Special Issue Information

Dear Colleagues,

The major theme of the conference is the “Water–Energy–Sustainability Nexus”. The water, energy, and food security nexus means that water security, energy security, and food security are inextricably linked and that actions in any one area usually have an impact in one or both of the others. As the world population approaches 8 billion, with increasing demands for basic services and a growing desire for higher living standards, the need for more conscious stewardship of the vital resources required to achieve these services and desires has become both more obvious and urgent. While the focus of this Special Issue is the water–energy–sustainability nexus, authors are welcome and encouraged to submit their papers on topics such as, but not limited to, the following:

  • The development of new alternative fuels
  • Biofuel processing technologies
  • Novel biofuel feedstocks
  • New perspectives of alternative fuels
  • New developments in microalgae for biofuel production
  • Biohydrogen, biobutanol, bioethanol, and other biofuel production techniques
  • Physical and chemical properties of alternative fuels and their improvement
  • Predicting the properties of alternative fuel blends
  • The modelling and experimental investigation of engine performance and the emission of alternative fuels
  • Waste to energy
  • Wastewater treatment
  • Bioelectorchemical systems
  • Wind and solar energy
  • Photovolatics and their applications
  • Novel nano-catalysts for biodiesel production
  • Socioeconomic and environmental impacts of alternative fuels
  • Biomass industries’ performance
  • Future challenges and directions, and the economics, of alternative fuels
  • Biofouling control
  • Sponge cities/water-sensitive cities
  • LID technologies
  • Urban water management in the control of water and the reuse of water resources
  • Watershed management
  • Nanotechnology for remediation
  • Sustainable development in water and energy use
  • Novel membrane processes for biofuels, energy, and environment applications

In recent decades, solving complex real-life optimization problems has attracted the full attention of researchers. Dam and reservoir operation rules are considered one of the most complicated optimization engineering problems. In fact, the operation rules of dams and reservoirs are multisystematic and highly stochastic and have highly nonlinear system constraints due to the direct influence of environmental conditions: Therefore, these rules are considered highly complex optimization problems. Recently, metaheuristic methods inferred from nature have been broadly utilized to elucidate the way optimal solutions are provided for several complex optimization engineering applications, and these methods have achieved interesting results. The major advantage of these metaheuristic methods over conventional methods is the unnecessity to identify a particular initial condition, convexity, continuity, or differentiability. The present study investigated the potential of using a new metaheuristic method (i.e., the crow algorithm (CA)) to provide optimal operations for multireservoir systems, with the aim of optimally improving hydropower generation. A multireservoir system in China was considered to examine the performance of the proposed optimization algorithm for several operation scenarios. The results obtained the average hydropower generation by considering all examined operation scenarios based on the operation rule achieved using the CA, which outperformed the other metaheuristic methods. In addition, compared to other metaheuristic methods, the proposed CA lessened the time required to search for the optimal solution. In conclusion, the proposed CA has high potential for achieving optimal solutions to complex optimization problems associated with dam and reservoir operations. Full article

In order to reduce stormwater runoff, permeable brick was prepared by compounding with fly ash and steel slag as the main substrate. The study found that the amount of steel slag has a significant influence on the compressive strength of permeable brick. When the proportion of steel slag is 6.5%, the compressive strength of permeable brick after 28 days curing can reach 26.32 MPa. The strength of permeable brick decreases with the increase of fly ash content, but the permeability coefficient increases significantly. The results show that the compressive strength and permeability coefficient of permeable bricks can reach a good level when the composite ratio of steel slag is 6%, fly ash is 30%, and the design target of porosity is 20%.
