摘要：

Two self-buoyant sediment traps using straight cylindrical sediment collection vessels have been designed and tested. The constructions are hydrodynamically stable and the vertical alignment of the sediment collection vessels are retained both in laminar and moderately turbulent water currents with flow rates up to 40 cm s-1 for the nondisplacing, and at least up to 45 cm s-1 for the displacing sediment trap type. Both constructions are simple and easily handled in the field. © 1990.
