Special Issue Information

Dear Colleagues,

Fluid mechanics plays an important role in various engineering applications to support the goal of sustainable energy and environment. Hydraulic engineers are at the forefront of scientific developments to deliver water to communities, and to protect our society from water-related disasters. The technical tasks faced by hydraulic engineers are formidable, and sustained research efforts are essential to provide some basic understanding of different phenomena, and to furnish predictors for design. In particular, the scientific challenges in environmental fluid flows are significant. The extreme levels of complexity are closely linked to the variety of water systems; the broad range of relevant time and length scales; the variability of river flows, from droughts to gigantic floods; the complexity of basic fluid mechanics with non-linear governing equations; flow instabilities; and interactions between water, solid and air phases, as well as with fauna and flora.

Environmental fluid mechanics encompasses the scientific studies broadly relating to natural fluid systems on our planet (i.e., air and water) affecting the environmental quality of life. Understanding transport and diffusion/dispersion processes in natural fluid flows, from the sub-millimetric scale to the planetary scale, serves as the impetus for the development of theoretical models, simulations and predictions, leading ultimately to sustainable environmental management. Altogether, the subject areas are diverse and may originate from a variety of scientific and engineering disciplines: civil, mechanical and environmental engineering; meteorology; hydrology; hydraulics; limnology; and oceanography.

Clearly, environmental fluid mechanics brings new challenges and solutions which are directly relevant to hydraulic engineering broadly. Therefore, this Special Issue focuses on environmental fluid mechanics from different regions of the world and different hydraulic structure layouts—firstly because further studies based on experimental and model designs that are more specifically directed at this specific issue are needed in order to fully understand flow interaction phenomena and the impact on the environment; secondly, because we also need new innovative solutions. In addition, we would like to refer to solutions that are close to Nature with low environmental impact.

We invite contributions from the latest laboratory, field, and/or numerical research studies on the available or innovative new solutions of structures and tools to evaluate the effectiveness of the solutions. Original research papers and critical reviews will be considered. All scales of application are accepted. You are all very welcome to contribute.

Hydrodynamic Characteristics of Strong, Unsteady Open-Channel Flow

by Keke Hu, Jian Hu, Tianwei Huang, Xiangwei Ye, Shu Jiang and Ying-Tien Lin

Abstract

Due to climate change, the intensity of extreme rainfall has been observed to increase with a shorter duration, causing flash floods (strong, unsteady flow) that lead to serious loss of life and economic damage all over the world. In this study, by repeating the same flume experiments twenty times over a bare bed or with a submerged vane installed, the hydrodynamic characteristics of a strong, unsteady open-channel flow were investigated. Acoustic Doppler velocimetry (ADV) was used to measure the instantaneous three-dimensional velocity, and the ensemble average method was then adopted to obtain the time-varying mean flow velocities. Reynolds decomposition was applied to disintegrate the instantaneous velocity to time-varying average velocity and fluctuating velocity. Turbulence characteristics such as turbulent intensity, turbulent bursting, and power spectral density (PSD) were analyzed against water depth variations. The results show that the loop pattern of the streamwise velocity against the water depth variations could significantly affect the turbulence characteristics of unsteady flow. Near the bed, the peaks of the turbulent intensity and the TKE lag behind the peak of the water depth. The PSD revealed that the turbulent energy increases at the rising and falling stages were due to the generation of small-scale turbulence vortices or eddies. As a submerged vane was present, the increase in the angle of attack caused the increase in the turbulent intensity and TKE, which means that the induced vortex became stronger and the wake region was larger. When the angle of attack was equal to

20 °

, the TKE abruptly enlarged in the falling stages, implying the breaking-up of the induced vortex. The PSD of the transverse fluctuation velocity showed multiple spikes at the high-frequency part, possibly denoting the shedding frequency from the induced vortex. Further downstream, behind the submerged vane, the peak frequencies of the PSD became imperceptible, likely because of the induced vortex decays or other factors such as the turbulence generated from the free surface or the channel bed mixing with the turbulence from the induced vortex.

The Impact of Spontaneous and Induced Restoration on the Hydromorphological Conditions and Macrophytes, Example of Flinta River

by Stanisław Zaborowski, Tomasz Kałuża and Szymon Jusik

Abstract

Highly modified riverbeds are not able to spontaneously reproduce natural processes. The restoration of natural river systems is an important challenge to modern river engineering. Various procedures and solutions, both technical and non-technical, are applied in this process. This involves looking for simple solutions that are close to nature and that interfere with river ecosystems to a minimal extent. One of these solutions is deflectors, which constitute a type of simplified spur. This study presents the results of the research on the transformations of hydromorphology and macrophytes on selected sections of the Flinta River, which represents the most common type of river in the Central European Lowlands (a small river with a sandy substrate). Two neighbouring sections of the watercourse were selected. The first one has not been subject to any regulatory measures for over 30 years and is undergoing spontaneous restoration, while the second one was significantly altered (straightened, cleared of hydrophytes, and desilted) ten years ago. Three deflectors were introduced in this section in the years 2017–2018. Research conducted on both sections enabled the determination of the possibility of initiating renaturalisation processes by way of implementing simple solutions in the form of low-cost wooden deflectors. It also provided the basis for the assessment of the impact the measures taken had on the hydromorphological status of the watercourse and on macrophytes. Based on the studies conducted, it was possible to determine the size, dynamic, and scope of the changes taking place in the river under various conditions of its transformation, including those resulting from anthropopressure.
