Abstract

Over two field seasons, we collected detrital river samples from rural Sichuan, China. Short-lived radioisotope data from the detrital samples constrains timing and magnitude of response to modern Chinese land-use policies. We used geographic information systems (GIS) as an analytical tool to calculate geomorphological change in the area. Our GIS work in one of the field areas reveals dramatic widening of the river channel in response to the largest flood in 60 years. One field area additionally allows us to constrain the relative influence of tectonics and land use on erosion.
