Hydraulic Engineering and Dams

Arch-gravity concrete dam for water retention to supply agriculture watering, irrigating a total of 44 ha. Crown accessible to pedestrian traffic. Saquinho dam characteristics:
. Maximum height above foundations of 33,9 m and crown with total length of 87,6 m;
. Bleeder sized for a maximum flow of 312,0 m3/s, consisting of a single free discharger (type Creager) by the discharge channel on the badges below the dam, ending a ski jumping hill;
. Bottom discharge (Ø500 mm) inserted in the dam body and sized for a maximum flow of 1,8 m3/s;
. Water supply for irrigation (Ø300 mm) in the upstream face of the dam.
The irrigation water system uses a main conduit FFD cast iron (Ø125 mm), pumped from a station to be built in the Tabugal agricultural area, and 2 valves in high density polyethylene (Ø110 mm), one for each bank of the river for the reservoirs to be built in Chã do Monte (500 m3) and Ribeirão Areia (250 m3).
