dam

Many dams and spillways have large gates or valves to control flow.

Gravity dams are designed to be heavy enough that hydrostatic forces can’t slide them backwards or turn them over.

The Hoover Dam was built in a narrow canyon and needed massive diversion tunnels through the rock on either side.

Dams come in all shapes and sizes, but contrary to what you might think, the most dangerous dams are often the smallest.

Low head dams almost always have subcritical flow upstream.

Some dams might have a convenient geological layer into which a cutoff can be terminated, creating an impenetrable envelope to keep seepage out.

A weir is a small dam built across a river to control the upstream water level.

This is why many dams are constructed in phases.

They build and maintain roads, bridges, and dams on reservations.

Large-scale storage of water is mostly restricted to surface water reservoirs formed by dams that are expensive and environmentally unfriendly to construct.

While the battle rages, your blood vessels let fluid stream into the battlefield like a dam opening up towards a valley.

These work fine for small- and medium-sized projects, but what if we need to layout something big like a road, bridge, dam, or pipeline?
