You guys must not surf. I worked on the beach in front of the Sheraton hotel and the Out rigger reef as a surf instrutor beach boy digging trenches to slow the waves down and redirect it somewhere safe. Its a loosing battle. What mother nature wants she will have. If the Hotel owners and politicians listened and not have built so close to the high water mark we wouldn't be having this problem.  If the water is that high on the surface then underneath the ground it's much more worst then you think. Now their in panic mode. Talk of building a T-shape groin fronting Royal Hawaiian and Sheraton hotel " wrong, " tear down the old groin and pray.
And stop building on the beach. The beach belongs to all to enjoy freely
I'm no scientist but I do love to surf.
