A New Technique for the Automatic Monitoring of Erosion and Deposition Rates

摘要: The rates and processes of erosion deposition soils sediments are subjects widespread increasing concern in the Earth environmental sciences. Process inference from field studies, however, has been hampered by a lack information on precise magnitude, frequency timing erosional depositional activity, because no automatic monitoring technique hitherto available. I describe here an Photo-Electronic Erosion Pin (PEEP) system which, apparently for first time, allows quasi-continuous time series data to be collected. Example results river bank site show how PEEP helps define true temporal distribution geomorphological change, quantify impact individual forcing events, discriminate between competing hypotheses process control contexts. should thus allow more effective testing models high resolution facilitate rigorous linking catchment sediment output supply dynamics.
