This is a very detailed model of the Hoover Dam. I reconstructed this from circa 1930 Hoover Dam and Appurtenat Works drawing I got from the internet. This model shows how the Hoover Dam Intake towers, overflows spillway, tunnels and bypass system works. This is a "must download" for all civil engineers or anyone who is curious on how the Hoover Dam woks.
I traced the contours from a topography I got from a wikipedia. Here's the link: http://upload.wikimedia.org/wikipedia/en/a/a6/Hoover-dam-contour-map.jpg. I only traced every 100' major contour form the topo map. Here's a link that shows the Appurtanant works: http://upload.wikimedia.org/wikipedia/en/b/be/Hoover-summary-map.jpg. This showed me how to draw the tunnels and intake towers. Since it showed both the plan and profile view it was easy to translate this into 3D. #Civil_Engineering #Colorado_River #Dam #Hoover #Hydroelectric
