With reference to the study carried out by Rijkswaterstaat concerning the dumping of rock on geotextiles it can be concluded that both criteria (according to Lawson and BAW) in the daily design practice are most useful for the determination of the critical drop height of in bulk dumped rock on geotextiles. The criterion of Lawson is a safe lower limit for geotextiles having a low mass per unit area, while the criterion of BAW should be considered to be an upper limit. For geotextiles having a high mass per unit area this is just the other way round. The transition between the two criteria depends on the used rock grading and lies between about 300 and 600 gr/m2. The test results found by Rijkswaterstaat agree with the results found by Lawson and BAW. In practice, the critical drop height of rock in water appears to determine very well. Due to the differences between the criteria of Lawson and BAW, however, more detailed research in determining the exact criteria is needed in the near future.
