Abstract
Terrestrial photogrammetry and reflectoriess electronic telemetry were tested as measures of erosion in a first order catchment cut into marl bedrock at Draix (Southern Alps, France). These methods have been used to evaluate precisely (≤ 1 cm), by periodic survey, the amount of slope changes, without disturbing the environment. The mean annual volume of erosion has been estimated from these data and compared with measurements of bed and suspended loads of the stream.
