Geography - Modelling Erosion and Deposition
We explored erosion and deposition that occur around a meander on a river. We learned about how and why they occured then tried modelling this ourselves, using sand, water and stones. We created a river bed, including a meander, in our sand and lined this with stones. When we poured the water from the higher ground, this caused erosion on the outside of the meander, taking sand and stones with it. These were deposited further down on the inside of the next meander. Witnessing this in action enabled us to explain the process which we presented as a diagram in our Geography books. We also enjoyed spotting meanders and observing erosion and deposition on our Coombe Abbey trip and River Avon walk.
