I have a problem with permanent wilting point WP. According to the formula WP = 0.40 * ((% CLAY * Bulk Density) / 100). My data shows that% CLAY = 5%, BulkDensity = 1.55. After converting, I have the result of 31mm per 1000mm of soil. To my knowledge it should be approx. 110 mm per 1000 mm of soil. Can I enter my own WP content data into the input.std file into the SWAT model?

Greetings
