Abstract :

:– In northern India most of the rivers comprise alluvial deposits. During the monsoon the river banks are eroded and changed the river bank. Use of permeable structures is a cost effective alternative for the bank protection works. A dampening action on velocity of flow is achieved by permeable structures. In case of sediment laden rivers, permeable structures help to induce siltation along the bank. The sediment transport capacity of a flow is majorly depend on velocity. Therefore, the dampening of velocity results in deposition of sediment. In this present study, the effect of blocking of flow on various flow parameters such as velocity, discharge, sediment transport capacity, depth etc. is investigated with the help of experiments. Experiments were conducted in a 10 meter long, 0.30 meter wide and 0.45 meter deep tilting flume with the acrylic models having different blockage such as 10%, 20%, 30%, 40% and solid spur model. The results are analyzed and compared with the existing and field conditions. In this present study, from the result it was concluded that velocity get dampened and due to dampening sedimentation could start. The optimum permeability should be provided about 40%.
