Precipitation Concentration in Highly Urbanized Regions — Case Study of Yangtze River Delta Urban Agglomeration by LIN Zequn, WANG Dayang, ZHANG Zhi, WANG Dagang

“…The Theil-Sen Median slope estimation and Mann-Kendall significance test are utilized for trend analysis,and a correlation analysis is employed to explore the relationship between urbanization levels and precipitation concentration.The results show that:① the root mean square error between the GI calculated from climate hazards Group infrared precipitation with station data (CHIRPS) and the station data results is 0.036,significantly lower than the results from CMFD data (0.067) and MSWEP data (0.083),which indicates that CHIRPS data demonstrates optimal applicability.② The unevenness of precipitation in the Yangtze River Delta urban agglomeration gradually increases from south to north,with a significant increasing trend in the central and western parts of the agglomeration.The intra-annual distribution of precipitation in the study area has become more concentrated,leading to an increased likelihood of extreme precipitation events.③ Urbanization is likely to promote the concentration of precipitation.The rapid development of cities enhances precipitation unevenness,especially in areas such as Nanjing,Wuxi,and Zhenjiang,making them more susceptible to urban flooding and related disasters.The findings of this research have practical implications for urban flood control design,urban road drainage system planning,and the development of emergency response plans for urban flood control.…”

A New Concept Proposal of the Tidal Level Designed for the Security of Coastal Levee during Storm Surge — Taking the Lingdingyang Estuary as an Example by LI Bin, HE Yong, FANG Shenguang

“…Based on the analysis of the design frequency tidal levels,storm surge water increase and flood inflow upstream of control stations in Lingdingyang Estuary over years,it showed that the tidal levels of designed frequency of 0.5%~2.0% raised from 0.2 to 1.0 m in recent years,the extreme storm surge elevations exceed 2.5 m commonly,and the current tidal level difference of adjacent design frequency was less than 0.2 m.During the emergence of the extreme storm surge elevation in the estuary flood upstream would not be appeared simutaneously,while the moderate tide was most likely encounterred.Therefore,there were some problems in the application of design frequency tidal levels in estuarine waters,such as the small tidal level difference between adjacent frequencies,the severe frequency jump of tide level during strong typhoon,and the failure to directly reflect the leading role of the extreme storm surge elevation in the elevation design of coastal levee.The concept of the tidal levels designed for storm surge security of coastal levee was proposed in the paper,which were composed of multi-year average high tidal level and the maximum extreme storm surge elevation,clearly and easily to be used.It highlights the main role played by coastal levee to resist the disaster by strong storm surge.The calculated values were close to and slightly more than the designed tidal levels of 100~200 year return period of main stations in the mouth of Lingdingyang estuary,Shiziyang water area and delta river network area after reviewed in 2020,proving its safety and reliability.The reviewed tidal levels of designed frequency in the Chiwan station in 2020 were likely too high by analysis preliminarily.The tidal level designed for storm surge security of coastal levee could be widely used in reinforcement design,safety risk assessment in storm surge and storm surge disaster warning and response.…”

Land Use Change in Zhengzhou during 2000—2021 and Its Impact on Comprehensive Runoff Coefficient by JIANG Yu, WANG Xinghan, ZHOU Xiaoxue, CHEN Jingxia, YU Guosong, WU Dan, KUANG Gaoming, CHEN Haihua, LI Shubo, BAI Chunxiang, DU Dejie, LAN Zhenwei

“…Flood disasters are a prominent water safety problem for the major cities in China.Land use change has a great impact on the formation of flood disasters,and the comprehensive runoff coefficient is an important factor in response to the hydrological process of floods.Therefore,studying land use change and its impact on the comprehensive runoff coefficient is of great significance.With land use classification data from three phases of Landsat remote sensing images of Zhengzhou for 2000—2021,the spatio-temporal evolution characteristics of land use in Zhengzhou were analyzed,and the regional comprehensive runoff coefficient and the urban ground hardening rate were calculated.The following observations could be made from the results:① The land use in Zhengzhou underwent drastic changes during 2000—2021.Specifically,the area of construction land increased by 1 425.97 km²,while those of forest/grassland and cultivated land decreased by 777.25 km² and 810.88 km²,respectively.② The percentage of the total area of land use conversion in Zhengzhou during 2000—2021 was 43.39%,and the conversion mainly took place among cultivated land,forest/grassland,and construction land.During the period of 2000—2014,the land use conversion was mainly from cultivated land and forest/grassland to construction land and from forest/grassland to cultivated land.During the period of 2014—2021,it was mainly from cultivated land to forest/grassland and construction land and from forest/grassland and construction land to cultivated land.③ During 2000—2021,the urban ground hardening rate of Zhengzhou increased from 12.32% to 31.14%,and its comprehensive runoff coefficient grew from 0.24 to 0.40.…”
