mhabich Posted February 8, 2019 Share Posted February 8, 2019 Waves, tides, and currents: the kayaking environment Sunday, February 17 - 11 am to mid afternoon - REI Community Room, Reading MA We’ll learn the physical causes of waves, tides, and currents, and might find out: Why do waves come in sets? Why are the waves on some beaches always dumping? Rip current…friend or foe? Why is the water so rough around headlands? Why does a 12 second wave have 4x the energy of a 6 second wave? Why is the tide 50 minutes later each day? Why is there a bigger and a smaller tide each day…sometimes? Why are the tides so big in the Bay of Fundy? Lots of drawings and graphs, few equations (all avoidable). After the presentation we’ll have an open discussion of strategies to deal with waves and currents as a kayaker, where to get predictions, and rules for interpolation. This event is open to paid club members only. Please RSVP on the club calendar here. Link to comment Share on other sites More sharing options...

Dan Foster Posted February 10, 2019 Share Posted February 10, 2019 I'll be there, and I hope others join as well, because it's fun to find out what makes an ocean wave wave. Link to comment Share on other sites More sharing options...

Inverseyourself Posted February 11, 2019 Share Posted February 11, 2019 I’m working that day. Will you publish written material, Mike? Very interested! Link to comment Share on other sites More sharing options...
mhabich Posted February 11, 2019 Author Share Posted February 11, 2019 I have an extensive slide show, but it would make little sense standing alone. No written handouts. The reference I used most and would recommend was Waves and Beaches, by Willard Bascom, revised edition 1980. It can be found through Abe or Amazon, typically as a library discard. Waves, by Fredric Raichlen, 2013, MIT Press, is concise and worthwhile. Past that, I stole from every source available. Link to comment Share on other sites More sharing options...
