At the time of writing, two test runs have so far been conducted in the field to decide which arrangement and sizes of holes collects the greatest amount of suspended sediment. 5 different variations were created.

Once a design has been decided on, the tube's ability to collect sediment will be calibrated using known flow velocities/directions and known quantities of sediment in a flume tank. Final amendments will then be made to the internal design before being deployed at some of the locations where accretion/erosion (via plates and poles) is being monitored.
