Abstract

This study examined the temporal dynamics and longitudinal distribution of wood over a multi-decadal timescale at the river reach scale (36 km) and a meander bend scale (300-600 m) in the Ain River, a large gravel-bed river flowing through a forested corridor, and adjusting to regulation and floodplain land-use change. At the reach scale they estimate wood production to the river from the riparian forest by bank erosion over a six-decade time period, and describe the distribution (longitudinal and cross-sectional) and abundance of wood over a ten-year period. At the sub-reach scale, they describe the change in wood distribution and mass over a ten-year period. The increase in wood since 1950 is a response to floodplain afforestation, to a change from braided to meandering channel pattern in response to regulation, and to recent large floods. The results, and the link between sinuosity and wood frequency, establish geomorphology as a dominant wood storage and recruitment control in large gravel-bed rivers
