The Journal of Hydraulic Research (JHR) publishes research papers in theoretical, experimental and computational hydraulics and fluid mechanics, relating to rivers, lakes, estuaries, coasts, constructed waterways, and some internal flows such as pipe flows. To reflect current trends in water research, articles that explore outcomes of interdisciplinary hydro-environment studies with a strong fluid mechanical component are especially welcome. Although preference is given to fundamental issues, papers focusing on important unconventional or emerging applications of broad interest are also appreciated.

 Overview

This issue contains an interesting and well written vision paper that addresses the numerical approaches currently used for modelling tidal flows and marine turbines and highlights future challenges in this field envisaged by the authors. The remaining papers provide novel contributions to turbulence, flow stability, flow-vegetation interaction, cavitation, sedimentation, hydraulic transients and geysering, transport of eggs of sturgeon species, and numerical computation.
