Tests on Section of Overflow Dam and Degradation Below Dam of Naji Navigation Project |
| |
Abstract: | Flow capacity,pressure on dam face and energy disspation below dam was performed for sectionad design of overflow dam on the hydraulic sectional model with the scale of 1:30.From the tests, an optimum dam curve and energy obsorber is propose.As a result,flow condition of the energy disspating basin is improved,slucing capacity is reduced and investment saved. |
