Abstract Purpose This paper describes the efforts made by SedNet—the European Sediment Network—to generate attention for the inclusion of sediment in River Basin Management Plans (RBMPs) under the European Water Framework Directive (WFD). Materials and methods The SedNet response to key WFD implementation events is described using the “three-streams and windows-of-opportunities model” published by John Kingdon in 1995. Results and discussion SedNet was initially a response to the realization that the WFD—which came into force in 2000—largely neglected sediment. For SedNet, it was clear from the beginning that the WFD objectives can be achieved only if sediment is included in RBMPs. The SedNet efforts inspired the establishment of a sediment management concept for the Elbe river basin. That concept was used as a basis for the full inclusion of sediment in the second Elbe RBMP (2015–2021). SedNet experts are currently involved in the drafting of the WFD Common Implementation Strategy (CIS) sediment document which will be completed in 2021 and that will provide guidance about how to include sediment in RBMPs. Conclusions Since 2000, SedNet has persistently drawn attention to the need to include sediment in RBMPs. However, it was not until 2015 that the Elbe became the first European river basin to include sediment management fully in their RBMP. The 2021 WFD CIS sediment document and the focus on sediment in the Water Fitness Check in 2019 make it significantly more likely that the sediment will be included in the updates of WFD RBMPs in the near future.

AbstractThe morphology of rivers and deltas, like many features of the Earth’s physical geography, is today subject to dramatic and rapid changes due to human actions. Deprived of sediment from their basins and besieged by rising sea levels, many deltas are at risk of complete disappearance. Despite a rich historical scholarship on rivers, we know little about the history of these important geomorphological processes. This paper sheds light on the geomorphological history of rivers by investigating the case of the Po River basin and its delta during the twentieth century. By combining the insights of fluvial geomorphology and a historical methodology, the paper analyses three main drivers of geomorphic alterations in the catchment that had an impact on the delta: hydroelectricity, sand and gravel mining, and methane extraction. In each case, it focuses on how experts, policy-makers, and overseers understood and regulated (or not) these geomorphic alterations. During much of the twentieth century, engineers and hydrologists monitored geomorphic processes with increasing detail, while state and business actors practiced multiple forms of sediment management. For most of the twentieth century, however, experts did not acknowledge the scale and nature of human-induced geomorphic alteration. Sediment management, moreover, did not take into account sediment scarcity until late in the century, and remained exclusively motivated by local concerns. Through this particular case, this paper offers insights on the historical limits to environmental expertise and policy when facing long term and large-scale geomorphic processes, and encourages a more sustained incorporation of fluvial geomorphology into the history of water systems.
