Document Summary

Gradient: refers to the position within the catchment. Catchment: depression in the earth where water runs off streams, rivers. River discharge: the amount of water flowing down a river / the volume of water flowing past a particular point at a particular time. As gradient , discharge volume of water the further you go down. Meandering channels / streams: form on inland plains, or low-gradient coastal plains, winding course, gentle gradients, variable flow rate water velocity not uniform water velocity on outside of bend is greater than on inside of bend. Inside bends: velcooity --> build-up of sediment depositional. Outside bends: velocity more erosion water flows faster: point bars. Braided channels: common in high country/mountains, shallow channels, carry lots of eroded sediment, channels shift position all the time. **meandering streams and braided channels = two main types of streams/channels in.
