To study the fish behavioral response to up- and downstream passage structures, live-fish tests are conducted in large flumes various laboratories around world. The use of multiple fisheye cameras cover full width length a flume, low color contrast between flume bottom non-uniform illumination leading shadows, air bubbles wrongly identified as well being partially hidden behind each other main ...

Abstract Hyporheic exchange (HE) contributes to the biogeochemical turnover of macro- and micro-pollutants in rivers. However, spatiotemporal complexity variability HE hinder understanding its role overall functioning riverine ecosystems. The present study focuses on investigating bacterial diversity sediment morphology using a multi-flume experiment. A fully coupled surface–subsurface numerica...
