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 last issue for 2024 includes a number of important contributions in diverse areas of hydraulic engineering that are of interest to the readership of the Journal of Hydraulic Research. The first paper proposes a revised two-phase analytical/numerical (CFD) method for modeling high-speed, self-aerated, free surface flows, such as those encountered in stepped chutes. The authors of the second contribution elaborate on the utility of the volumetric Particle Tracking Velocimetry method (PTV) in complex hydraulic engineering flows, which, together with the Shake-the-Box (STB) algorithm, is used to obtain instantaneous, three-dimensional velocity data and characterize the turbulent flow properties within a relatively large domain in the case of an undular hydraulic jump. In the third paper, a new multi-objective framework is developed for determining the creep function parameters of polymer pipes under intact and leaky scenarios. Such information is essential for analysing the behavior of transient flows and detecting anomalies in such pipe systems. In the next contribution, the authors demonstrate some of the modern control possibilities available in a water distribution network (WDN) by designing controllers for two challenging situations: a pumping system which suddenly loses power and safely filling an initially empty pipe using a pump. The penultimate paper, investigates the transient flow phenomena involving trapped air in pipelines by solving numerically the Euler–Euler two-phase compressible flow mathematical model. The surge tube example is used to demonstrate the validity of this model. In the last paper of this issue, the authors use a physical model to carry out a detailed experimental study that examines the effects of flood flows and woody debris on the pressures and forces exerted on an arch bridge. An improved understanding of these effects is very relevant considering the current concern about increased flood magnitude and frequency under climate change conditions.
