Sustainable Hydraulic Structures Planning, Design, and Analysis: New Planning and Design Applications

Dear Colleagues,

Dams, weirs, spillways, gates, and river regulation structures are important hydraulic structures. Dams store behind them flood waters, primarily for the benefit of people. Hydraulic structure sustainability is an important concern from a water engineering viewpoint, although increasingly they constitute an issue of effective public debate. Indeed, the failure or collapse of dams has high economic and social consequences. In terms of climate change scenarios, it is imperative to test the spillway, sluice gates and energy dissipation structures of the constructed dams. The changing climate raises serious concerns about water scarcity and energy production. For hydraulic structures, it is vital to develop sustainable rehabilitation projects and increase the discharge capacities of spillways or weirs when necessary, an issue which has become a major problem worldwide. In cases of insufficient spillway capacity, dam failures may occur. This is especially important in the presence of cascaded dams. It is possible that the spillway capacity will not be sufficient due to climate change. In recent years, issues involving these kinds of risk analysis have gained great importance. In order to increase discharge capacity, many studies have been carried out on labyrinth spillways and piano key weirs in recent years. Such spillways are also used as additional spillways in dams. Thus, the design of new dam types and the development and analysis of new spillway types have important roles to play in the sustainability of water resources engineering. As in all engineering structures, sustainability is also important in river regulation structures, and other hydraulic structures. Climate change-induced floods in rivers affect bridge safety. The fact is that flow is within the supercritical flow regime and the pressurized flow increases the scour around the bridge piers. Thus, conducting up-to-date studies on these issues will be beneficial for readers and application engineers. Sustainable hydraulic structure planning, design and analysis are needed to achieve the Sustainable Development Goals.

This Special Issue, entitled “Sustainable Hydraulic Structures Planning, Design, and Analysis: New Planning and Design Applications”, focuses on hydraulic structures analysis considering the Sustainable Development Goals. We welcome original research papers on topics such as: (1) the planning, design and analysis of hydraulic structures; (2) the performance analysis of hydraulic structures, taking into account climate change scenarios; (3) cocioeconomic benefits of hydraulic structures; (4) sustainable planning of hydraulic structures; (5) new hydraulic structure types; and (6) The role of dams in development.
