Essex Rivers Hub

Woody debris installation, Wickford Memorial Park

The river Crouch flows through Wickford Memorial Park which is a popular open space for local people within the urban area. The river itself has little in-channel variation resulting in relatively steep banks with almost uniform width and a straight channel.

In Autumn 2014 the Environment Agency began work to add some in-channel habitats by installing woody debris. This involved removing some small trees from within the Park, these were then angled downstream, embedded into the bank and secured to the river bed using wooden stakes to ensure they remain in place and do not become dislodged and float downstream. These will act as flow deflectors, changing the flow of the water so that the opposite bank will begin to erode and the silt will deposit behind the deflector.

This changes the structure of the river creating a more natural shape and also creates changes in the water flow around the deflectors. This will establish a variety of habitats that will suit a wide variety of species.
