While the results of the feasibility research showed that no results opposed the feasibility, it was decided to have an in situ test to get final prove. In 2004 a first disposal test (500.000 m3) was executed near the Walsoorden sandbar, using a diffuser to dispose the dredged material quietly in shallow water. An intensive monitoring programme (+ evaluation criteria) were defined in collaboration with PAET to evaluate the success of the test. The monitoring consisted of MBES, tracers, sediment transport and ecological monitoring. Most of monitoring was performed by external contractors (contracts with Flemish government).

JJP was a member of the steering committee that performed the follow-up of the monitoring and the results.

In 2006 FHR evaluated this disposal test and organized a workshop where the results were presented.
