Extensive erosional gully networks are commonplace in degrading peatlands. Gullying produces local water table drawdown and the increase in drainage density associated with gully networks increases hydrological connectivity between hillslope and channel. Peatland restoration methods commonly involve blocking of gullies with peat or timber dams to limit further erosion and promote higher water tables. Blocking is also demonstrated to attenuate channel flow in peatland catchments, suggesting that gully blocks can provide Natural Flood Management (NFM) benefits. Block design can be further optimised for flood attenuation purposes, such as including an outlet pipe through the block to provide dynamic in-storm storage. This paper compares the hydrological functioning of standard peat dams and piped-peat dams optimised for NFM from neighbouring microcatchments ( |
