Population growth, urbanization and expansion of structural developments into flood prone areas of urban settlements of Nigeria are challenges requiring dynamic predictions of inundation areas; development of models for the propagation of flood waves on the floodplain; and the development of a rapid response and flood warning systems. Hydrologic and hydraulics modeling provide a veritable tool to investigate the spatial and temporary impact of the existing and future landuse changes in the floodplain on the water surface elevation, velocity, and flow patterns within the river reach. In this study the Saint Venant hydrodynamic equations were modified for floodplain development index and applied to investigate the spatial and temporary impact of the existing and future landuse changes on the water surface elevation, and flow patterns along the Kaduna River floodplain. Results obtained indicated that the Kaduna River floodplain is increasingly urbanized with a maximum encroachment rate of 85.31%, 68.47% and 67.54% respectively in Reach 2, Reach 3 and Reach 1, respectively over the period 1962 and 2009. The result also shows that the 5yr, 10yr, 25yr, 50yr, and 100yr floods when occur, the level of floodplain inundation could be as much as 82.53% to 94.48% of the width of the floodplain with Kigo extension, Sardauna Crescent, Kabala Doki, Living Faith Church area and parts of Ungwan most vulnerable.
