Dokumentation der Sturmflutschäden in Großenbrode, Sütel und Süssau
No full textDie schwere Sturmflut vom 20.10.2023 hat entlang der Schleswig-Holsteinischen Ostseeküste und speziell in den Gemeinden Großenbrode, Neukirchen (Ortsteil Sütel) und Heringsdorf (Ortsteil Süssau) sehr große Schäden an den Küstenschutzanlagen (Vorstrand, Dünen, Deckwerke, Wellenbrecher), Steilküstenbereichen und wasserseitigen Infrastrukturanlagen (Yachthafen, Promenade) verursacht. Dieser Beitrag dokumentiert auszugsweise diese sturmflutbedingten Schäden in Großenbrode, Sütel und Süssau, benennt exemplarisch schadensursächlich anzunehmende Einwirkungen und gibt Hinweise und Empfehlungen, die ggf. auch auf andere Küstenabschnitte übertragen werden können

No full textHydrological drought management in Spain
No full textIn Spain there is a long tradition organizing water distribution. To this purpose, water plans incorporate resource allocations, aimed at meeting specific water demands from specific resources. However, the variability of the Mediterranean climate causes droughts that lead to problems of water scarcity. To deal with them, special drought risk management plans are prepared. These plans incorporate a diagnostic system and a package of management measures that are activated or deactivated as the situation evolves, and an institutional organization by river basins capable of ensuring their effectiveness
Standing on a roller-coaster: the challenge of source water quality management in eutrophic reservoirs under recurrent drought conditions
No full textStructural water deficit is common to all Mediterranean regions. Demand concentrates in summer under dry-arid conditions, while precipitation mainly occurs in winter. Water availability also exhibits large interannual fluctuations. In the Guadalquivir River Basin in Southern Spain, for example, annual availability ranges from 400 to more than 20000 Mm3/yr, while yearly water demand remains stable at 3500 Mm3/yr. In such a context of extreme hydrological variability, man-made reservoirs used for drinking water supply and/or irrigation, are strategic infrastructures
Reframing water management from the lake's perspective: Lessons learnt on Lake Garda
No full textLakes break the continuity of catchments, often decoupling upstream and downstream fluxes in terms of water quantity and quality. They host strong interactions between physical, geochemical, and ecological processes and human activities, often concealed by relatively long residence times. Hence, lakes constitute a formidable challenge for the sustainable management of water resources but also a fertile ground for high-impact engineering research and innovation. In this article, we present an overview of the work of the newly established Physical Limnology Laboratory of the University of Trento, focusing on the lessons learned from our research on Lake Garda
