Storage-yield dynamics of a rocky mountain valley

山区河流系统及其相关的山谷地下水水库和湿地为地球上六分之一以上的人口和加拿大西部700多万人提供水需求。为了解决山区储水量动态的不确定性，需要进行新的观测，以确定水文过程和控制水从高海拔地区经宽山谷流向邻近低地的生物活动的特征。在这些山谷中，水可以暂时储存在浅层含水层和/或湿地中，这些湿地大多是由海狸创造或维持的。这个研究方案将测量浅水河谷含水层和河谷湿地储水量的大小和变化率。此外，河谷含水层与河流的水文连通性将通过使用水文学、水化学和同位素方法的组合来评估。将实地测量海狸对流经山谷的水流路线的影响。所有的观测都将在位于阿尔伯塔省卡纳纳斯基斯县的西布尔德湖研究盆地进行。这个盆地的水流入弓河，然后流入南萨斯喀彻温河，为农业、工业和城市提供关键的水。利用该设备进行的观测将提供一个改进的科学基础，该基础将整合河流-地下水-湿地的相互作用，并整合生物活动（例如海狸）的影响，以满足当前和未来山区水资源管理和水文建模的挑战。

Mountain riverine systems and their associated valley groundwater reservoirs and wetlands supply the water demands of over one-sixth of the earth's population and over seven million people in western Canada. To address uncertainties in storage-yield dynamics in mountain regions, new observations are needed that characterize the hydrologic processes and biological activities govern the routing of water from higher elevation areas to neighbouring lowlands through wide valleys. In these valleys, water can be temporarily stored in shallow aquifers and/or in wetlands that are mostly created or maintained by beaver. The magnitude and rate of change in storage of shallow valley aquifers and valley wetlands will be measured in this research programme. Also, the hydrologic connectivity of the valley aquifer to the stream will be assessed through using a combination of hydrometric, hydrochemical and isotopic methods. Field-based measurements of the effect of beaver on flow routing through the valley will be made. All observations will take place in the Sibbald Lake Research Basin, located in Kananaskis Country, Alberta. Water from this basin drains into the Bow River and then to the South Saskatchewan River, which provides critical water for agricultural, industrial, and urban use. The observations made with this equipment will provide an improved science base that integrates stream-groundwater-wetland interactions and incorporates effects of biological activities (e.g. beaver) necessary to meet current and future water resource management and hydrologic modeling challenges in mountain regions.
