Longitudinal Streamflow in Headwater Streams on Prospect Hill Tract at Harvard Forest 2003

We have initiated long-term monitoring of streamflow in headwater streams on the Prospect Hill Tract at the Harvard Forest. In addition, we have periodically recorded summer flow conditions longitudinally along the length of headwaters within Harvard Forest to obtain information about spatial heterogeneity of flow and of availability of aquatic habitat within these headwaters. In summer of 2003, we recorded streamflow each week at 20-m intervals along the length of two tributaries of Nelson Brook, Tributary A, from Route 32 to its outlet from the Black Gum Swamp, and Tributary B, from its junction with Tributary A to its origin in wetlands north of Prospect Hill Road.

我们已启动对哈佛森林（Harvard Forest）展望山地块（Prospect Hill Tract）内源头溪流（headwater streams）的长期径流（streamflow）监测工作。此外，我们还定期对哈佛森林内源头溪流的夏季径流状况进行沿程记录，以获取这些源头溪流的径流空间异质性（spatial heterogeneity）以及水生栖息地（aquatic habitat）可利用性相关信息。2003年夏季，我们沿纳尔逊溪（Nelson Brook）的两条支流开展每周一次的径流监测，监测间距为20米：支流A的监测范围为从32号公路（Route 32）至其在黑胶树沼泽（Black Gum Swamp）的出水口；支流B的监测范围为从其与支流A的交汇处至其在展望山公路（Prospect Hill Road）北侧湿地的源头。
