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 excellent research contributions to a wide range of interesting and important hydro-environmental engineering problems including vegetated flows, bed roughness, flows beneath ice cover, porous media, water supply, pump-turbines, spillway hydraulics and air entrainment. In addition, there is a case study on seepage through earthen dams.
