    Hello Niazi -

    We usually get the biophysical table values from a literature search. Ideally, you'd find studies that have been done in your area, or nearby, that provide values for root depth and Kc for the types of land cover you are working with. But if no studies have been done nearby (or in a similar ecosystem/climate/etc) you can use more global values. The Data Sources section of the User Guide provides some ideas for global sources, or how to calculate them.
