In this study, parameters of the Kostiakov, Horton, Modified Kostiakov, SCS, Philip and Smith models were estimated using the double-ring infiltrometer on two different slopes, viz. 4° and 23°; in morning and afternoon sessions to assess their usefulness in characterizing the infiltration process. Observations revealed that the average increment in temperature by 9°C increased the final and initial infiltration rates by 65% and 38% respectively. The combined effects of the 23° slope and higher temperature increased the infiltrated volume by 6.4 times. The comparative analysis showed Kostiakov as the most efficient model incorporating combined and individual effects of temperature and slope
