  • A design for a sediment flux sensor is provided for use in sedimentation studies in lacustrine and shallow marine environments. The sensor utilizes an optical system to measure sediment accumulation with a data logger. Unlike other passive
  • or mechanical sediment trapping systems, the sediment flux sensor records the time of deposition precisely and therefore is useful for investigating the linkages between external processes (hydrological) and sedimentation.
  • An inexpensive turbidimeter for monitoring suspended sediment
  • Fluid flow and sediment transport processes in geomorphology : innovations, insights, and advances in measurement
  • This paper details the design and performance of such a turbidimeter (the HOBS Harry's Optical Backscatter Sensor) developed for spatially distributed monitoring of suspended sediment in proglacial streams. The effectiveness of the HOBS
  • in determining suspended sediment concentration is determined using bulk field sediment in the laboratory, and its field performance assessed from a network installed for one ablation season in 2 proglacial streams at Small River Glacier in the Canadian Rockies.
  • Measuring flow velocity and sediment transport with an acoustic Doppler current profiler

  • and Lillooet Lake in western Canada. The paper will demonstrate that aDep offer many advantages over traditional measurements of velocity and sediment transport, but will highlight some serious limitations that require both consideration and development

  • This paper reports on an analysis of instantaneous sediment transport in relation to wind gusts, moisture content and fetch length from a field study carried out at Skallingen, Denmark. Wind speeds were measured with cup anemometers
  • and instantaneous sediment transport with vertical traps coupled to electronic balances. The experiments have been designed to measure sedimentary processes in the nearshore, beach and dune systems and to develop a better understanding of the controls of the beach
  • and dune sediment budgets : wind speed, surface moisture conditions.
  • Physical and logistical considerations of using ultrasonic anemometers in aeolian sediment transport research

  • Fluid flow and sediment transport processes in geomorphology : innovations, insights, and advances in measurement
  • The Fryberger model uses standardized wind data to estimate regional aeolian sediment drift potential (DP), which allows for interpretation and classification of aeolian dune landscapes. This paper identifies systematic frequency and magnitude
