Abstract
River bank erosion due to unstable banks and high flow variability is usually controlled using permeable and impermeable structures, which are not studied much yet and also cannot solely provide desired velocity reduction. These structures, along with a combination of porcupine screens followed by geobag (i.e., Hybrid layout), are investigated using CCHE3D model for emerged, transition, and submerged flow conditions with respect to porcupine height. An optimum hybrid layout showed velocity reductions of 35% in submerged and 70% in emerged conditions, which further increased with multiple porcupine screens.
