Special Issue Information

Dear Colleagues,

Flooding is an extreme hydrological process in climatic events with enormous impacts on human society and ecosystems. Thus, assessing flood risks is critical for flood hazard mitigation and prevention. With the intensification of climate change and the impact of human activities, the concept of flood risk management and prevention is also changing. The traditional flood management method driven by reducing vulnerability has begun to change to flood resilience management. Flood risk assessment has new problems and new demands, such as paying more attention to the flood control risk of small and medium-sized rivers in hilly areas, large-scale water transfer projects, small reservoirs, etc. This Special Issue mainly focuses on the application of new concepts, new theories, and new methods in comprehensive flood risk assessment in important areas related to flood impact, with a view to providing systematic technical measures for flood hazard prevention and control. We invite submissions including, but not limited to, the following topics:

  1. Comprehensive flood risk assessment-related theories, methods, and technical frameworks;
  2. Flood control risk assessment of large-scale water diversion projects;
  3. Flood risk assessment for small reservoirs and the impact of discharge on the downstream;
  4. Flood risk assessment methods and techniques for small watersheds in hilly areas;
  5. Flood risk quantitative assessment method;
  6. Comprehensive assessment of flood risk from the perspective of resilience;
  7. Flood risk prevention measures and benefit evaluation.

Multi-objective reservoir operation of reservoir flood control involves numerous factors and complex model solving, and exploring effective methods for solving the operation models has always been a hot topic in reservoir optimization operation research. The Multi-Objective Ant Lion Algorithm (MOALO) is an emerging heuristic intelligent optimization algorithm, but it has not yet been applied in reservoir optimization operation. Testing the effectiveness of this method on multi-objective reservoir scheduling and further improving the optimization performance of this method is of great significance for enhancing the overall benefits of reservoir operation. In this study, MOALO is applied to the optimal scheduling of reservoir flood control. To increase the search efficiency of MOLAO, the advanced MOALO method (AMOLAO) is proposed by reconstructing the search distribution in MOALO using a power function. Taking the Songshu Reservoir and Dongfeng Reservoir in the Fuzhou River Basin in Dalian City as an example, MOALO, AMOLAO, and other two traditional methods are applied for solving the multi-objective reservoir operation problem. Results show that the AMOALO method has high search efficiency, strong optimization ability, and good stability. AMOALO performs better than MOALO and the two traditional methods. The study provides an efficient method for solving the problems in multi-objective reservoir operation. Full article

Breach geometry is one essential feature for flood modelling in the channel–levee–floodplain system. It is hard to accurately predict the breach geometry because of its high uncertainty. However, due to the fact that breach geometry direct impacts the flow through the breach, the water surface profile in the channel and the flood hazard factors within the floodplain are changed with the breach geometry. To explore the impacts of breach width (one feature of the breach geometry) on the channel–levee–floodplain system, we took the Cinan Feiyou Flood Control Protection Area (CNFY-FCPA) in the middle reach of the Huaihe River Basin as the study area. We constructed a coupled 1D-2D hydrodynamic model to simulate the flooding with a series of breach-width scenarios. According to the simulation results of the models, we quantitatively analyzed the impacts of breach width on the inflow through the breach, fluvial flood process, and flood hazard factors in the CNFY-FCPA. The results indicate that (i) the relationship between the peak discharge (and inflow volume) and breach width was approximate to an S-shaped curve, while the peak discharge, inflow volume, and duration per unit width decreased with the wider breach; (ii) the breach caused a decrease in the water surface profile along the entire river sections; and (iii) while the breach width exceeded a certain width, the inundation area was nearly stable without changing with wider breach. The certain width was not the same in different rivers of 300 m in the Yinghe River and of 500 m in the Huaihe River. The research results can provide a scientific basis for flood-control and disaster-reduction decision making. Full article
