Over the years these have canalised the water course from a multi braided to a single channel. By kick starting the process the intention is that over time the watercourse will do its own work to re-establish a natural equilibrium. In September 2012, five artificial embankments were lowered by the removal of over 900m3 of material. In stream boulders were removed and replaced with large wood structures. Additional wood structures were introduced in key locations and some of the extracted gravel was graded and stockpiled ready to be used for sediment reintoduction. Culvert pipes were removed from the floodplain and one large drainage ditch was in filled.
