The Middle Course Features
Your river's personality completely shifts in the middle course - it slows down and starts carving elegant curves across the landscape. The main job here is transportation, moving sediment downstream rather than just cutting downwards like in the upper course.
Meanders are the star feature of this section. These S-shaped bends form because the river erodes from side to side rather than straight down. The land here is moderately sloping, giving the river room to wiggle about.
Two key features appear on every meander bend. The river beach forms on the inside bend where slow-moving water drops larger pebbles and sediment. Meanwhile, the river cliff develops on the outside bend where faster water undercuts the bank through erosion.
Quick Tip: Remember that fast water erodes (outside bend = river cliff) whilst slow water deposits (inside bend = river beach). This pattern never changes!
The flatter valley floor makes this area perfect for human activities. Farming thrives here because the soil is fertile and the land is easier to work. Towns and villages pop up along these stretches, and recreational activities like fishing and camping become popular.
