Understanding how water is stored and circulates on land at multiple temporal and spatial scales.
Reciprocal influences between climate, land hydrology and ecosystem functioning.
— Big questions —
– Where do plants get their water (and how do we tell)?
– How do/will ecohydrological systems interact with global environmental changes?
– Can we connect local insights to the big picture (and vice-versa)?
— Approaches —
Process-based modelling (including environmental tracers) and data-oriented approaches.
Sometimes merging the two above using data assimilation techniques.
