Abstract

In appliances for practicing aquatic sports with water flowing upwardly over a sloping bottom surface a premature breakdown of the flow caused by the accumulation of portions of water slowed down by friction at the boundary faces is prevented by at least partially removing said portions of slowed down water. This can be done by sucking off at least the increasingly portions of slowed down water which are preferably refed to a return pipe of the appliance. A further possibility provides that portions of slowed down water are accelerated by supplying water at an increased flow rate. Suction of the portions of slowed down water as well as the supply of water at an increased flow rate is particularly effected through apertures in the bottom surface in the regions in which the portions of water are particularly slowed down, i.e. above all in the regions in the vicinity of an overflow at the upper end of the sloping bottom surface.
