High-frequency velocimeters used for flow measurements during laboratory experiments allow the user to select range several operation parameters set up instrument optimal velocity measurement. The discrepancies between collected with different configurations can be significant, depending on flume bed configuration and boundary conditions. aim of this paper is quantify differences in profiles me...

In human-impacted coastal ecosystems, living shorelines are becoming a common restoration technique. However, we lack comprehensive understanding of the ecological and physical benefits, how they could inform management needs. To address this, studied effectiveness at broad spatial scale within Washington State boundaries Salish Sea, USA, with restored site ages spanning 1–11 years. We surveyed...

Zur Verbesserung des ökologischen Zustandes an Binnenwasserstraßen sind in den nächsten Jahren umfangreiche Uferumgestaltungen vorgesehen. Naturnahe Ufersicherungen unter Verwendung von Pflanzen sollen dort, wo es möglich ist, die bisherigen Steinschüttungen ersetzen, um wieder mehr Lebensräume für und Tiere sowie Strukturvielfalt zu schaffen. Mit diesen technisch-biologischen gibt Wasserstraße...
