Walker Branch Watershed: Weekly Stream Water Chemistry

This data set reports weekly stream water chemistry in the West and East Forks of Walker Branch Watershed (WBW). The long-term Walker Branch stream chemistry monitoring is intended to provide data on watershed output of chemicals via streamflow and long-term changes in stream chemical composition. This data set contains two data files of stream water chemistry collected at weekly time intervals from 1989 through 2013. Weekly sampling of stream water started in 1989 in the West Fork and in 1995 in the East Fork. Measured parameters include water level at the weir and stream discharge, water temperature, specific conductivity, pH, alkalinity, and dissolved organic carbon (DOC), soluble reactive phosphorus (SRP), total dissolved phosphorus (TDP), ammonium-N, nitrate+nitrite-N, total dissolved nitrogen (TDN), anion (chloride and sulfate), and cation and trace metal (calcium, magnesium, sodium, potassium, iron, manganese, silicon, aluminum, barium, cadmium, nickel, lead, strontium, zinc, copper, molybdenum) concentrations. The Walker Branch Watershed is located on the U.S. Department of Energy's Oak Ridge Reservation in eastern Tennessee.

本数据集收录了沃克分支流域（Walker Branch Watershed, WBW）东西两支流的每周溪流水文化学监测数据。长期开展的沃克分支溪流水文化学监测工作，旨在获取流域通过径流输出的化学物质数据，以及溪流化学组成的长期变化特征。本数据集包含两份采集于1989年至2013年间的周度溪流水文化学数据文件：西支流的周度水样监测始于1989年，东支流则于1995年启动监测。本次监测的实测参数涵盖堰处水位与溪流流量、水温、比电导率、pH值、碱度、溶解性有机碳（dissolved organic carbon, DOC）、可溶性活性磷（soluble reactive phosphorus, SRP）、总溶解磷（total dissolved phosphorus, TDP）、铵态氮、硝态氮与亚硝态氮总量、总溶解氮（total dissolved nitrogen, TDN）、阴离子（氯化物与硫酸盐），以及各类阳离子与痕量金属（钙、镁、钠、钾、铁、锰、硅、铝、钡、镉、镍、铅、锶、锌、铜、钼）的浓度。沃克分支流域坐落于美国田纳西州东部的美国能源部橡树岭保留地（U.S. Department of Energy's Oak Ridge Reservation）。
