Estimation of Infiltration Models’ Parameters Using Regression Analysis in Irrigation Fields of Northern Ghana

The quantification of soil infiltration is necessary for the estimation water accessibility in soils plant growth and development. Field tests runs were conducted on agricultural three irrigation sites Northern Ghana. field data fitted into Green Ampt, Kostiakov, Philip, Holtan, Soil Conservation Service Horton models determination unknown model parameters. Regression analysis at 95% confidence level using GraphPad Prism 8. Laboratory used fitting parameters determined calibrated models. k n Kostiakov Bontanga study site found to be = 28.0027 0.5902, 17.0294 0.4504 Golinga 23.0356 0.6339 Libga. For all models, coefficient ranged from 0.7612 0.9876 indicating strong relationships. Only Holtan gave different values sites. parameter GIa ic drawn hydrologic group same because vegetative cover surface conditions. observed have influenced models’ performance.
