RECHERCHES SUR LE COMPORTEMENT HYDRAULIQUE DES DEBRIS ORGANOGENES

Authors


SUMMARY

Presentation of investigations on the hydraulic content of fragments of lamelli-branches dredged on the continental shelf (diameters between 12 and 0.51 mm).

These lamellar fragments have fall velocities greatly different from those of quartz grains with which they are able to coexist in a sediment. The data of G. Rittinger (in TRASK, 1939) and R. W. Budryk (in TRASK, 1939) are not applicable to these fragments.

The author points out the interest of a basic documentation for the dynamic study of sedimentation.
