Synthesis of Water Balance Data from Northern Experimental Watersheds

本研究的重点是汇编北极水平衡研究的现有知识。这将通过1)通过单个站点的调查收集数据，2)综合数据集开发和3)比较分析来完成。本研究将为高纬度盆地建立一个独特的水平衡要素数据库。这些数据将用于比较和了解高纬度流域的水平衡结果，特别强调年际变率、区域变率、各种水文成分（年度和季节）的长期平均值、计算方法和科学框架。将确定北方水文研究中的共同问题，包括优点和缺点，并建议为解决这些共同问题而进行的合作研究努力。这项工作的总体目标是通过对现有国际数据集的综合，促进我们对极地周围水文过程的理解。

This study will focus on compiling existing knowledge from arctic water balance studies. This will be accomplished through 1) data collection through a survey of individual sites, 2) integrated data set development, and 3) comparative analysis. This research will create a unique database of water balance elements for the high latitude basins. The data will be used to compare and understand the water balance results from high latitude watersheds, with special emphasis on inter-annual variability, regional variability, long-term averages of the various hydrologic components (annual and seasonal), methodology for computations and scientific framework. Common issues, both strengths and weaknesses in northern hydrologic studies will be identified and collaborative research efforts to address these common issues will be recommended. The overall goal of this effort is to advance our understanding of circumpolar hydrologic processes through the synthesis of existing international data sets.
