Dear colleages

I'm looking for document which we can find theoretical concept of WEAP model and mathématic equations.

Thanks

See Chapter 7 (Calculation Algorithms) of the WEAP User Guide ( http://www.weap21.org/UserGuide ).

Also you can read some more theory and equations in the 2005 Water International paper "WEAP21--A Demand-, Priority-, and Preference-Driven Water Planning Model: Part 1, Model Characteristics," ( http://www.weap21.org/downloads/WEAPDSS.pdf )
