ABSTRACT

This study examined the flood in Kaduna using the meteorological characteristics of Kaduna River watershed by Regression analysis with Statistical Package for Social Science (SPSS 20). The hydrological parameters used for the study include; precipitation, relative humidity and temperature records from 2010 to 2014 collected from Nigeria Meteorological Agency (NIMET). The results obtained from the flood model created using the meteorological records showed that 2011 has the highest values for discharge and river stage as 22553.1758mm³/s and 3.7.5353m respectively hence justifying the devastated flood during that period. From the results, correlation coefficient, R=0.497 and coefficient of determination, R² = 0.247 for the model. The significant F of the discharge is 0.739 which is higher than 0.5 acceptable limits. These show the significance of the parameters used for creating the models were ok. The model can be adopted for flood studies in the basin for future studies.
