Inlet beaches can change a lot near the mouth, but little up-inlet where the effects of winds and waves are usually much less significant. In spite of this and the fact that Sound beaches have been reshaped in many places, they continue to change a lot less and less frequently than south shore inlet and ocean beaches. Now, due to this instability, even average nor’easters produce changes and erosion. The severe damage from that storm changed the dynamic effects of tides and waves along Long Island Sound beaches and opened the flood gates to frequent changes, because the long-term stability had been altered. Sound) and very high moon tides also pushed water so high on the beaches they eroded them in places that waves never touched before. The combination of sustained high east winds, huge waves (for L.I. But, during that storm relentless strong waves moved giant boulders, seawalls were damaged and sand was pulled off the slopes of the beaches. In fact, until the great blizzard of January 1977 featuring strong winds with gusts in excess of 70 mph for two days, L.I. ![]() Sound beaches change the slowest and the least over time because the beaches are dominated by large boulders, pebbles and coarse sand. Some valuable insight into the dynamics that cause both subtle and dramatic changes to our Island’s shorelines.įirst of all, all beaches change, but some change more drastically and/or faster than others. After, the sand that was there partially filled the trough and moved to the west. Before the storm sand extended to the slope of the beach from the high point. ![]()
