Hydro-geography is the subject describing all water flows on and beneath the earth. Hydro-geography is part of physical geography; it is focussing on interactions among landscapes and water balance of a determined area.
The hydro-geography deals specifically with
- the water balance
- the spatial and temporal changes of water storage and
- the flow behavior with regard to the quantitative aspects, as well as the
- water quality in terms of qualitative aspects.
Of special interest is the human intervention in the water systems .
