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 includes eight research papers, three of them are dealing with various aspects of hydraulic structures, two more consider phenomena related to river flows and erosional processes, one is employing a non-invasive method, ultrasonic waves, for evaluating rheological properties of non-Newtonian slurries, another one formulates the problem of flow through vertical trash racks clogged by vegetation debris, and the last one simulates numerically and experimentally the movement of bubbles in river crossing pipelines. More specifically, the authors of these contributions recommend an inlet design for improving the hydraulic performance of vertical shaft spillways; investigate the response of compound channels to coupled flood discharge and base level drop; propose a nature-inspired cross-sectional shape of a conduit to better control the effects of hydraulic transients; discuss the utility of ADCP measurements for estimating the bed roughness of a river; and examine the impact of various sediment characteristics and their concentration on the abrasion of a Pelton turbine.
