项目摘要
As climate warming drives rapid cryosphere decay in mountain environments, it is leading to major hydrological changes that affect biodiversity, water resources, and ecosystem services. These adverse impacts are observed as far as hundreds of kilometers downstream of the water sources as mountainous cryospheric features (e.g. glaciers) represent major sources of water in rivers during the hot and dry months of the year. Despite the urgent necessity for adaptation strategies, there is still a clear need for reliable projections of these hydrological changes. The lack of understanding of hydrological processes in glacierized catchments is the most cited cause for the limited accuracy in projections. In this context, the long-term objective of my proposed research program is to improve the understanding of hydrological processes in alpine glacierized catchments in order to improve predictions of future changes in water resources in a reliable way. Five sub-objectives are proposed, three focus on the scale of a study watershed: (i) quantifying the contributions and processes that control watershed outflows from features such as rock glaciers, debris-covered ice, and icings; (ii) characterizing the interconnections between these features, groundwater and surface runoff; and (iii) characterizing their susceptibility to climate change. And two sub-objectives focus on the regional scale: (iv) measuring and intercomparing the extent and evolution of those features across multiple watersheds; and (v) developing a regional overview of cryosphere-hydrologic interactions. My research program will focus on the St-Elias Mountains in southwest Yukon, and the study site will be the Grizzly Creek, a 32 km2 glacierized catchment situated in the Kluane National Park and Reserve. The study site has many interrelated cryospheric features which make it well suited for the proposed program's sub-objectives. Research will follow a multimethod approach utilizing a mix of existing techniques (e.g. geophysics, environmental tracers, remote sensing) and of new cutting-edge methods that will be developed through the program (e.g. thermal imagery, icing monitoring). The proposed research program integrates a unique combination of methods to be applied in a remote but hydrologically important region of Canada. Some of the proposed methods are very innovative and, once developed and tested, will be applicable for other fields of cold region hydrology. The program will provide Northern communities with improved understanding of hydrological processes in alpine glacierized catchments to better anticipate the coming hydrological changes due to climate warming. It will also serve the scientific community providing a new reference research site, and in developing a new generation of hydrological models. Finally, the programs will provide northern research expertise to at least five HQP, who will be prepared to support Canada in facing the adverse impacts of climate change.
随着气候变暖导致山区环境中冰冻圈迅速衰减,它正在导致影响生物多样性,水资源和生态系统服务的重大水文变化。这些不利影响在水源下游数百公里处都可以观察到,因为山区冰冻圈特征(如冰川)是一年中炎热和干旱月份河流的主要水源。 尽管迫切需要制定适应战略,但显然仍然需要对这些水文变化进行可靠的预测。对冰川化流域的水文过程缺乏了解是预测准确性有限的最常见原因。在这种情况下,我提出的研究计划的长期目标是提高对高山冰川流域水文过程的理解,以提高对未来水资源变化的可靠预测。 提出了五个分目标,三个侧重于研究流域的规模:(一)量化的贡献和过程,控制流域流出的功能,如岩石冰川,碎片覆盖的冰,和结冰;(二)表征这些功能,地下水和地表径流之间的相互联系;和(三)表征其对气候变化的敏感性。有两个次级目标侧重于区域范围:㈣测量和相互比较多个流域的这些特征的范围和演变; ㈤编写一份关于冰冻圈-水文相互作用的区域概览。 我的研究项目将集中在育空地区西南部的圣伊莱亚斯山脉,研究地点将是灰熊溪,一个32平方公里的冰川流域,位于克卢恩国家公园和保护区。该研究地点有许多相互关联的冰冻圈特征,使其非常适合拟议方案的次级目标。研究工作将采用多种方法,综合利用现有技术(如物理学、环境示踪剂、遥感)和将通过该方案开发的新的尖端方法(如热成像、结冰监测)。 拟议的研究计划集成了一个独特的方法组合,将在加拿大的一个偏远但水文重要地区应用。一些建议的方法是非常创新的,一旦开发和测试,将适用于寒区水文的其他领域。该计划将使北方社区更好地了解高山冰川集水区的水文过程,以更好地预测气候变暖导致的水文变化。它还将为科学界提供一个新的参考研究地点,并开发新一代水文模型。最后,这些计划将向至少五名HQP提供北方研究专业知识,他们将准备支持加拿大应对气候变化的不利影响。
