Layout Optimization of Pajiang River Flood Storage and Detention Area Based on Joint Flood Control and Operation Model by XIN Yue, LIAO Xiaolong, ZHONG Yixuan, QUAN Xujian, YU Baishun

“…Flood storage and detention areas play an irreplaceable role in flood control and disaster mitigation in river basins.However,the significant weakness of safety layout and safety facility construction of flood storage and detention areas in Pajiang River results in difficult decision making and great loss in flood control application,constraining the application effect of flood control.To this end,this paper proposes a layout optimization scheme by combining the flood control capability in each dike and socioeconomic conditions in the studied detention areas.Then,joint flood control and operation model related to Feilaixia Reservoir-Pajiang River flood storage and detention areas is employed to analyze and calculate the flood control effects before and after the optimized layout schemes.Finally,the recommended layout optimization scheme of the detention areas is selected by comprehensive analysis.Results show that by adding Baishatang dike and Guanluchun dike as safety areas of Pajiang River Basin,the potential inundation cultivated area decreases by 163.2 hm² and the number of people prone to flood risks decreases by 3 002.This indicates the optimized layout scheme can reduce flood detention loss and ensure flood control safety.The results provide technical references and an approach for layout optimization of other detention areas.…”

Changes of Runoff in Bosten Lake Basin and Annual Distribution Characteristics by MO Yinxue, YAO Junqiang, QU Lianglu, ZHOU Guixiang

“…Based on the monthly measured runoff data of Kaidu River and Huangshui Gulley of Tarim River Basin Administration from 1956 to 2021,the variation and annual distribution of runoff in Kaidu River and Huangshui Gulley are studied by the methods of concentration,linear regression,and Mann-Kendall rank test.The results show that the annual runoff of the Kaidu River and the Huangshui Gulley shows an increasing trend,and the annual runoff shows a gradual change of “decreasing,increasing,and decreasing”.The annual runoff of Kaidu River and Huangshui Gulley had abrupt changes in 1996 and 1994,respectively.After abrupt changes,the annual average runoff was higher than that before abrupt changes.The monthly runoff shows an increasing trend,and the monthly runoff increases significantly in winter.The monthly runoff distribution is unimodal throughout the year,and the annual runoff is mainly concentrated in summer,with the peak runoff in July.The mean monthly runoff after the abrupt changes was higher than that before the abrupt changes and multi-year averages.The characteristic values of each index show that the annual runoff distribution of Kaidu River has a uniform development trend,while that of Huangshui Gulley is still concentrated.The runoff of Kaidu River is mainly affected by precipitation and temperature,and that of Huangshui Gulley is mainly affected by temperature change.…”

Comparison of Methods for Determining Catchment Area Threshold for Water System Extraction by ZHENG Jiawei, CHEN Xingwei, LI Xiaocheng, RUAN Weifang

“…Most of the methods using digital elevation models (DEM) to extract water systems require the determination of catchment area thresholds.For a better understanding of the rationality and applicability of several commonly used determination methods of the catchment area threshold for water system extraction,the distance error between the real river source and the extracted one is used as a criterion to determine the rationality of the real water system extraction methods.Four main methods,namely,the drainage density method,the water-system fractal dimension method,the method of the minimum error at the river source,and the channel branching ratio method,are selected,and the Jinjiang River Basin on the southeast coast is taken as an example.The distance errors between the extracted river sources by different methods and the real river sources are compared.The results show that the visual discrimination of the catchment area threshold used by the drainage density method,water-system fractal dimension method,and channel branching ratio method has a large uncertainty,and the distance errors are large.In the method of the minimum error at the river source,the catchment area threshold is determined according to the minimum distance error between the extracted river source and the real one,which is unique.Hence,it is a more reasonable method among the four DEM-based real water system extraction methods.…”

Research on Spatiotemporal Evolution and Driving Factors of Extreme Climate in Guangdong-Hong Kong-Macao Greater Bay Area by GUO Shan, ZHANG Dawei, WANG Yadi

“…In recent years,frequent extreme climate events have become the focus of attention of the world.Studying the spatiotemporal evolution of extreme climate in the Guangdong-Hong Kong-Macao Greater Bay Area is of great significance for timely and accurate disaster prevention and mitigation forecasts and early warnings.On the basis of the precipitation and temperature data from 1961 to 2016,this paper uses the heuristic segmentation method,Mann-Kendall trend test,and cross wavelet method to analyze the spatiotemporal evolution of extreme climate in the Guangdong-Hong Kong-Macao Greater Bay Area and its relationship with driving factors.The results reveal that extreme precipitation and temperature changes are potentially related to sunspots and large-scale circulation factors including the multivariate ENSO index (MEI) and interdecadal Pacific oscillation (IPO),but their effects on extreme climate are different.Climate change will continue to profoundly affect urban construction and development.For future studies on the climate change in the Guangdong-Hong Kong-Macao Greater Bay Area,attention should be paid to the impact assessment of climate change in the Pearl River Basin and typical regions,and the research on the occurrence mechanism,risk assessment,countermeasures of extreme weather in the basin should be strengthened to reduce the damage of extreme climate events.…”

Applicability Analysis of Machine Learning Model in Hydrological Forecasting in Karst Areas by ZHAO Zejin, SUN Wei, ZHOU Bin, ZHANG Xuan, WANG Gaoxu, WU Wei, LI Wenjie, YAO Ye

“…For hydrological forecasting in karst areas,existing research mainly uses hydrological models based on physical mechanisms,while rare research focuses on machine learning models.To explore the applicability of machine learning models in karst areas, this paper utilizes the LSTM model and random forest model to simulate the daily runoff and field floods at Tangdian hydrological station,using the Shadian River basin in Yunnan Province as the study area.The modified Xin'anjiang model for karst areas is taken as a reference.The results show that both the machine learning model and the modified Xin'anjiang model have achieved good results in simulating the daily runoff process, with the LSTM model showing better simulation results.In the simulation of floods,the modified Xin'anjiang model achieves Class A forecast accuracy.The machine learning models have better forecast results for the 6-hour forecasting period than the modified Xin'anjiang model,while the forecast results for the 24-hour forecasting period do not meet the accuracy requirements of the forecast operation.The study provides a reference for hydrological forecasting in karst areas by studying the characteristics and forecasting accuracy of two machine learning models and a hydrologic model.…”
