Comparison of River Bank Stabilization Methods using Computer Simulations (Case Study: Mashalak River)
Journal Title: Journal of River Engineering - Year 2014, Vol 2, Issue 4
Abstract
Protection and stabilization river bank operations along the river to prevent erosion, landslides coast, demolition of existing facilities and the riverside villages is very essential to the recovery of agricultural lands. In this paper, various methods of river bank stabilization such as Levee, Groin (Epi), Submerged Vane, biotechnical revetment, Riprap revetment and concrete revetment has been investigated. To achieve this end reach Mashalak River (approximate length of 2 kilometers) were considered because of urban and is important as the study area. Using software HEC-RAS, the model was simulated with the coastal protection structures and flow hydraulic conditions were compared with existing of river. Hydraulic parameters that were evaluated are mean flow velocity, shear stress and Chanel power. To investigate the best way of training among the existing methods, the parameter of the shear stress was chosen for comparison. Finally, the epi-levee option is introduced as the preferred method of hydraulically between the methods in the selected reach.
