Generally:
Channel complexity reduced by continuous down-cutting of riffle surface. Bed uniformly coarser. Pools make up < one-quarter of the channel length. Pools are uniformly shallow with only rare pools exceeding 0.25 m in depth. Channel bed has exposed bedrock over significant lengths of the reach. |
