River Tay - middle course
The middle course of the River Tay in Scotland begins as it leaves Loch Tay at Kenmore and ends just north of Perth. In this stage the river is carrying a large amount of sand, gravel and rocks. The river becomes wider and deeper and begins to meander. At a meander the bank at the outside of the bend is eroded by fast-flowing water. On the inside of the bend, the slow-moving water deposits silt and other material. This silt makes the soil of the river floodplain very fertile.
