Dear researchers and friends
I need to Plant Water Available Content (PWAC) map for a watershed. How is it possible? How can I estimate or calculate it? Are there any models or methods?
I would like to know the methods of root depth and effective soil depth Calculation and mapping in a watershed.
Any solution would be welcome
You may refer to the following two papers.

2.Gardner, E.A., Shaw, R.J., Smith, G.D. and Coughlan, K.J. 1984. Plant available
water capacity : Concept, measurement, prediction. In “Properties and
Utilization of Cracking Clay Soils” (J.W. McGarity, E.H. Hoult and H.B. Co. eds.), Univ. of New England, Armidale, pp.164-175.
In addition to the papers cited, I would suggest also some more recent attempts for the estimation at catchment scale.

Dear Mohsen,
providing some physiographic characteristics of your catchment can help.
Size, geology, soil types, relief,etc...
I suppose taht you want to feed a model, what model?
