“…Previous studies have shown that global warming leads to the intensification of the water cycle, which leads to more extreme annual and interannual precipitation extremes (Fowler et al ., 2021). This intensifies the pressure on water resources management and urban response to flood disasters (da Silva et al ., 2020). Unlike the abrupt change of extreme temperature, the abrupt change mechanism of the extreme precipitation indices is complicated.…”

The acceleration of global warming leads to frequent extreme weather events. The sensitivity of high-elevation regions to global warming makes their extremes more prominent. Based on the software Rclimdex1.0, 15 extreme climate indices from 120 meteorological stations in Yunnan from 1960 to 2019 were calculated. Trend analysis, correlation analysis, and cross-correlation analysis were used to investigate the spatiotemporal variation characteristics of these extreme climate indices. The results showed that, except CDD, other extreme precipitation indices were negatively correlated with the increase of elevation. The extreme warming indices (SU25, WSDI, TX90p, TN90p) showed an increasing trend with the increase of elevation, while the extreme cold indices (CSDI, FD0, TX10p, TN10p) showed a decreasing trend with the increase of elevation. The rate of nocturnal warming at high elevations is higher than that at low elevations. The change rate of extreme warmth indices (SU25, WSDI, TX90p, TN90p) and extreme cold indices (FD0, CSDI, TX10p, TN10p) was negatively correlated (p < .05) in all elevation ranges, and this correlation was most significant in the elevation range of 1,500-2,000 m. These results highlight that the rate of drying and warming at higher elevations is higher than that at lower elevations, providing case support and scientific basis for sensitivity of high-altitude regions to extreme climate.

“…Sea level rise is one of the most direct factors that escalate the extreme flood stages in the estuary waterways of the Pearl River Delta (Silva et al 2020). From 1906 to 2014, the mean high tide in the Lingding Yang Bay had increased by 0.40 m from 1.58 m in 19061.58 m in , to 1.62 m in 19361.58 m in , 1.66 m in 19541.58 m in , 1.82 m in 19711.58 m in , and 1.98 m in 20141.58 m in (Gong et al 2019.…”

The low-lying Pearl River Delta in South China is subject to severe flood threats due to watershed floods, sea level rise, and storm surges. It is still unknown to what extent and how far inland storm surges and sea level rise impact the extreme flood stages. This study investigated the coupling effect of flood discharge and storm surge on the extreme flood stages in the Pearl River Delta by using on site observations and simulations generated by the Hydrologic Engineering Center-River Analysis System model. The results show that flood discharges dominated the flood stages in the middle and upper Pearl River Delta, while the storm surges had maximum impact near the river mouth. The storm surges and flood stages showed a significant increase after 2002 in the Hengmen waterway. The design flood stages for the post-2002 period were 0.23–0.89 m higher than the pre-2002 ones at Hengmen at the six return periods from 5 to 200 years examined in this study. Their difference declined toward the upper waterway and reduced to zero about 23 km away from the Hengmen outlet. The coincidence of extreme flood discharges and storm surges further escalates the extreme flood stages in the lower 30 km of estuarine waterways. Our results quantify the severe threats due to sea level rise and intensified storm surges in the lower Pearl River Delta, and are significant for urban planning and designing and managing flood control facilities in the Pearl River Delta and in other coastal fluvial deltas.

“…It is worth noting that very often conditions change dynamically in a crisis situation, and the very assessment of such a situation requires the analysis of many factors. The complexity of the decision-making problem related to flood risk management determines the high degree of difficulty of the decisions made (Da Silva, Alencar, and De Almeida, 2020). It is also significant that these decisions usually concern human health and life, which additionally raises their importance.…”

Research on the interest of local governments in the use of artificial intelligence in flood risk management in Poland

The aim of the article was to analyse the degree of interest in the implementation of artificial intelligence methods in the area of crisis management related to flood risk in local government units in Poland. Pilot studies were carried out with the use of a questionnaire and direct telephone interview in 47 selected local governments located in Poland. The respondents assessed the current crisis management system and referred to the possibility of using artificial intelligence solutions in the analysed area. On the basis of the obtained results, it can be concluded that the surveyed entities show significant interest in the proposed solution and have specific expectations towards them. Most of the works devoted to flood risk management in Poland focus on solutions intended for the national level, not local one. The article aimed to highlight the need to fill this research gap.
