Preliminary Experimental Tests Of Local Erosion
At River Piers With A Particular Shape

Abstract
In the present study early experimental tests concerning local erosion phenomena
have been carried out on a particular shape of the already effective circular piers
in order to determine if any improvement is verified in their shape coefficient
(with a corresponding decrease in scour). In particular, the circular pier
foundation has been shaped as a truncated cone, partially or totally sunk into the
mobile bed. In the experimental tests a preliminary comparison has been effected
between scour at uniform circular pier and non-uniform piers with two different
values of bevel angle β for the truncated cone foundation. Experimental results
have shown that, for both values of β, the scour depth has been lower than that
identified in experimental tests conducted on circular piers of the same diameter
but without the truncated cone foundation. This interesting results open up an
encouraging research field.
