Generating Ideas • Are you sure your quick plan is the best? Let’s look closer at possible options by gathering more information ….. Links to articles, websites, video clips, interviews and images are provided in the unabridged version of this case
How Rip Currents Form Sandbar Jetty or Pier Rip currents can form when erosion creates a low point or a break in a near shore sand bar. This break makes a channel for water to rush back into the sea. These rip currents are also commonly formed along the side of a jetty, pier or groin, where the long shore current may be diverted out to sea.
List your options …(You may choose more than one option to make your initial plan) • A list of options and more links are provided in the unabridged version of this case • Record your choices under the Initial Plan area on your worksheet at: • Give reasons for your choice based on the information you have gathered.
