Structure shape versus channel shape<br />
Embankment height above thalweg = 6’<br />
Example of fit solutions:<br />
Low Profile Arch, 16’ wide, expensive due to shape and required thickness, Low<br />
hydraulic capacity.<br />
Concrete box 16’ wide or 24’ valley spanning, or similar thin structural bridge deck gives<br />
the most hydraulic capacity and may be comparable in cost to low profile arch.<br />
Better width<br />
for maximum<br />
