Urban flooding is a global water disaster resulting from the expansion of urban impervious surfaces and the strengthening of extreme precipitation events, especially in China. Nonetheless, few studies have focused on the spatial distributions of urban flooding characteristics and their variations in the context of climate change. In this study, eight critical metrics (i.e., maximum flooding volume, total overloaded manholes with different flooding volumes or durations, total flooding volume, mean and maximum flooding durations, maximum inundation area, and depth) are adopted to characterize the urban flood events. The impacts of climate change on these metrics are assessed for two periods, the 2030s (2020–2049) and 2070s (2060–2089), and compared with those in the baseline period (1976–2005). The Future Science City Park in Beijing, China, is selected as our study area. The results show that all four flood events are well simulated, with both efficiency coefficients and correlation coefficients being over 0.8. The number of overloaded manholes and the total flooding volume are projected to increase 19.3%–44.8% and 171%–716% under 20‐year rainfall events due to climate change in the two future periods. The spatial distribution of overloaded manholes with different increased flooding volumes is projected to expand to almost the whole area from the region with lowland and limited drainage capacity. Furthermore, the maximum inundation area and depth are projected to increase obviously. This study will be helpful for designing and improving the drainage system, controlling urban flooding, and adapting to climate change.

Establishing a modern water rights system (WRS) that is suited to the Strictest Water Resources Management System (SWRM) is an important reform in China's water resources management in terms of addressing current water issues. However, there are still several problems in the construction of a WRS, such as ambiguity in the definition of water rights, weakness in the infrastructure of water rights and imperfect WRS legislation. Moreover, water rights allocation (WRA) and water rights trading (WRT), which are two core components of water rights, still have some problems that remain to be solved. The ‘Three Red Lines’, which make up the core of the SWRM, are expounded upon, and the relationship between the WRS and the SWRM is analyzed. Finally, some appropriate recommendations based on the ‘Three Red Lines’ are provided to perfect the WRS so that it is suitable for the SWRM. In this paper, we conclude that the WRS is a type of water resource management that can effectively solve the current water issues in China. Significant efforts have been made in the construction of the WRS, which has achieved remarkable success in a period of exploration and practice in China. The construction of the WRS supports sustainable social and economic development and results in harmonious relationships between humans and nature.
