how does water flow around three obstacles in a triangular formation?
a) the water flows between two obstacles and strikes a third obstacle standing behind them: a large cavity develops between the obstacles, for the water forces itself through the first two obstacles and then strikes frontall the obstacle behind. the deep cavity is caused by both the impact as well as the narrowed channel of current.
b) behind the obstacle which the water first strikes there are two further obstacles: no large cavity is created between the obstacles, since the hollow cavities form in front of individual obstacles and the first obstacle weakened the impact of the water against the subsequent obstacles.
