Q. What do you mean by Depth of Scour?
The maximum scour depth in a stream can be ascertained when ever possible by actual sounding at or near the site proposed for the bridge during or immediately after a flood. Before the scour holes have had time to silt up due to allowance should be made in the observed depth for increase in scour resulting from-
Where the above practical method of determining scour is not possible the following theoretical method may be used as a guide when dealing with natural streams is alluvial beds.
D = 0.473 [ Q / F ]?
Where D = Depth of scour below HFL for regime conditions in a stable channel in meters.
Q = Design discharge in cumecs.
F= Silt factor = 1.76 √m , m is the mean diameter of particles in mm.
Q. Holes in steel plates connecting to H-piles There are two types of holes present in the steel plate associated to H-piles in the pile cap. The first type of holes is design
