In this situation the gradient at each point along the river is sufficient to discharge the water and load but there is little excess energy available for further erosion.

Erosion is greatest on the outer bank, and with deposition on the inner bank, the neck of the meander becomes progressively narrower.As the river enters its middle course it starts to meander, the channel becomes asymmetrical on the river bends by mainly smooth and symmetrical on the straight stretches. In July, the UN activated a disaster management team to coordinate the activities of the various UN agencies. Groundwater levels were also much higher than normal – so there was little infiltration or percolation capacity.

In general, the long profile is smoothly concave, with the gradient being steeper in the upper course and becoming progressively gentler towards the mouth.Our "secret sauce" is a learning algorithm that delivers information to your brain in a way that optimizes its ability to retain that information. Rapids are found where there is a sudden increase in the slope of the channel or where the river flows over a series of gently dipping harder banks of rocks.
