701-0034-20L | Integriertes Praktikum: Stoffkreisläufe in Seen | 3 KP | 3P | B. Wehrli | |
Kurzbeschreibung | Die Studierenden analysieren einen See als biogeochemisches Umweltsystem. 1. Einzugsgebiet: Wir bestimmen Stoffbilanzen über Zu- und Abflüsse sowie langfristige Inhaltsänderungen 2. Sediment-Archive: Wir schätzen Sedimentationsraten und rekonstruieren die Belastungsgeschichte. 3. Licht und Dunkel: Wir analysieren vertikale Wasser-Profile und schätzen Raten von Photosynthese und Respiration. | ||||
Lernziel | Die Studierenden können einen See als biogeochemisches Umweltsystem analysieren, d.h. • Sie beherrschen wichtige Methoden der chemischen Probenahme und Analytik für Fliessgewässer, Wassersäule und Sedimente. • Sie berechnen Stoff Frachten und bestimmen langfristige Inhaltsänderungen im See. • Sie können Sedimentationsraten abschätzen und aus Sedimentkernen die langfristige Belastungsgeschichte rekonstruieren. • Sie wenden einfache Modelle an, um die Prozessraten der Photosynthese und Respiration aus den täglichen und saisonalen Konzentrationsänderungen in der Wassersäule abzuleiten. | ||||
Inhalt | Viele Schweizer Seen haben seit den 1950er Jahre eine Phase der Überdüngung durchgemacht. Dank verbesserter Abwasserbehandlung, Phosphatverbot und Massnahmen in der Landwirtschaft hat sich die Wasserqualität in vielen Seen in den letzten Jahrzehnten stark verbessert. Die Zielsetzung einer mittleren Produktion und einer genügenden Sauerstoffversorgung in der Tiefe ist in vielen Fällen erreicht worden. Der Gemeindeverband am Sempachersee hat zusätzliche See-interne Massnahmen durchgeführt. In diesem Praktikum analysieren wir den aktuellen Zustand der Nährstoffbelastung aus Landwirtschaft und Abwasser, wir rekonstruieren langfristige Trends und wir ermitteln die Zusammenhänge zwischen den Stoffkreisläfen von Phosphor, Stickstoff, Sauerstoff und den Treibhausgasen von Kohlenstoff. | ||||

Kurzbeschreibung | This seminar focuses on the technical, economic, and political challenges of dealing with water allocation and pollution problems in large international river systems. It examines ways and means through which such challenges are addressed, and when and why international efforts in this respect succeed or fail. | ||||
Lernziel | Ability to (1) understand the causes and consequences of water scarcity and water pollution problems in large international river systems; (2) understand ways and means of addressing such water challenges; and (3) analyse when and why international efforts in this respect succeed or fail. | ||||
Inhalt | Based on lectures and discussion of scientific papers and reports, students acquire basic knowledge on contentious issues in managing international water resources, on the determinants of cooperation and conflict over international water issues, and on ways and means of mitigating conflict and promoting cooperation. Students will then, in small teams coached by the instructors, carry out research on a case of their choice (i.e. an international river basin where riparian countries are trying to find solutions to water allocation and/or water quality problems associated with a large dam project). They will write a brief paper and present their findings towards the end of the semester. | ||||
