Study on Attribution Analysis and Response of Saltwater Intrusion in Modaomen Waterway During Dry Seasons
Published 2023-01-01“…Under the influence of climate change and human activities, the saltwater intrusion in the Modaomen Estuary Waterway has intensified significantly,which has greatly threatened the safety of the water supply in the Guangdong-Hong Kong-Macao Greater Bay Area.Based on the daily exceedance time data of seven stations in the Modaomen Waterway,daily maximum tidal range,volume of runoff, mean sea level,cross-shore wind,and alongshore wind from 2004 to 2016,empirical orthogonal function (EOF) analysis and univariate and multiple linear regression analysis were carried out to reveal the response relationship between the saltwater intrusion and the impact factors and quantify the contribution of each impact factor.The results show that the maximum contribution to the saltwater intrusion is the tidal range,followed by the volume of runoff, which can explain 30% and 28% of the diurnal variation of the exceedance time, respectively.The contribution of wind to the saltwater intrusion is slightly greater than that of the mean sea level,and the contribution of wind and mean sea level to the saltwater intrusion is 12% and 11%,respectively.The effect of cross-shore wind is slightly greater than that of alongshore wind.The peak of Modaomen saltwater intrusion appears in 3.2 days after the minimum tidal range,and the salinity of Modaomen Waterway is not suppressed until 1.8 days after the increase in the volume of runoff of Gaoyao station.This paper can provide theoretical support for watershed scheduling and saltwater intrusion forecast.…”

Application of Improved Fisher Optimal Segmentation Method Based on Combined Weight Method in Reservoir Flood Season Staging
Published 2024-01-01“…In Fisher optimal segmentation method,multi-index weighting only considers a single objective weighting method.To overcome the shortcoming,this paper introduces the entropy weight method based on information theory,the coefficient of variation method based on statistical principle,and the CRITIC weighting method in the calculation of index weight.It proposes the Fisher optimal segmentation method based on combined weight.Taking Shuibuya Reservoir as an example,five indicators are selected,including the average flow in ten days,the number of occurrences of the maximum peak flood flow,the maximum one-day flood volume in ten days,the maximum three-day flood volume in ten days,and the maximum seven-day flood volume in ten days.Then the Fisher optimal segmentation method is applied to divide the flood season,and the staging results are compared with the staging results by a single objective weighting method.It is determined that the flood season is divided into three optimal periods.The pre-flood season is from May 1 to June 10,the main flood season from June 11 to July 31,and the post-flood season from August 1 to September 30.The results show that the combined weight method takes into account the advantages of the entropy weight method,the coefficient of variation method,and the CRITIC weighting method.The method can intuitively distinguish the influence degree of different indexes on flood season staging and is suitable for determining multi-index weight in the Fisher optimal segmentation method.…”
