The current study investigates the impact of burrowing activities by crab species in the tidal flats of the Yellow River Delta in China on the hydraulic resistance characteristics of water flow,particularly the regula...
Flash floods are one of the most dangerous hydrometeorological events in the world.The current study investigates flash floods on the northern Black Sea Coast.The data about stochastic and relatively stable factors of...
In the context of transboundary rivers,which constitute intricate fluvial ecosystems,the persistent threat of heavy metals(HMs)contamination poses significant risks to ecosystem health.In this study,ecotoxico-logical ...
