| Abstract | Keeping in view the agricultural based economy of Pakistan, prevention of siltation in irrigation systems is considerably significant. Siltation is a main cause of endangering the storage capacity of the barrage and one contributing factor in the water scarcity in concerned command areas of canals. The present study is aimed to assess the silt exclusion efficiency of the right undersluice’s silt excluder tunnels of Taunsa Barrage and its effectiveness in bypassing sediments downstream of the barrage by undistorted physical scale modeling based on the Froude number similarity law. The model sediments were selected on the basis of the same ratio of the particle fall velocity to shear velocity for both the model and prototype. A well-mixed ratio of model sediments consisting of three different grain sizes was used following the sediment characteristics in the prototype. The effectiveness of the undersluice silt excluder tunnels is expressed as the percentage of sediment passing downstream of the barrage through the silt excluder tunnels ranging from 11% to 62% at various selected designed operational scenarios. Similarly, the silt exclusion efficiency of the right undersluice tunnels was also found to be in the range of 65.2 % to 87.7 % based from the operational scenarios simulated in the physical model tests. |
