Keith Beven, born 23 July 1950, is a British hydrologist and Distinguished Professor Emeritus in the Lancaster Environment Centre at Lancaster University, where he has worked since 1985.[^1,2] He took a geography degree at Bristol in 1971 and a PhD on catchment hydrology at the University of East Anglia in 1975.[^2] Before Lancaster he worked at Leeds, at the Institute of Hydrology in Wallingford and at the University of Virginia.[^2] He was elected a Fellow of the Royal Society and a foreign member of the US National Academy of Engineering in 2017.[^1]

His work is on hydrological modelling and on the uncertainty of predictions from environmental models.[^1] With Mike Kirkby he originated the TOPMODEL concepts, and he devised the Generalised Likelihood Uncertainty Estimation (GLUE) method, which has since been applied in fields as far apart as flood inundation and tree death modelling.[^1] His books include Environmental Modelling: An Uncertain Future? (2009) and Rainfall-Runoff Modelling: The Primer.[^1]

The idea of "models of everywhere" is his; in full, models of everywhere, everything and at all times. He revisited it with [Gordon Blair](/people/gordon-blair/) and others in 2019.[^3] Blair's [Digital twins of the natural environment](/articles/blair-digital-twins-of-the-natural-environment/) links that idea to twins of places.[^3]
