Canute Valentines Work Party - Part 2 Coir Matting

We are creating wide steps or terraces out of biodegradeable materials (discarded Christmas trees, rolls of coir matting, stone gabions).  The goal is to stop the river bank being eroded by the wash from passing river traffic at high tide.  These terraces progressively take the energy out of the waves so that they have little force when they reach the bank.  

These methods are ancient, but are still used today on the East coast rivers (Crouch, Colne, Deben etc.), on a larger scale than ours (see pictures and link below).  The intertidal terraces further up the Thames path towards the O2 also use similar principles.  It is called “intertidal bioengineering”. 

This year we hope to plant reeds and willow on the terraces, which we hope will stabilise them and make them last.   The coir matting should help to give a foothold to the roots.

Our neighbours in the Ecology Park have helped with advice and have offered to provide root balls of reeds for planting.
