| Abstract: | The aim of this technical note is to introduce a new, simple construction of a buoy-carried, suspended sediment trap that
meets given demands concerning design (geometry of vessels) and stability during the registration period. The device is based
on a ball-and-socket joint in the center and two Plexiglas cylinders (D=5cm, H=30cm) on PVC plastic arms. The suspension consists
of only three parts. To determine the optimal construction, the apparatus has been calibrated in a circulating flume at various
water velocities. |
