Here is a great web site showing before and after picture of Hurricane Sandy - just move the slider across these images and you will see exactly what damage Sandy has caused. Apart from the flooding and destruction that is immediately apparent, from a coastal geomorphological point of view it is of interest to note that, in general, the actual beach has not undergone much change, but that there was signifcant onshore transport of sand onto roads, car parks, etc. We'll go into this in more detail during the barrier lecture after the class test, but the key message here is that big storms move sediment onshore, rather than offshore.
