SEDIMENT TRAP DYNAMICS AND CALIBRATION - A LABORATORY EVALUATION Academic Article uri icon

abstract

  • The flow dynamics and particle trapping characteristics of several designs of sediment traps were investigated using dye, sea-water, and deep-sea lutite in a recirculating flume and fish tank at velocities of 0, 4, and 9cm/sec. Particles are collected through a process of fluid exchange rather than falling freely into a trap. Cylinders trap particles in the closest agreement with the sediment depostion rate in the flume. Funnels generally undertrap, but their efficiency may be improved by constructing a baffle at the top of the funnel. Containers with narrow mouths and wide bodies consistently overtrap at an unpredictable rate of many times the actual vertical flux of particles. -from Author
