WebHydroplaning. Hydroplaning occurs when the drainage capacity of the tire tread pattern and the pavement surface is exceeded; water builds up in front of the tire and creates a water wedge which can lift the tire off the pavement, thus reducing the tire/pavement friction to zero. Hydroplaning is a function of the water depth, roadway geometrics ... WebThe efficiency of a grate is dependent on the same factors and total flow in the gutter.
