The study investigated changes in channel planforms of River Kaduna. Topographic maps were complimented with Mosaic of SPOT 5 satellite and Sentinel-2 images. Results showed that except for sinuosity index and channel length, channel width, braiding and channel migration exhibited considerable changes. These changes were evident in reduced velocity and stream energy, the type of sediment being transported, the silt materials being transported in suspension and the coarse sand and gravels being moved by lift and drag processes which are easily deposited, thus causing the channel to contract and braid. Channel migration occurred as gradual bend shifts leaving no evidence …
