Short term temporal variations in bedload transport rates: Squaw Creek, Montana, USA and Nahal Yatibasis of trap filling rates. The temporal nature of sediment transport in both environments is similiar, as indicated by repeated pulsing. Short term bedload fluctuations are independant of the discharge magnitude but dependant on its duration or change in magnitude.作者: KIN 時間: 2025-3-23 01:09

Luminophor experiments in the Saalach and Salzach rivers,that there adequate effective discharges occur, the transport process takes approximately one flood period.

Bedload transport and discharge in the Erlenbach stream,e number of hydrophone impulses per minute varies considerably for a given flow rate, which seems to be characteristic for the pulsing nature of bedload transport.
