Description:

Roller compacted concrete (dam body) and earthfill (right abutment) dam for hydropower purposes, located in Manhaçu river (Brazil). The dam is 30 m high.

The spillway on the central dam body was designed for a 14 333 m3/s flow.

AQUALOGUS developed the detailed design for the rehabilitation, afeter the occurrence of a slope instability downstream of the right abutment, associated with internal erosion phenomena occurring 70 m to the right of the insertion of the dam body in the foundation.

Description:  

Existing gravity concrete dam, for water supply and irrigation purposes, located in Béchar (Algeria). The dam is 37 m high and stores 360 hm3. The existing spillway is uncontrolled with modified Creager profile and has insufficient capacity.

AQUALOGUS analyzed hydraulic and structural safety conditions and proposed measures to rehabilitate the dam, including increasing the capacity of the reservoir and constructing a complementary spillway.
