It was very difficult to shoot there as the waves come big and fast. You get wet there (my iPhone left its life there) so I couldn't use the tripod, it took to much time. But I needed a slow shutterspeed for the waterflow. It was a "try and error" cycle. I shot 1/10 s handheld(!) Even with sony's "steady shot inside" feature it was hard as F. In the end I did not have one single usable shot but I figured out that three shots have some usable elements. So I blended them together.
