Hydrology is not my specialty, but my understanding is that rocks prevent erosion from wave action rather than salt intrusion. If the tidal ranges of high and low are not significantly reduced by the rocks, they will do nothing to reduce salt intrusion, because salt intrusion is governed by the volume of flow in (with salty water) and out (with fresh water).
