Out of a wide perspective, the study examines the development of flood control in the region of the river Gürbe in Switzerland from 1855 to 2010. It shows not only technical progresses, but also changes in philosophy. The author illustrates how concepts of flood control have been implemented, which expectations and hopes were connected with them, and what effects the activities of flood control had.

Die Luftfahrt machte während des Ersten Weltkriegs einen grossen Entwicklungsschritt. Nach Kriegsende standen Flugzeuge, Infrastruktur und ausgebildetes Personal zur Verfügung, was erstmals einen planmässigen und gewerblichen Luftverkehr ermöglichte. Dieser drehte sich in seinen Anfängen in erster Linie um die Beförderung von Luftpost. Die Autorin untersucht die Organisation, das Angebot, die Nachfrage und die Finanzierung des Schweizer Luftpostverkehrs - und erläutert, weshalb der Staat das unrentable Geschäft in hohem Masse unterstützte und somit überhaupt aufrechterhielt.
