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，在包括我国在内的世界许多地区，水质面临着越来越大的压力。许多长期的饮用水警告仍然对第一民族的保护区有效，藻华污染了我们的湖泊，加拿大的城市正在应对更频繁的洪水，这些洪水使污染物的负荷达到峰值。森林火灾加剧、降雨和降雪变化以及永久冻土融化进一步加大了对水生生物和人类用水的风险。水质面临多方面的挑战，需要有开放获取数据支持的适应性管理战略，这些数据可以很容易地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，可以自动发现、提取、巩固、处理、转换、分析和可视化水质参数、水流和流域化学负荷。CLAWAVE先进的计算和可视化能力将通过应用它们来说明(1)预测驱动温尼伯湖藻华的分水岭营养负荷，(2)评估与永久冻土融化相关的北部河流和湖泊水质风险，以及(3)估计加拿大河流向北冰洋排放的溶解有机碳的变化。CLAWAVE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的叙事和可视化功能将使所有加拿大人都能看到和解释水质数据，从而加强公众对水质监测和治理的参与。总的来说，CLAWAVE将加强加拿大在全球水资源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.
