reynolds number slender rivulets in which pressure gradients generated by curvature, surface tensionand contact‐angle hysteresis balance.
