“…In recent years, with the increase in temperature and precipitation in the northwest region of China [7,8], the heat resources in the Ningxia Hui Autonomous Region located in the eastern part of the region have been ever more abundant. At the same time, the amount of evapotranspiration has also increased, resulting in an increase in extreme precipitation events in Ningxia, and the precipitation pattern has undergone subtle changes [9][10][11]. The non-stationary changes caused by extreme precipitation may cause a certain degree of damage to the infrastructure of water conservancy construction projects that have been in use for a long time, such as earth and rock dams and check dams, and even pose a risk of failure [12].…”

To analyze the operation risk of check dams under extreme precipitation conditions, taking Ningxia area as an example, this paper carried out a risk assessment of check dams under extreme precipitation conditions in Ningxia through data collection, hydrological statistics, numerical simulation, and other methods. The conclusions are the following: (1) By the end of 2020, about 40% of the silt reservoir capacity of check dams in various water and soil conservation zones in Ningxia has been accumulated. During 1966–2020, the extreme precipitation and frequency of extreme precipitation in Ningxia increased while the intensity of extreme precipitation decreased. The extreme precipitation in Ningxia increased year by year and lasted longer. (2) Under two future scenarios of RCP4.5 (the full name of RCP is Representative Concentration Pathway) and RCP8.5, the extreme precipitation threshold in Ningxia is gradually decreasing from south to north. Extreme precipitation in the future will bring high risk to the operation of check dams in Ningxia. The results of this paper can provide a scientific basis for the operation and management of check dams in Ningxia.

“…Inadequate rainfall is a key factor in triggering droughts, as replenishment of surface water sources is mainly dependent on rainfall. The Yellow River is the second largest river in China and the basin has a high evapotranspiration capacity, resulting in drought events in the basin that are widespread, prolonged and frequent [4] . Therefore, rapid and accurate rainfall monitoring is of great practical importance.…”

The Standardized Precipitation Index (SPI) accurately reflects the drought phenomenon, closely matches the real situation, and proves to be a reliable drought monitoring tool. This paper employs geodetector methodology to explore the drivers of spatial heterogeneity in the SPI, calculated using 1-km resolution Global Precipitation Measurement (GPM) data, within the Yellow River Basin from 2001 to 2019. Besides precipitation, which emerges as the predominant driver influencing the SPI, the individual explanatory power of all other factors is notably weak, each contributing less than 20%. However, it is observed that the combined influence of multiple factors on SPI12 generally surpasses that of any single factor. Notably, the interaction between altitude and precipitation exhibits the most substantial effect. These findings hold significant implications for the efficient management of water resources and the preservation of the ecological environment within the Yellow River basin.

“…China has also historically experienced frequent meteorological and hydrological drought incidences historically, especially in the ecologically fragile and geographically complex Yellow River Basin (YRB), profoundly influencing agricultural, economic and social development. Numerous scholarly works have examined drought patterns within the YRB region [8][9][10][11]. For instance, Zhu et al [12] assessed integrated drought conditions in the YRB utilizing a comprehensive drought index, ascertaining a drying trend inclination over recent decades, with heightened aridity in upstream and northern sections.…”

The primary innovation of this study lies in the development of an integrated modeling framework that combines downscaled climate projections, land-use-change simulations, and copula-based risk analysis. This framework allows for the assessment of localized sub-seasonal and seasonal drought hazards under future scenarios. The BCC-CSM1-1 climate model projections from the NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) dataset are utilized to represent the future climate for 2025–2060 under RCP 4.5 and 8.5 scenarios. The CA-Markov model is employed to predict future land-use-change distributions. The climate–land use–drought modeling nexus enables the generation of refined spatio-temporal projections of meteorological and hydrological drought risks in the Yellow River Basin (YRB) in the future period of 2025–2060. The results highlight the increased vulnerability of the upper YRB to sub-seasonal meteorological droughts, as well as the heightened sub-seasonal hydrological drought risks in the Loess Plateau. Furthermore, downstream areas experience escalated seasonal hydrological drought exposure due to urbanization. By providing actionable insights into localized future drought patterns, this integrated assessment approach advances preparedness and climate adaptation strategies. The findings of the study enhance our understanding of potential changes in this integral system under the combined pressures of global climate change and land use shifts.
