Quite a general question...
I am referring to a scientific paper : http://www.springerlink.com/content/41p817v1584q1850/
I am trying to model water temperature over a year.
I have the initial value which is 30 for Tw (water temperature).
The author says that equation 1 should be easily integrated. Would I have to integrate all equations feeding into the equation?
Unfortunately the modeller for this paper has passed away and the remaining authors are unsure how he modelled for water temperature. Need a mathematician :)
For now I have made the input vatiables static assumptions over time.
