Description :
The potential of a high resolution multi-spectral airborne remote sensing to detect and quantify changes in channel morphology and riparian land cover are illustrated. The River Tay is a partially embanked wandering gravel bed river, and Airborne Thematic Mapper data, which collect reflectance in the visible, near, mid and thermal infrared, were acquired in 1992 and 1994 either side of a 1:65 recurrence-interval flood event. The flood event occurred in January 1993. On the floodplain, flood embankment failures resulted in fans of sands and gravels on agricultural land.
