Flooding along the river Will a warming climate affect floods? The prevailing sentiment is yes, but consistent signal in flood magnitudes has not been found. Blöschl et al. analyzed timing of floods Europe over past 50 years and found clear patterns changes that can be ascribed to effects (see Perspective by Slater Wilby). These variations include earlier spring snowmelt northeastern Europe, later winter around North Sea parts Mediterranean coast owing delayed storms, western caused soil...

The new scientific decade (2023-2032) of the International Association Hydrological Sciences (IAHS) aims at searching for sustainable solutions to undesired water conditions - may it be too little, much or polluted. Many current issues originate from global change, while problems must embrace local understanding and context. will explore crises by actionable knowledge within three themes: interactions, innovative cross-cutting methods. We capitalise on previous IAHS Scientific Decades...

The traditional model of in-person education is evolving, with distance learning becoming increasingly popular. Virtual Exchange (VE) enhances interest in by adding interactive elements. University Helsinki (UHEL) coordinates two EU ERASMUS+ VE projects: “Climate for Exchanges” (CLUVEX) and “Una Europa Exchanges Sustainability” (UnaVEx), running from 2023 to 2026. These projects address climate change sustainable development. Additionally, UHEL leads...

Abstract This study compares the flood regime of rivers in Ukraine and Austria over last decades. We used data from mountain lowland watersheds, where floods are caused by different processes. In order to identify possible shifts day occurrence annual maxima, we apply kernel density method time series two subperiods (1960–1987 1988–2015). use Mann Kendall test at a 5% significance level significant positive or negative trends maximum discharges.

Abstract. Nowadays, during the period of global climate change, scientists around world have noticed an increased incidence extreme natural disasters. The authors study suggested methods using change as a part genetic model maximal floods runoff. This makes possible introducing “climate changes” directly through stocks snow and precipitation spring flood runoff coefficients. object is basin Southern Bug – one largest rivers in Ukraine, which flows within two geographical zones forest-steppe...
