HydroClimate Extremes, Modeling, Space and Time

In recent decades, the frequency and magnitude of hydroclimate (precipitation, temperature, streamflow etc.) extremes are exhibiting increasing trends and across the global. They inflict destructive punches on the infrastructure, ecology and, consequently, on socio-economy of countries, besides taking many human lives. These impact all parts of the world severely. This is underscored by (i) The recent line of extreme flooding events over monsoonal India (Narmada, Brahmaputra, Chennai, Kerala, Uttarakhand etc.). And (ii) on the other side of the world ongoing two decade long unprecedented ‘millennial drought’ in the snow-fed and semi-arid Colorado River Basin in Western USA, which serves over 40 million people and irrigates roughly 5 million acres of land. Thus, leading the Colorado River to be designated, in 2022, America's most endangered river.
