A poster presenting the project. The poster reads:

Postdoc offer 2026 - National-scale modelling of lake warming and water-level dynamics under climate change

The project will combine in situ data (A), remote sensing (B), and modelling (C) to model the 1D lake thermal structure of at least 210 reservoirs (D), i.e., sites for which a proof of concept is available. The model outputs will then be analysed to assess reservoir responses to climate change and water level management practices at the national scale.Your future lunch view?
