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

The current issue of the Journal of Hydraulic Research includes ten contributions, eight Research Papers and two technical Notes, in diverse areas of hydraulic engineering. More specifically, the themes considered in the Research Papers are: sea level rise effects on the flow of a river; dam-break flow behavior over different obstacle configurations; aerated cavity rollers; multi-slot fishway optimization; incipient flow conditions of non-uniform sediments; behavior of abruptly expanding hydraulic jump; vortex ripple morphodynamics; and effects of vegetation on fish swimming behaviour. Furthermore, the corresponding themes in the Technical Notes are: pipeline protection against water hammer effects; and the onset condition of a steady hydraulic jump. Theoretical, experimental, computational and machine learning tools are employed by the authors to advance the current state-of-knowledge on the above-mentioned subjects which are of interest to both researchers and practitioners.
