Log transport and deposition in incised, channelized, and multithread reaches of a wide mountain river: Tracking experiment during a 20-year flood
文摘
Large wood dynamics during a 20-year flood in a wide mountain river was investigated with radio transmitters. Median displacement length of tagged logs in the incised and channelized reaches was 8 and 5 times greater, respectively, than in the multithread reach. Flood-peak flow conditions were modelled for the cross sections with deposited logs and without wood deposits. Hydraulic modelling allowed us to explain differences in wood behaviour between distinct channel morphologies.
