Going with the Flow – tides and the Deben Estuary

In October 2019 over 1500 visitors came to an exhibition in the Longshed about tides.  Many people commented that there should be a permanent record of the exhibition.  This page provides links to downloadable pdfs of 31 of the 33 boards that were on display.  All of the boards from the exhibition are available to local schools and other organisations on loan – please email woodbridgeriversidetrust@gmail.com if you are interested in borrowing them.

We are grateful to Dee McLeavy who co-ordinated the original exhibition and to the many organisations and individuals who have given us permission to make this information available. The exhibition was sponsored by the Suffolk Coasts and Heaths AONB, the Institute of Physics, DanceEast, the Arts Society Woodbridge and local businesses.

Care was taken to check the information in the exhibition – our apologies if you spot any errors.  Any opinions expressed are not necessarily the opinions held by Woodbridge Riverside Trust.
