Special Issue Information

Dear Colleagues,

Numerous hydraulic structures are built to manage water resources that play a crucial role in sustainable development and in strengthening the resilience of environmental, economic, and social systems. The improvement of fundamental knowledge and technologies on design, construction, operation and disaster management is key for the sustainable development of hydraulic engineering. Furthermore, efforts to ensure sustainability in hydraulic engineering should include consideration of the application of information technology, including BIM (Building Information Modelling), MIS (Management Information System) et al.

This Special Issue is devoted to the research of sustainable solutions for hydraulic engineering during the whole lifecycle. The Special Issue aims to bring together recent advances in all aspects of sustainable design, construction, operation and maintenance of hydraulic engineering (e.g., sustainable construction materials for hydraulic structures, recent progress in sustainable reliability-based design method of hydraulic infrastructure, advances in risk analysis for hydraulic structures under extreme conditions, etc.) that will potentially contribute to sustainable solutions for hydraulic engineering. In addition to topics related to engineered systems, topics related to environmental and economic issues in hydraulic engineering are also welcome.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Sustainable construction materials for hydraulic engineering;
  • Advances in design method of hydraulic engineering;
  • Environmentally friendly and lean construction technologies for hydraulic engineering;
  • Sustainable and intelligent technologies in operation and maintenance of hydraulic engineering;
  • Risk analysis and disaster management for hydraulic structures under extreme conditions;
  • Security assurance and protection technologies for hydraulic structures under extreme conditions;
  • Other recent progress in fundamental knowledge of hydraulic engineering

We look forward to receiving your contributions.

Curved channels are one of the most fundamental units of natural or artificial channels, in which there are different kinds of obstacles; these include vegetation patches, bridge piles, electrical tower foundations, etc., which are all present over a channel bend, and can significantly alter the hydrodynamic characteristics of a channel when compared to a bare bed. In this study, laboratory experiments and numerical simulations were combined to investigate the effect of a circular cylinder on the flow characteristics of a 180-degree U-shaped curved channel. Experimental data, including on water depth and three-dimensional velocity, which was obtained by utilizing acoustic Doppler velocimetry (ADV), were used to calibrate and verify the simulation results of the Reynolds-Averaged Navier–Stokes (RANS) model in the FLOW-3D software. Numerical results show that a larger cylinder diameter leads to an overall greater depth-averaged velocity at the section, a greater shear stress acting on the banks on which the cylinder is placed, and a greater increase in the depth-averaged velocity along the concave bank compared to that along the convex bank. When the diameter of the cylinder placed at the 90° section increases, two weaker circulations with the same direction are found near the water surface; for the submerged one, the two weaker circulations appear at the further downstream section, unlike the emergent one. The degree of variation degree in the shear stress acting on the banks is larger than that of the flowrate. As the flowrate increases or the radius of curvature decreases, the secondary flow intensity correspondingly elevates. However, the curvature radius of the curved channel plays a more important role in the secondary flow intensity than the flowrate does. For both the emergent and submergent cylinders, the large cylinder produces a greater secondary flow strength, but the emergent one has a greater secondary flow strength than the submergent one. In summary, the present study provides valuable knowledge on the hydrodynamics of flow around emergent and submergent structures over a curved channel, which could improve the future design of these structures.

The creep associated with unloading surrounding rock during the excavation of deep tunnels seriously affects the stability of the tunnel, and a high seepage pressure will aggravate the strength attenuation and structural deterioration of the surrounding rock. Based on the background of the excavation-induced unloading of the surrounding rock of a deeply buried granite tunnel with high seepage pressure, in this paper we carry out a triaxial unloading seepage creep test that considers the effects of both excavation disturbance and seepage pressure. We also analyze the mechanism of unloading and seepage pressure leading to sample failure and construct a fractional creep damage constitutive model that considers the unloading effect. The results include the following findings, firstly, seepage pressure will affect the creep deformation of rock for a long time, and the circumferential expansion of the granite creep process is more obvious than the axial expansion. Secondly, a high seepage pressure will reduce the rock bearing capacity. Under 0, 2 and 4 MPa seepage pressures, the long-term strength of the samples are 193.7 MPa, 177.5 MPa and 162.1 MPa, respectively. Thirdly, the rock damage factor increases with increasing seepage pressure, time and deviatoric stress. Finally, the rationality of a fractional-order model that considers the effect of unloading and seepage is verified by the test data. These research results may provide some reference for the stability analysis of surrounding rock during excavation in environments under high-stress and high-seepage-pressure. Full article
