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 begins with a forum article featuring the notable contribution of Prof. Léopold Escande to hydraulics and IAHR, followed by papers that advance the current understanding of flow physics as well as the mathematical and experimental modelling of free surface and closed conduit flows.
