If we talk about the basic definition of hydrology, then it is clear that it is a branch of environmental science which is related to the study of water bodies as a whole.

Ultimately, it would be nice to see followup forward modeling studies which attempt to use all potentially relevant variables, rather than the simplified model form we use (which is generally justified at treeline — but perhaps only to first order approximation, i.e. some of the details of changing hydrology and solar insolatino might still matter in these environments.).
