Study on Attribution Analysis and Response of Saltwater Intrusion in Modaomen Waterway During Dry Seasons by HUANG Chunhua, LIN Zhongyuan, ZOU Huazhi, HUANG Pengfei, XU Wei

“…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.…”

Analysis of Evolution of the Wetland Ecosystem of the Liaohe River Nature Reserve over the Past 40 Years and Its Driving Factors by SUN Xiangru, CHEN Jiabo, WANG Yanjie

“…The wetland in the Liaohe River Nature Reserve has played a crucial role in pollutant purification and biodiversity protection for the Liaohe River Basin.This paper reviews the evolution of the wetland ecosystem of the Liaohe River Nature Reserve over the past 40 years and analyzes the major factors driving the process,and puts forward measures for wetland conservation and prospects for future research.The results show that:From 1980 to 2010,the total wetland area showed a decrease trend.Except for the protected area at the estuary of the Liaohe River,the Liaohe River Nature Reserve suffered scarce plant resources and extremely low diversity of plant species,making it unsuitable to serve as a breeding habitat for most birds and fishes.From 2010 to 2020,with the rapid recovery in wetland area,the macro plant structure and diversity improved significantly,resulting in a substantial increase in bird and fish populations.Major natural factors driving the changes of wetland include temperature and precipitation,while human factors such as agricultural development,water project construction,oil and gas exploration,urbanization,and exotic species invasion play a central role in the process.Currently,key measures such as strictly guaranteeing ecological water demand,re-planting aquatic vegetation in land-water cross bedding and open water areas,and conducting integrated control of exotic species invasion through physico-chemical and ecological prevention measures should be taken to promote wetland conservation.The future research should focus on wetland developmental mechanism of the Liaohe River Nature Reserve based on the basin scale.…”

Export of Dissolved Organic Carbon from a Ponded Freshwater Marsh Receiving Diverted Mississippi River Water by R. D. DeLaune, C. B. Johnson, R. P. Gambrell, A. Jugsujinda

“…Based on a discharge of 1,000 ft3/sec (28.3 m3/sec), it was estimated that the equivalent of 7,335 kg/day of DOC would be exported from the marsh into Lake Cataouatche, located in the northern portion of the Louisiana Barataria Basin estuary. Results suggest that river diversion would likely increase the export of DOC from the marsh as compared to normal transport associated with rainfall and tidal exchange.…”

Oyster grower perspectives on green crab (Carcinus maenas) interactions: using applied social science to inform research and engagement by Kelsey Meyer-Rust, Lindsey Williams, Krystin Ward, Bonnie Brown

“…Research that informs the New Hampshire Aquaculture industry, which has grown significantly over the past few years, and helps the overall associated watershed community to keep Great Bay Estuary healthy is vital. Specific study of green crabs, Carcinus maenas, and their potential effects on oysters, Crassostrea virginica, is important to gain a better understanding of the impact invasive species may have on these ecologically and economically important bivalves. …”

Analysis of the Impact of Sewage Outfall on the Water Quality of Coastal Waters of Macau Based on MIKE21 Model by CHANG Ze, ZHANG Qionghai, JIANG Yu, SUN Ning, HE Rui, WANG Tengfei, WU Yaju, LONG Xiaofei

“…This paper simulates the impact of the sewage outfall of the Macau Taipa Wastewater Treatment Plant on the water quality changes in the nearby Lingding Ocean by the hydrodynamic module (HD) and the transmission diffusion module (TR) of the MIKE21 model,provides the boundary conditions for the local two-dimensional tidal current model (built by MIKE21) through the one and two-dimensional integrated tidal current model of the Pearl River Estuary area,and analyzes the impact of pollutant diffusion under normal discharge and accident discharge in terms of the three evaluation factors,namely COD_Cr (chemical oxygen demand),SS (total suspended solids) and NH₃-N (Ammonia-Nitrogen),under the “2005·6” flood combination and “2001·2” low water combination as the most unfavorable hydrological conditions.The results show that the water quality of main channel can meet the Class Ⅲ standard among the Sea Water Quality Standards (GB 3097—1997).With proper preventive measure,the out-of-limit water area under accidental discharge is less than 0.2 km².This model has good adaptability to the simulation of the diffusion of pollutants into the coastal waters of Macau,so it can better simulate the impact of sewage discharge on the water quality of the sea under the action of ocean tides,and serve as a basis and research direction for the establishment of sewage outfall.…”

Étude archéozoologique du quartier portuaire romain de Saint-Lupien à Rezé/Ratiatum (Loire-Atlantique) : les vestiges fauniques en pied de berge by Aurélia Borvon

“…The information provided by the biotopes frequented by shrimps slightly differs in that it indicates that the possible fishing grounds were located rather towards the inner estuary. Both of these conditions were possibly present in the outer estuary, bearing in mind, however, that the use of the Loire at that time was absolutely not the same as it is today. …”

Temporal and Spatial Distribution Characteristics of Rainstorm in China Based on CMORPH Integrated Precipitation by ZHAO Zixi, CHEN Zhihe

“…Based on the data set of China automatic station and CMORPH precipitation product fusion grid,this paper analyzes the spatial-temporal distribution characteristics and change trend of rainstorm number and rainstorm amount in 2008—2016 in China by the methods of rainfall object identification and Theil-Sen estimator.The research shows that there are 24 676 rainstorms in 2008—2016,including 20 135 small rainstorms,4 230 heavy rainstorms and 311 extremely heavy rainstorms.The rainstorm events in the whole year are at most in 2012 and at least in 2011with only 42,which occur frequently from May to September,accounting for 80.8% of the whole year.In 2010,2012 and 2014,the rainstorms in the coastal areas of South China and North China accounted for a relatively high proportion,some of which reached more than 60%.In 2008,2013 and 2016,the rainstorms in the coastal areas of South China and Hubei accounted for a relatively high proportion.From May to September,the rainstorm in China is widely distributed with large amount,mainly in the Pearl River Estuary,Northeast Jiangxi,and coastal areas of Hainan,Taiwan,Zhejiang and Fujian,with an annual average monthly rainstorm of about 150 mm.The number and amount of rainstorms are decreasing from the southeast coast to the northwest inland,with high value areas mainly in South China and the middle and lower reaches of the Yangtze River.The distribution of small rainstorms is similar to that of the total rainstorms.The heavy rainstorms are mainly concentrated in the coastal areas of Guangdong and Guangxi,the eastern Hainan and the southern Taiwan.Extremely heavy rainstorms are scattered in Southeast China.In the past 9 years,the number of rainstorms has increased,especially in South China and the middle and lower reaches of the Yangtze River,with significantly increased amount.…”
