pond evaparation

[yan Peng]

Dear all,

I want to simulate the hydrologic cycle between several ponds. Could anyone tell me the evaporation method swat used on ponds.

thanks

Pond, Wetland, and Reservoir evaporation rates are all set at 0.6*PET.
PET depends on which method you choose (Penmon-Montieth, Priestly-Taylor, or Hargreaves).
You can alter the 0.6 coefficient (pndevcoeff and wetevcoeff in the pnd table, evrsv in res table) if you want.
  (If you look at the tables and the values are zero, that really means "default" and the code will use 0.6).
