Abstract: available low cost materials, the construction cost of the Bandalling is also low. These structures are placed at the erosion prone bank of the river Jamuna near the Bangabandhu Bridge East Guide Bund, Bhuapur, Tangail, Bangladesh. The bandalling structures are placed with an angle of the 45 degrees in the direction of water flow with the spacing at two times of the Bandalling length. It was observed that water flow is diverted towards the main channel and low flow velocity near the bank. Due to low flow velocity, sedimentation occurred near the river bank between the bandals indicates that bandalling can be used successfully as river bank erosion protection structures as like the convention groin/spur like structures.
