Dam on the Wadi Samail (Sultanate of Oman)
Study of the staircase spillway
Client: Ministry of Water Resources of the Sultanate of Oman - Scale: 1/70
Context 
General view of scale model from downstream side
ARTELIA was contacted with the aim of protecting the inhabited areas of Wadi Samail against flash floods.
Construction of 4 dams and raising of the existing Al Kawd dam are planned.
Aim of model
Study energy dissipation on the stepped section to optimise the dimensional design of the stilling basin and resection the downstream wadi bed.
Description of scale model
- Unconfined flood spillway
- Stepped downstream face
- Structure height: 56 m
- Spillway width: 300 m
- Length of 500 metres downstream
- Maximum probable flood (MPF): 11,675 m3/s
