“…Hydrological disciplines in which tipping points have been identified include surface runoff (Dijkstra et al, 2019;Dunne and Black, 1970a;Horton, 1945), groundwater (Bailey, 2011;Figura et al, 2011), hydrometeorology (Buitink et al, 2020;Denissen et al, 2020;Krishnamurthy R et al, 2020), ecohydrology (Hirota et al, 2011;Mayor et al, 2019), and water quality (Dakos et al, 2019;Dijkstra et al, 2019). Moreover, these tipping points manifest themselves in all places: from arctic (Devoie et al, 2019;Rosier et al, 2021) to temperate climates (Kupec et al, 2021;van der Velde et al, 2021), from wet 10 (Loverde- Oliveira et al, 2009;Verbesselt et al, 2016) to arid regions (Bailey, 2011;Bernardino et al, 2020), and from hydrological source (Marty, 2008) to sink (Kirwan and Megonigal, 2013).…”
