It is 40 years since the journal Hydrological Processes started. The editors have just published a top 40@40 here, and in a blast from the past, I'm delighted that Baker & Inverarity (2004), on fluorescence and water quality, has made the list: https://onlinelibrary.wiley.com/doi/10.1002/hyp.5597 (sadly behind a pay wall, but the pre-proof is available on ResearchGate). The research was a collaboration with the Environment Agency of England and Wales, using organic matter fluorescence as a indicator of water quality at a catchment scale. Only possible due to the support from Roger Inverarity at the EA. The full 40@40 is here: https://onlinelibrary.wiley.com/doi/10.1002/hyp.70695 #academia #hydrology #waterquality
