The extensive food plain with level to gentle slopes (2^o to 5^o) and very low channel gradient makes the river so sluggish that it becomes a tangled network of interconnected diverging and converging shallow channels. Such a flood plain is said to be

A braided channel is characterized by a network of interconnected channels that repeatedly divide (diverge) and rejoin (converge) around sediment bars or islands. This occurs when the sediment load is too high for the channel to transport, causing deposition that forces the flow to split. The description matches perfectly: extensive floodplain, gentle slopes (2-5 degrees), very low channel gradient, sluggish flow, and a tangled network of shallow diverging and converging channels.
