Sir, thank you for your series on HEC-HMS. I kindly request you to explain how we can obtain the parameters for different surface methods. This will be helpful for beginners in hydrological modeling. Thanks a lot for your effort in making hydrology education accessible to everyone.
It really depends on which parameter value you're asking about. For example, some values like Date (date of the burn) is historical data. However the Initial Rate and Maximum Rate (of infiltration) could be determined through empirical testing, and are also related to the soil type and the time since the last burn. I hope that helps.
