Journal of Hydraulic Research | Vol. 59. Issue 2, 2021

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.

Journal of Hydraulic Research | Vol. 59. Issue 2, 2021

 Overview

This issue makes fundamental contributions to a range of hydro-environmental engineering problems such as steady and unsteady open channels; stability of hyperconcentrated flows, slurries, and shallow shear flows in the presence of vegetation; water hammer; load rejection in pump-turbine systems; hydraulic roughness in mixed bedrock-alluvial meandering channels; turbulence and waves; and entrainment of density flows. These papers represent an excellent mix of theoretical, numerical, and experimental approaches.
