| 1 | Is urban development an urban river killer? A case study of Yongding Diversion Channel in Beijing, China显示文摘The high population and concrete environment alter urban areas by changing temperature, rainfall runoff, and water resource utilization activities. This study was conducted to investigate the water quality features of the Yongding Diversion Channel in Beijing, China, and its relationship with rainfall and urban development. Monthly water quality data were obtained from April to October of 2004 at monitoring sites of Sanjiadian, Gaojing, Luodaozhuang, and Yuyuangtan. The monthly water quality grades from 2007 to 2011 were also investigated and compared with those of other rivers. Dissolved oxygen and pH showed greater decreases after one or two moderate rainfall events than several light rainfall events. The potassium permanganate index(CODMn), ammonia nitrogen(NH3-N) and total phosphorus(TP) increased more after several light rainfall events than after one or two moderate or heavy rainfall events. Pollutant concentrations(CODMn, NH3-N, TP) in downstream regions showed greater changes than those in upstream areas after heavy rainfall events. Intense human activities around the channel greatly influenced the water quality of the channel in rainy season because of runoff pollution; however, heavy rainfall had a strong dilution effect on the pollutant concentrations in rivers. Overall, urban development has obviously deteriorated the water quality of the Yongding Diversion Channel as indicated by an increase in the water quality index from 3.22 in 2008 to 4.55 in2010. The Pearson correlation between monthly rainfall and water quality indices from 2007 to 2011ranged from 0.1286 to 0.6968, generally becoming weaker as rainfall and rainfall runoff became more random and extreme. | Xi Wang Junqi Li Yingxia Li Zhenyao Shen Xuan Wang Zhifeng Yang Inchio Lou | 2014 | Journal of Environmental Sciences2014，26，6： | 8 |

| 3 | Integrated water resources management for emergency situations: A case study of Macao显示文摘Integrated urban water management(IUWM) is a useful tool that can be used to alleviate water resource shortages in developing regions like Macao, where 98% of the raw water comes from China's Mainland. In Macao, scarce water resources deteriorate rapidly in emergency situations, such as accidental chemical spills upstream of the supply reservoir or salty tides. During these times, only the water from the two freshwater reservoirs in Macao can be used. In this study, we developed urban water management optimization models that integrated the raw water supply from the two reservoirs with various proposed governmental policies(wastewater reuse, rainwater collection, and water saving). We then determined how various water resource strategies would influence the urban water supply in Macao in emergency situations. Our results showed that, without imported raw water,the water supply from only the two Macao reservoirs would last for 7.95 days. However,when all the government policies were included in the model, the supply could be extended to 13.79 days. Out of the three non-conventional water resources, wastewater reuse is the most beneficial for increasing the Macao water supply, and rainwater collection also has great potential. | Jian Yong Huang Inchio Lou Ying Xia Li | 2016 | Journal of Environmental Sciences2016，28，12： | 2 |

| 5 | A system dynamics urban water management model for Macao, China显示文摘Urban water resources have been facing significant pressure from population growth,urbanization, and climate change. A system dynamics urban water management model was proposed to simulate the dynamic interactions between urban water demands and society,economy, climate, and water conservation. The residents' water conservation willingness was incorporated in the model and water-saving effects were quantified. The simulation results for Macao showed that population size was the main driving force for urban water demand. The change of temperature and precipitation has obvious effects on the landscape water demand.The water demand output is sensitive to the change in population, per capita demand, and temperature. Increased precipitation will reduce urban water demand and increased economic growth will increase water demand. By implementing integrated water conservation measures and improved water conservation willingness, water demand could be reduced by 17.5%. | Tong Wei Inchio Lou Zhifeng Yang Yingxia Li | 2016 | Journal of Environmental Sciences2016，28，12： | 1 |
