FIELD ASSESSMENT OF SEDIMENT TRAPS - Texas A&M University (TAMU) Scholar

Sediment traps whose particle collection abilities had been calibrated in a laboratory flume at velocities of 0, 4, and 9cm/sec were deployed in natural bodies of water to intercalibrate larger traps under current conditions ranging from tranquil to over 20cm/sec. For cylinders, the height to width ratio is the controlling factor of the mass of sediment collected. Traps can be scaled up in size and maintain a similar (though not necessarily correct) collection rate. Increasing current velocity will alter the collection rate of a trap in a manner which depends on the trap geometry. The size distribution of particles collected in traps is biased by trap geometry with over-efficient traps collecting more fine particles. -Author
