Klaus Kirchgässner was born in Mannheim on December 26, 1931, and died in Konstanz on July 9, 2011. He grew up in the small, lovely town of Waldshut, which is located along the Rhine at the extreme south of the Black Forest. With his friends he spoke with enthusiasm about this city, where he did swimming in the Rhine and in the Aare river and where he completed his high-school education (“Gymna...

The vairone Leuciscus souffia is a cyprinid fish that inhabits river systems in and around the Alps. The complete mitochondrial DNA control region (945 bp) was sequenced in 295 vairone from 22 populations in Central Europe. A total of 51 haplotypes were identified with a maximum pairwise distance between haplotypes of 5.6%. Phylogenetic analyses revealed two major clades in L. souffia, an 'Ital...

Realistic estimates of daily streamflow and water temperature are required for effective management of water resources (e.g. for electricity and drinking water production) and freshwater ecosystems. Although hydrological and process-based water temperature modelling approaches have been successfully applied to small catchments and short time periods, much less work has been done at large spatia...

Abstract. In this communication, we present the exposure of agricultural lands to flooding caused by extreme precipitation in western Europe from 12 15 July 2021. Overlaying flood inundation maps derived near-real-time RAdar-Produced Inundation Diary (RAPID) system on Coordination information environment (CORINE) Land Cover map estimate a 1920 km2 area affected flooding, with 64 % representing ...

A simple idealized model to describe the hydraulic resistance caused by vegetation is compared to results from flow experiments conducted in natural waterways. Two field case studies are considered: fixed-point flow measurements in a Green River (case 1) and vessel-borne flow measurements along a cross-section with floodplains in the river Rhine (case 2). Analysis of the two cases shows that th...

The 24 hour activity patterns of three non-native gobiids (round goby Neogobius melanostomus, Western tubenose goby Proterorhinus semilunaris and bighead goby Ponticola kessleri) were assessed over 46 consecutive months between 2011 and 2014 from their occurrence in the cooling water intake of a nuclear power plant on the River Rhine, Germany. In total, 117717 gobiids were identified and classi...

A retrospective epidemiological study in The Netherlands showed a statistical association between chlorination by-products in drinking water and cancer of the esophagus and stomach for males. A pilot-plant study with alternative disinfectants was carried out with stored water of the Rivers Rhine and Meuse. It was demonstrated that the increase of direct acting mutagens after treatment with chlo...
