Abstract
Runoff from peat land is supposed to be dominated by surface and near surface flows causing large flood peaks. However, Waunafon's degraded valley fen peat moorland includes organic layers up to 0.5m deep that are unsaturated in summer. So while, overland flow may be affected by rainfall onto saturated ponds, runoff in soil pipes, and through channel incised between the tufts of heath, this degraded peat land has a significant storage capacity in summer and commensurate capacity for seasonal flood attenuation.
