How do meanders form ks3
WebA meander forms due to both deposition and erosion on either side of the river channel. On the outside of the bend, there is more energy due to decreased friction, so the force of the water erodes and undercuts the bank on this side. However on the inside of the bend, where the river flow is slower, the material is deposited. WebMeanders are perpetuated through a process called helicoidal flow. As the surface flow of water hits the outer bank it corkscrews, flows along the river bed then deposits eroded …
