Getting Smart about Rip Current Education and Data Collecting

Stevens Students Develop App for Saving Lives

5/31/2012

Sandy Hook, N.J. – The arrival of Rip Current Awareness Week on June 3, 2012 will help remind people that rip currents are potentially one of the deadliest natural phenomena.  However, they tend to receive far less publicity than other natural hazards because our understanding of them is still somewhat limited. 

This summer, Stevens Institute of Technology and the New Jersey Sea Grant Consortium (NJSGC) hope to change that by utilizing mobile device technology to collect and distribute up-to-the-minute rip current data and related information.

Under the supervision of Stevens Professor David Klappholz, Class of 2012 Computer Science graduates Christopher Seeley, Ralph Mattiaccio, Ken Bodzak, Will Abeel and Danielle Maginnis have developed a smartphone app for multiple platforms to assist lifeguards with identifying and cataloguing rip current occurrences on their own beaches, while giving them a glimpse at what neighboring communities are experiencing in real time. Developed at the request of NJSGC’s Coastal Processes Specialist and Stevens Professor Jon Miller, the app could prove invaluable to both local lifeguards and the National Weather Service (NWS).

The NWS plans to use the collected information to evaluate its own rip current forecasts. The information will also help refine current understanding about when and where rip currents occur and under what conditions they are most prevalent.

The concept is fairly straightforward.  A lifeguard with a smartphone in a participating community can travel down the beach and stop when a rip current is identified.  Using the app, the lifeguard will enter basic information about the rip current (approximate size, strength, adjacency to a structure, etc), and record its location using the phone’s built-in GPS. Lifeguards can also use the app or the web-interface to keep track of rescues via a free-form description field.

An additional web interface enables lifeguards to view all of the reports from the previous 24 hrs in either a list or map form.  The map form utilizes Google Maps and displays basic information about the rip current.  All of the information is displayed in real-time so that lifeguards know what’s happening in adjacent communities.  The website is optimized for display on a mobile device so information can be viewed on the same platform on which it’s entered.

A demo of some of the capabilities of the system has already proven successful.   Currently, the mobile-optimized website allows authenticated users (lifeguards) to enter basic information about the identified rip current.  The application then populates a database with the entered information as well as relevant related data drawn from NOAA databases regarding the waves and tides at the time of the report.  All of this is happens in real time and is searchable by other lifeguards, the NWS and the research community. 

Miller hopes to get the project piloted in one or two shore towns early this summer. 

A press conference and demonstration is planned for Wednesday June 6 at 10:00 a.m. in Spring Lake, N.J., one of the first New Jersey beach communities to test/use the mobile application. Details to follow.
