Abstract

An automatic Birkbeck-type recording bedload monitoring station has been established on the ephemeral Nahal Yatir, a gravel-bed stream that drains part of the semiarid northern Negev Desert. Bedload discharge is determined independently, synchronously and continuously by three slot samplers that are set at intervals across the channel and lie flush with the stream bed. Water-stage and water-surface slope are also measured continuously, all data being stored conveniently in digital format on a solid-state logger. Bedload has so far been recorded for four flash floods, revealing a peak flux-rate in excess of 10 kg m-1 s-1, which is more than threefold the highest rates recorded in any river to date, and gives a glimpse of the reasons why bedload sedimentation is a particular nuisance in the world's drylands. -Authors
