Pollution in three Gorges reservoir and water warning: ten minutes to complete emergency calculation

Wuhan Xinhua News on March 18, "in three Gorges reservoir area and the upper reaches of river water environmental risk assessments and early warning technology research and demonstration" achievements report meeting recently held at Wuhan University. Experts said the study through the integrated automatic monitoring system of the Internet of things, build a real-time, automated, business-oriented water environmental risk management platform, for water quality assessment and pollution control, emergency pollution risks and "blooms" risk early warning, emergency response and disaster reduction to provide technical support.

Project leader College of resource and environment science, Wuhan University Professor Zhang Wanshun introduced as a national water pollution control and management of major science and technology projects, and research for three Gorges reservoir area and the upper reaches, covering 1 million square kilometer basin ranges, 663 km Yangtze River.

Research personnel in full research Three Gorges library district water environment risk features of based Shang, around environment big data acquisition, and cloud storage, and big scale simulation calculation, and high performance calculation, and basin risk assessment and warning and business of software platform, content, for has technology storming, formed three gorges library district strong spatio-temporal variation surface source pollution simulation technology, and three gorges library district "water China" risk warning simulation technology, and three gorges library district full basin of empty-to-water integration water environment model system, series results.

From State Three Gorges do, and Taihu Lake Basin Authority, units of experts think, this items research introduced big data and high performance calculation, building has library district basin non-points source pollution model and storage pollutants pass volume accounting model, and burst sex and cumulative type risk evaluation and warning model, will burst emergency simulation forecast calculation time improve to 10 minutes within, and simulation dimension degrees by a dimension upgrade to three dimensional, great to improve has burst emergency of response time and forecast precision; in cumulative sex risk assessment in the, consider meteorological, and Combined effects of pollution and sediment process in basin-wide scale to accurately assess the "blooms" of risk.

Zhang Wanshun introduced, research results have been in the business of running Chongqing, Sichuan and other environmental protection departments, realization of hydrology, water quality and meteorological data automated collection, processing and analysis, and real-time simulation of water environment and water environment quality assessment, water environmental risk warning and information services.

三峡库区污染及水华预警：十分钟完成突发应急测算

　　新华网武汉3月18日消息，“三峡库区及上游流域水环境风险评估与预警技术研究与示范”课题成果汇报会日前在武汉大学举行。与会专家表示，此项研究通过集成物联网自动监测体系，构建了实时化、自动化、业务化的流域水环境风险管理平台，为水环境评价及污染控制、突发污染风险以及“水华”风险预警、应急减灾等提供技术支撑。

　　课题负责人、武汉大学资源与环境科学学院张万顺教授介绍，作为国家水体污染控制与治理科技重大专项，课题研究范围为三峡库区及上游流域，涉及100万平方公里流域范围，663公里长江干流河段。

　　科研人员在充分研究三峡库区水环境风险特点的基础上，围绕环境大数据采集、云存储、大尺度模拟计算、高性能计算、流域风险评估与预警以及业务化软件平台等内容，进行了技术攻坚，形成三峡库区强时空变异面源污染模拟技术、三峡库区“水华”风险预警模拟技术、三峡库区全流域的空－地－水一体化水环境模型体系等一系列成果。

　　来自国务院三峡办、太湖流域管理局等单位的专家认为，此项研究引入大数据和高性能计算，构建了库区流域非点源污染模型和入库污染物通量核算模型、突发性和累积型风险评价与预警模型，将突发应急模拟预测计算时间提高到10分钟以内、模拟维度由一维提升到三维，极大地提高了突发应急的响应时间和预测精度；在累积性风险评估中，考虑气象、面源、底泥等综合影响过程，在全流域大尺度范围内准确地评估“水华”的发生风险。

　　张万顺介绍，课题成果已在重庆、四川等环保部门业务化运行，实现了水文、水质、气象等业务数据自动搜集、处理和分析，并能实时开展水环境情景模拟、水环境质量预报评估、水环境风险预警及信息发布等服务。
