The heavy rainfall event in August 2002 in Saxony/Germany caused the break of a flood retaining basin in a valley of the Erzgebirge Mountains. The rainfall event with ists hyrologic characteristics and dam break event were analysed and an outflow hydrograph was determing. The propagation of the dam break flood wave in the valleyas of the Briesnitz and Müglitz Rivers has been simulated. Calculated values were compared with some observed data.

Reservoirs and dams are often situated in the mountains upstream of cities and towns. This implies a theoretical but difficult to evaluate hazard potential for downstream communities. This paper reflects experiences of the related safety analysis practice including the steps from the breach estimation towards the drawing of special hazard maps.

Im Jahre 1954 verkündete Indiens erster Premierminister Jawaharlal Nehru, dass Staudämme die “Tempel des modernen Indiens” seien. Ausgehend von der These, dass dieser Aussage eine „developmental imagination“ zugrunde liegt, die bis heute ein auffälliges Merkmal vieler Diskurse zu Großprojekten in Indien ist, und dass die Medien eine wichtige Rolle darin spielen, diese Diskurse zu zeichnen, betrachtet die Dissertation die Frage, wie große Wasserinfrastrukturprojekte in der indischen Medienlandschaft dargestellt werden. Um diese Frage zu beantworten, wird in der Dissertation eine Medienanalyse durchgeführt, bei welcher die Berichterstattung zum Indischen River Linking Projekt (NRLP) und zu zwei Vorhaben, die im Rahmen des NRLP stattfinden (Ken-Betwa und Polavaram), im Fokus stehen. Das 168-Milliarden Dollar teure NRLP Projekt ist das weltweit größte sich im Bau befindliche Wasserprojekt und sieht den Bau vieler Staudämme und Verbindungskanäle vor. Kontrovers debattiert wird das NRLP insbesondere in Bezug auf die hohen ökologischen und sozialen Kosten: Nach einer historischen Einbettung des Themas wird die Medienanalyse anhand einer Auswahl an Zeitungs- und Zeitschriftenartikeln aus dem Zeitraum 2000 bis 2016 durchgeführt. Darüber hinaus beinhaltet die Arbeit ein Kapitel, welches sich auf Feldforschung im Polavaram Staudammgebiet bezieht, um Perspektiven, die ansonsten in Mediendiskursen häufig marginalisiert werden, aufzuzeigen; die der von Umsiedelung betroffenen Communities. Die Dissertation zeigt das Kontinuum der „developmental imaginations“ in Indiens Diskursen zu großen Infrastrukturprojekten auf, weist auf die Machthierarchien hin, die ausschlaggebend dafür sind, wem die Möglichkeit zukommt sich überhaupt an Diskursen zu beteiligen, und hebt politische Narrative hervor, die in dem Kontext eine starke Verbindung zu „Nationbuilding“ oder „Statebuilding“ Diskursen aufweisen. / In 1954 India’s first Prime Minister Jawaharlal Nehru proclaimed dams to be the “temples of modern India”. Based on the theses that this “developmental imagination” so visible in Nehru’s statement continues to be a prominent feature in discourses on large scale infrastructure projects in India until today, and that the media plays an important role in shaping these public discourses, the dissertation considers the question of how large scale water infrastructure schemes are covered within the Indian media landscape. To answer that question, a media analysis is conducted which focuses on the reporting on the Indian National River Linking Project (NRLP) and on two schemes being implemented under the NRLP: The Ken-Betwa and the Polavaram Dam Projects. The 168-billion-dollar NRLP project is the world’s largest water project in the making and includes the construction of several dams. It is designed to connect the majority of Indian rivers to a gigantic water grid. It is controversially debated, especially with regard of ecological and social costs. After a historical embedding of the topic, the media analysis is conducted through a choice of magazines and newspapers in a time period from 2000 until 2016. Furthermore, the dissertation incorporates a chapter based on field work in the Polavaram Dam area in order to shed light on perspectives often marginalised in the media discourses: those of the affected communities. The dissertation reveals the continuum of developmental imaginations in the discourses on India’s large scale infrastructure projects until today, points out how power hierarchies are at work with regard to who is able to participate in the discourses and who is not, and highlights narratives closely linked to ideas of nation- or statebuilding that are used by politicians within the media discourses.
