Several fathometric surveys conducted in recent years showed a large depression or scour hole on the downstream southeast corner of the central pier of the Castleton Bridge over the Hudson River in New York. This paper attempts to evaluate the causes of the existing depression or scour hole as well as to ascertain the possibility of its enlargement or migration upstream.
