where
VM = volume of cap material over dredged material mound
VCA = volume of material in cap apron
tc = thickness of cap
tta = thickness of cap at toe of mound apron
rM = radius of overall dredged material mound
rTC = radius of total capped surface
For a uniformly thick cap on an elliptical mound, the following methodology
is given to calculate cap volume:
tc ( r1 r2)

[ (r1 r2 )TC

where
VM = volume of cap material over dredged material mound
VCA = volume of material in cap apron
tc = thickness of cap
tta = thickness of cap at toe of mound apron
r1 , r2 = long, short radius of ellipse
= subscript for dredged material mound
M
= subscript for total capped surface
