Q. Can you explain Permeable Spurs?

A permeable spur may be constructed by driving two or more rows of bally piles with sufficient penetration below riverbed level to provide adequate grip during floods. Cross braces and longitudinal runners or waling pieces may be provided to strengthen the structure. Stays may be added on either ends so that differential pressure and flood attack can be withstood. The structure may be filled with brush wood and weighed down by stones.
