Mature river: A river with a gradient that is less steep than those of youthful rivers and flows more slowly . A mature river is fed by many tributaries and has more discharge than a youthful river. Its channels erode wider rather than deeper.
What is the mature stage of a river?
Meanders (Mature stage): • Bends in the river. Deposition occurs on the inside (Convex) bend as the water is moving slowly here. Erosion occurs on the outside (Concave) bend as the water is moving faster e.g. Burrin.

What are the features of the middle course of a river?
The middle course has two main features – meanders and ox-bow lakes . These are both results of varying speeds and friction levels in the faster moving water, compared to the upper course.

Stage is the water level above some arbitrary point, usually with the zero height being near the river bed, in the river and is commonly measured in feet . For example, on a normal day when no rain has fallen for a while, a river might have a stage of 2 feet (baseflow conditions).

What are the characteristics of upper course of a river?
Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges . Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.
