Alternated Gravel Mounts With Artificial Assembled Boulders Reinforcement Inside Channelized Rivers

Alternated gravel mounts are expected to be a simpler and more cost-efficient alternative traditional river restauration strategies. To improve their stability, two layers of assembled boulders placed like fallen dominoes facing downstream around the triangular shape each mount. Further along both sides channel. The ecological improvements quantified by definition refuge, i.e. anywhere inside flow where fishes might escape flooding’s force. In this paper, needs small sized considered (body length under 0.30 m). Point gauge electrical-magnetic current meter used measure elevation horizontal velocity components, respectively. channel slope is kept at 0.01, while four different discharges researched. collected results very promising: introduction important maintain model’s stability flatten water surface mounts’ successfully forces meander. Areas with slow flowing generated near bed channel’s sides. There, requirements for refuge met. As volume increases, straightens, particularly centre, but able areas still forming. Each mount generate suitable as large 40% its own, limiting factors such flood’s discharge or shallow conditions having little effect on performance.
