Description

Willow Spiling
Willow spiling has been used as a riverbank erosion control method for many years. Willow is very versatile due to its amazing ability to regenerate from cuttings and branches. Live willow Spiling are ideally suited to large river channels and can provide riverbank stability with high biodiversity value. Willow spiling is a traditional technique which should only be used in low energy situations, but is a good method of retaining vertically eroded riverbanks in areas where regrading the bank is not possible.

 

 

Live Willow Brush Mattress
A live willow brush mattress is capable of withstanding very high flow velocities and is therefore suitable in higher energy, mobile gravel bed rivers. The branches absorb flow energy, trap sediment and seed and as a result evolve with high biodiversity value. River scale flume trials undertaken in Austria demonstrated that this revetment, with one season’s growth, could withstand velocities over 5 m/s.  

 

 

Living Root Wads
Whole willow tree roots, also known as Root Wads, can be used to function as a both a living revetment and as woody debris. We can advise on the riverbank stability and ecological gain of such techniques.
