View Online / Journal Homepage Journal of Dynamic Article LinksC< Environmental Monitoring Cite this: DOI: 10.1039/c2em30032j www.rsc.org/jem PAPER Characteristics of nitrate in major rivers and aquifers of the Sanjiang Plain, China Yingjie Cao,ab Changyuan Tang,*b Xianfang Song,a Changming Liua and Yinghua Zhanga Received 16th January 2012, Accepted 6th July 2012 DOI: 10.1039/c2em30032j À The characteristics of nitrate (NO3 ) in major rivers and aquifers of the Sanjiang Plain, China were investigated by hydrogeochemical conditions, nitrogen isotope technique and CFCs trace. An overall À understanding on the sources and fate of NO3 in the surface water and the groundwater was obtained. À The NO3 concentrations in the surface water were low and no samples exceeds the WTO standards. À However, 11.4% of the groundwater samples exceeded the WTO standards, indicating local NO3 pollution in rural areas. Redox condition analysis revealed that most of the surface water had oxic condition, while for the shallow groundwater (mean well depth smaller than 30 m), the redox condition began to change into anoxic zone, and the deep groundwater (mean well depth larger than 50 m) 15 showed strong anoxic condition. The d N-NO3 data indicated soil N and fertilizer contributed the À major sources in the surface water, and NO3 in the groundwater mainly showed a manure origin. In the Songhua–Heilong River, dilution effect was dominating, while for the Wusuli River, it showed that À À mix with water contained excess of NO3 resulted in the NO3 concentration increased along the river. À Additionally, the NO3 transportation in the groundwater was analyzed by groundwater ages derived À from environmental tracer (CFCs) data. -

However, it is still unclear how water resources in high latitudes respond to climate change. In this study, the water resource data for 2021–2050 in the Naoli River Basin, a high-latitude basin in China, are calculated by using the SWAT-Modflow Model and future climate scenarios RCP4.5 and RCP8.5. The results show a decreasing trend. When compared to the present, future streamflow is predicted to decrease by 2.73 108 m3 in 2021–2035 and by 1.51 108 m3 in 2036–2050 in the RCP4.5 scenario, and by × × 8.16 108 m3 in 2021–2035 and by 0.56 108 m3 in 2036–2050 in the RCP8.5 scenario, respectively. × × Similarly, groundwater recharge is expected to decrease by 1.79 108 m3 in 2021–2035 and 0.75 − × − × 108 m3 in 2036–2050 in the RCP 4.5 scenario, and by 0.62 108 m3 in 2021–2035 and 0.12 108m3 − × − × in 2036–2050 in the RCP 8.5 scenario, respectively. -
Concentration and Species of Dissolved Iron in Waters in Sanjiang Plain, China
CONCENTRATION AND SPECIES OF DISSOLVED IRON IN WATERS IN SANJIANG PLAIN, CHINA 1 1 2 1 YAN B. , ZHANG B. , YOH M. AND PAN X. 1 Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, Changchun China 2Tokyo University of Agriculture and Technology, Tokyo, Japan ABSTRACT Water samples were collected from May to October in 2005-2008 to investigate the concentrations and fractions of dissolved iron in rivers, wetland and agricultural drainage in Sanjiang Plain, where land-use has been changing greatly since last fifty years although was formerly the largest concentrative distribution area of freshwater marshes in China. cross-flow technique was used to separate iron species by size fraction. The aim of this study is to reveal the iron fraction and to evaluate the effect of land-use change on transport and output flux of dissolved iron. The results show that marsh and marshy rivers exhibited higher concentrations of dissolved iron than in Amur River, Songhua River and Ussuri River and are the primary sources of dissolved iron for the rivers. Low molecular weight (LMW) iron was the major fraction of dissolved iron both in wetland and marshy streams, and 71% of LMW iron was in organic form in wetland. 73%-82% of dissolved iron was in the form of complexed iron in rivers. Ferrous iron accounted for 80.45% of dissolved iron in groundwater. The concentrations of high molecular weight and medium molecular weight iron (colloid iron) increased in paddy waters and ditch waters compared with in groundwater. Ferric and ferrous concentrations in Naoli River decreased between 1960’s and 2008. -

In this study, the pole-axis system (involving multi-level central places and roads) was recognized as a proxy of direct risk to wetlands stemming from human activities at the regional or watershed scale. In this respect, the pole-axis system and central place theory were adopted to analyze the spatial agglomeration characteristics of regional human activities. Soil erosion and non-point source (NPS) pollution, indicating the indirect effect of human activities on wetlands, were also considered. Based on these human disturbance proxies, which are considered regional risk sources to wetlands, incorporated with another two indicators of regional environment, i.e., vulnerability and ecological capital indexes, the regional ecological risk assessment (RERA) framework of wetlands was finally established. Using this wetland RERA framework, the spatial heterogeneity -
Sustainable Water Resources Planning & Management
SUSTAINABLE WATER RESOURCES PLANNING & MANAGEMENT UNDER CLIMATE CHANGE Lead Speaker: Young-Oh Kim Proceedings of the 37th IAHR World Congress August 13 – 18, 2017, Kuala Lumpur, Malaysia COMPARATIVE STUDY ON EFFECT OF EXTREAME WEATHER AND URBANIZATION TO FLOOD OF TYPICAL RIVERS IN JAPAN KENTARO YAMAMOTO(1), KENICHIRO KOBAYASHI(2) & SATORU OISHI(3) (1) Graduate School of Engineering, Kobe University, Kobe, Japan, (2,3) Research Center for Urban Safety and Security (RCUSS), Kobe University, Kobe, Japan, [email protected] ABSTRACT The impact of extreme rain, urbanization and snow amount variability in typical rivers in Hyogo prefecture as a microcosm of Japan is investigated. In Mukogawa River, urbanization greatly advanced around Sanda, but its influence on the outflow process was relatively small at Sanda in the main stream and large in a tributary of Nagano River. Therefore, when evaluating the influence of urbanization on the outflow of rivers, it is necessary to pay attention to the rate of change of land use in the entire catchment. In the Kishidagawa River, it was found that there was a big difference in the amount of snow water in the watershed in the spring season between the year of much snow and the year of little snow. In the years with little snow, it turns out that the use of stable snow melting water cannot be expected. Based on these results, we considered that the risk of water problems in the river basin of Japan will further increase with the change of climate and life style. From now on, what kind of action will be taken according to the risk and how to inform people of the risk will be a problem. -
