ABSTRACT
The horizontal (upstream-downstream) displacement is denoted ¢(h, y). Then the modal mass is given by
At the crest the polynomial has the form
(GA)
for 0 < y < w/z at crest level. The variation of w with height was approximated as
w = hh/H (G.6) The variation of horizontal displacement with height was taken from measurements to be
The mode shape is therefore given by
