CLAWAVE - Chemical load assessments for watersheds: automation and visualization experience

清洁的水支持健康的生态系统，社区和经济。然而，在世界许多地区，包括在我国，水质日益受到压力。许多长期的饮用水管制仍然对第一民族的保护区有效，藻类大量繁殖正在污染我们的湖泊，加拿大的城市正在应对更频繁的洪水，洪水调动了污染物的峰值负荷。森林火灾的加剧、降雨量和降雪量的变化以及永久冻土的融化进一步加大了水生生物和人类用水的风险。水质所面临的多方面挑战要求采取适应性管理战略，这些战略由开放获取的数据提供支持，这些数据很容易转化为可操作的知识。拟议的CLAWAVE项目将产生一个用户友好的工具包，自动发现，提取，合并，处理，转换，分析和流域水质参数，水流和化学负荷的可视化。CLAWAVE的先进的计算和可视化能力将通过应用它们来说明（1）预测流域营养负荷驱动藻类水华在温尼伯湖，（2）评估风险的水质与永久冻土融化相关的北方河流和湖泊，和（3）估计溶解有机碳的变化排放到北冰洋的加拿大河流。CLAWAVE的基于网络的应用程序将支持设计长期战略，以管理加拿大水质恶化的不利影响。CLAWAVE的讲故事和可视化能力将使水质数据对所有加拿大人可见和可解释，从而加强公众对水质监测和治理的参与。总体而言，CLAWAVE将加强加拿大在全球水研究方面的领导地位。

Clean water supports healthy ecosystems, communities, and economies. However, in many regions of the world, including in our country, water quality is increasingly under pressure. Numerous long-term drinking water advisories remain in effect on First Nations' reserves, algal blooms are fouling our lakes, and Canadian cities are coping with more frequent floods that mobilize peak loadings of pollutants. Intensifying forest fires, changes in rainfall and snowfall, and permafrost thawing are further amplifying risks to both aquatic life and human water uses. The multifaceted challenges facing water quality call for adaptive management strategies supported by open access data that are readily transformed into actionable knowledge. The proposed CLAWAVE project will produce a user-friendly toolkit that automates the discovery, extraction, consolidation, treatment, transformation, analysis, and visualization of water quality parameters, water flows, and chemical loads in watersheds. CLAWAVE's advanced computational and visualization capabilities will be illustrated by applying them to (1) predict the watershed nutrient loads driving algal blooms in Lake Winnipeg, (2) assess the risks to water quality of northern rivers and lakes associated with permafrost thawing, and (3) estimate the changing discharge of dissolved organic carbon to the Arctic Ocean by Canadian rivers. CLAWAVE's web-based applications will support the design of long-term strategies to manage the adverse effects of water quality deterioration in Canada. CLAWAVE's storytelling and visualization capabilities will make water quality data visible and interpretable to all Canadians and, hence, enhance public participation in water quality monitoring and governance. Overall, CLAWAVE will strengthen Canada's global water research leadership.
