Regional Variation in Gravel Riverbed Mobility, Controlled by Hydrologic Regime and Sediment Supply
Sign Up to like & getrecommendations! Published in 2018 at "Geophysical Research Letters"
DOI: 10.1002/2017gl076747
Abstract: The frequency and intensity of riverbed mobility are of paramount importance to the inhabitants of river ecosystems as well as to the evolution of bed surface structure. Because sediment supply varies by orders of magnitude… read more here.

DOI: 10.1002/ird.2247
Abstract: On irrigated lands, drainpipe performance is often below standard due to clogging, siltation and root growth inside the pipe. To tackle these problems, an innovative pipe–envelope concept was tested on a 50 ha pilot area in… read more here.

DOI: 10.1007/s12224-020-09364-6
Abstract: River gravel-bar habitats are highly endangered. They are still well-preserved in the Caucasus, but developing conservation strategies is burdened by the lack of data from this region. We studied vegetation and habitat types on gravel… read more here.
