A grass chute is a relatively short, steep earthen channel arrangement that involves excavation works to reduce the slope (battering). The works usually occur at a head-cut or knickpoint feature associated with channel/floodplain deepening processes. The reduced slope chute improves bed slope stability, riverbank stability and creates more favourable conditions for vegetation establishment. Vegetation may comprise native and/or introduced species, however, native species are often preferred as introduced species risk becoming invasive weeds. A suitable vegetation composition may include grasses, rushes, reeds and/or shrubs.
