An Integrated Tracer and Hydrometric Investigation of Hydrologic Flowpaths and Streamflow Generation

该研究的目的是确定和量化在美国潮湿的东北部森林流域的水流产生中重要的水文流道。研究包括对暴雨流和基流的分析，结合水文测量（降雨量、河流流量、地下水位高度和土壤湿度）和使用天然示踪剂(18o、Cl-、和222Rn)，为流生成的可能场景提供多个约束。该研究包括两个组成部分（高地和近水道湿地）的分水岭概念。这项研究产生的关于水文路径的信息和知识对于准确评估和模拟沉积在森林流域的化学品的运输及其在极端降雨条件下的行为至关重要。

The objective of the study is to identify and quantify the hydrologic flowpaths important in streamflow generation on a forested watershed located in the humid Northeast of the United States. Research involves analysis of stormflow and baseflow, combining hydrometric measurements (rainfall, streamflow, water table elevation, and soil moisture) with the use of naturally occurring tracers (18 O, Cl- , and 222Rn) to provide multiple constraints on the possible scenarios for streamflow generation. The study includes a two- component (upland and near-channel wetland) conceptualization of the watershed. The information on and knowledge about hydrologic flowpaths produced by the study will be crucial for accurately assessing and modeling the transport of chemicals deposited on forested watersheds and in their behavior under extreme rainfall conditions.
