A shorter groyne will generate a smaller jet more or less parallel to the shore due to the interference with the outer uninterrupted part of the longshore current.

WebFigure 12.2. 1: Longshore Drift. 1=beach, 2=sea, 3=longshore current direction, 4=incoming waves, 5=swash, 6=backwash. As waves enter shallower water, they slow down. Waves usually approach the shoreline at an angle, with one end of the waves of the train slowing down first. This causes the waves to bend toward the beach.
