Floods and droughts: two sides of the same hydrological coin

Floods and droughts: two sides of the same hydrological coin

This is not (only) a flood. Inspired by Magritte’s painting: ‘Ceci n’est pas une pipe’ After an alarming dry winter, the European continent has been enduring weeks of a record-breaking heatwave across the southern regions, while coping with scattered, intense precipitation and flash floods. In Zaragoza (Spain), recent flash floods swiftly transformed the previously dry landscape into raging rivers ...[Read More]

Urban streams can provide water sources for climate change mitigation

A schema of the ProBach methodology.

With advancing climate change, mitigation measures are necessary to fight urban heat islands. Reactivating urban streams as blue-green infrastructures can contribute to this mitigation, and serve as an invaluable water resource.  Urban streams – banned to the underground In urban areas, hydrological conditions have been modified, impacted or completely changed for centuries.  Rivers and stre ...[Read More]

Behind every robust result is a robust method: Perspectives from a hydrological case study

Behind every robust result is a robust method: Perspectives from a hydrological case study

Scientific studies and mathematical models are increasingly used to guide the management and development of society. But while science and modelling can indeed provide a robust basis for decision making, we must be mindful of two related considerations. First, science is based not on trust but on skepticism, meticulous technique and careful verification. Second, science is not made of absolute tru ...[Read More]

Hydrological modelling in times of flooding

Hydrological modelling in times of flooding

What a strange summer! Depending on where you live, you might currently be suffering from heat. In Switzerland, we are suffering from an exceptionally rainy and stormy weather situation, with high to very high flood danger issued for many major rivers and lakes (see warning map above, taken from the Federal Office for the Environment FOEN on Wednesday 14 July). For certain rivers, controlled flood ...[Read More]
