| This study is concerned with the hydraulic experiments of Modi Khola Hydroelectric in Nepal. The experimental domain consists of the intake structure and the settling basin. The intake structure was made by the undistorted model with the scale of 1:20, the settling basin by the distorted model with the scale of 1:10(vertical) and 1:15(horizontal). Based on the movable bed model theory, the 'Anthracite'($
ho_s$ =1.48) is chosen as a model material. According to the model tests, the installation of the guide wall with proper height and the proper control of the flushing gate are required for the effective flushing in the intake structure. In the settling basin a more proper design of the inlet in order to constrain the turbulence flow is required for an efficient sedimentation and the installation of another flushing pipe near the maximum sedimental area is required. Since the trap efficiency is measured about 95%, it is concluded that the design of the settling basin is proper. |
