Le terme Renaturation recouvre la revitalisation des cours d’eau et des rives de lacs, l’espace réservé aux eaux et la réduction des impacts négatifs de l’utilisation de l’énergie hydraulique (migration piscicole, les éclusées et le charriage).
La «plateforme Revitalisation» et la «plateforme Assainissement Force Hydraulique» sont une partie de l’Agenda 21 pour l’eau. Ces deux plateformes gèrent conjointement le site plattform-renaturierung.ch et soutiennent l’exécustion de la législation.
Le site Web sert à l’échange d’informations, d’expériences et de connaissances. Il s’adresse aux experts travaillant sur des mesures de renaturation des cours d’eau.

Sediments as a dynamic natural resource – from catchment to open sea
Sediments found in upland streams, industrialised waterways, busy coastal zones and offshore waters are characterized by a wide variety of sediment properties present in dynamic and less dynamic areas. These areas are inherently interlinked as sediment is transported from catchment to the open sea. The natural flow of sediment from mountainous regions to the ocean is strongly impacted by anthropogenic activities along this journey in terms of both the quantity that is transported and the quality of transporting waters. Sediment distribution is not only impacted by direct human influence but also indirectly as a result of changing weather and climate patterns. A change in sediment dynamics leading to sediment starvation or sediment accumulation is often the concern of river basin and coastal managers who constantly need to adapt to these environmental variations. Historical or emerging contaminants may also hinder the management of these areas.
At the SedNet 2019 conference we invite abstracts for a series of sessions aiming to explore these challenges and proposed solutions. This includes how policies and plans are developed for the range of often interlinked issues experienced along the journey from upland areas to the deeper waters such as how sediment quality should be assessed, sediment as an ecosystem service and how excess sediment can be used beneficially. The challenges posed as a result of anthropogenic influences, resource exploitation and climate change shall also be explored as well as emerging problems being examined such as contaminants resulting from discharge of waste.
