Special Issue "Physical Modelling in Hydraulics Engineering"
Deadline for manuscript submissions: 30 May 2020.
Interests: coastal hydraulics; fluvial hydraulics; port operability
Interests: urban hydrology; runoff and wash-off processes; sewer sediments; combined sewer overflows; imaging techniques
In recent years, the application of physical modeling in hydraulic engineering has experienced an increasing progress due to several factors, such as (i) the development of new large-scale models, which allows analyzing and simulating different processes in controlled environments under close-to-reality conditions, (ii) the development of new measurement techniques, such as imaging techniques or the application of low-cost technologies, and (iii) a change in the vision of hydraulic engineering that is now more closely connected with other areas of knowledge linked to water quality, ecosystemic services or the social perception of traditional engineering works. These factors, together with other societal challenges such as climate change, population growth or the digitalization of the water sector, have led to a paradigm shift in the development of physical models in the field of hydraulic engineering.
This Special Issue aims to cover the main relevant physical modeling approaches related with hydraulics engineering, including hydraulic structures, fluvial, coastal, transition zones, urban, and ecosystems. All contributions are welcomed, including innovative solutions for common aspects in nature and infrastructures, coming from both basic and applied research. Topics regarding novel instrumentation and application of usual devices to new developments, real case studies, and adaptation to climate change scenarios are especially welcomed. Other topics covered in the Special Issue are nature-based solutions both for environment to urban locations, and studies with comparison with numerical modeling for its calibration, as increasing field of interest. Tentative papers are intended to deeply describe the materials and methods used in the physical modeling, scale effects, and accuracy of the measurements to validate the results.
We await your contributions for this Special Issue of Water, with an attractive impact factor and dissemination worldwide in the scientific community.

Title: Energy Dissipation of Rectangular Free Falling Jets with Downstream Supercritical Flow Conditions

Abstract: In recent years, several studies have shown that the current capacity of many spillways may be inadequate, increasing the possibility of overtopping during extreme events. In this situation, new loading scenarios are created in the dams, raising questions about the phenomena of energy dissipation and erosion control at the dam toe. To date, information regarding the behaviour of air-water flows in the plunge pool of free-falling jets is scarce. This study experimentally analyses the flow properties in free falling jet and the supercritical flow after the jet impact. Experiments have been obtained in a 1 m wide experimental device, with a sharp crested weir with the weir crest located at elevation of 2.20 m from the bottom of the plunge pool. Air-water flow properties have been measured in different sections from the weir crest to impact point in the plunge pool. Besides this, the supercritical flow downstream the stagnation point has been also analysed. In the measurements, an intrusive double-tip phase detection probe and a back-flushing Pitot tube have been employed. Several hydrodynamic variables are analysed such as: air concentration (void fraction), bubble frequency, jet velocity, jet thickness and the variation of the solid inner jet core.
Title: Physical modeling study of river discharges and the effects of rotation

Abstract: Pollutants from industrial plants and sewage outfalls are often carried by rivers into large-scale water bodies, and improper control of the transport processes may jeopardize the ecology and environment of the receiving water bodies. Therefore, it is important to better understand the mixing and transport properties of the discharges. The spreading characteristics of small-scale discharges are typically governed by inertia and buoyancy, but the effects of earth’s rotation should not be ignored for large-scale discharges, such as river plumes. To date, information about the effects of rotation on the mixing and transport properties of river discharges is scarce. This study reports physical model experiments of discharges in a rotating system. The experiments were conducted in a rectangular basin, which was hosted on a purposely built rotating table. Various experimental parameters are examined, such as nozzle diameter, initial velocity of discharge, and speed of rotation. The transient spreading processes are recorded, data are extracted using image processing techniques, and mixing and transport characteristics of the discharges are analyzed both qualitatively and quantitatively. The experiments clearly show the effects of source discharge conditions and rotation on the discharges, and provide a comprehensive dataset for development and validation of numerical models.
