PROPELLER JET EROSION AND STABILITY CRITERIA FOR BOTTOM PROTECTION OF VARIOUS CONSTRUCTIONS

The problem of protecting fairway boundaries against propeller jet erosion has assumed an increasing importance for the maintenance of sea and inland waterways and port facilities. Starting with methods for analyzing propeller jet characteristics in restricted water and their verification by full scale ship tests at a trial dock site with unprotected soil, this article deals with the extension of riprap protection criteria for revetments made of sand-filled bags.
