Gibson Jack Idaho 2018 Stream Connectivity Information

This resource includes hydrometric data collected within the Gibson Jack watershed, located in Pocatello, Idaho, USA in the northern Rocky Mountains. These data were collected with the purpose of assessing three-dimensional connectivity in an intermittent stream reach. Stage was measured via Onset U-20 water level loggers at 13 locations within the stream, riparian area, and adjacent hillslopes, and corrected for barometric pressure. For sites within the stream, stage was converted to a hydrograph via a stage-discharge relationship derived from occasional discharge measurements. Discharge measurements were made with a SonTek FlowTracker as well as using dilution gaging methods with an Onset U-24 electrical conductivity logger, which was used to quantify the breakthrough curve for known additions of salt. Local discharge gains and losses in flow along the stream network were calculated using the methods outlined in Payn et al. 2009. Precipitation was measured using a Texas Electronics Rain Gage (0.254mm) recorded by a Campbell Scientific CR1000 datalogger. Temperatures were also recorded at the stream sites using the Hobo U-24 sensors.本数据集涵盖美国爱达荷州波卡特洛市北落基山脉区域内吉布森杰克（Gibson Jack）流域采集的水文监测数据，本次数据采集旨在评估一段间歇河道的三维连通性。研究团队在河道、河岸带及邻近山坡共13个监测点位，通过Onset U-20型水位记录仪（Onset U-20 water level logger）采集水位数据并进行气压校正；针对河道内的监测点位，研究人员基于零星开展的流量监测所建立的水位-流量关系，将水位数据转换为流量过程线。流量监测采用SonTek FlowTracker流速仪，同时结合稀释法测流技术，通过Onset U-24型电导率记录仪（Onset U-24 electrical conductivity logger）量化已知盐分添加量对应的穿透曲线；沿河道网络的流量局部增减量依据Payn等人2009年提出的方法计算。降水数据采用Texas Electronics雨量计（精度0.254mm）采集，并由Campbell Scientific CR1000型数据采集器记录存储，河道监测点位的水温数据则通过Hobo U-24传感器采集记录。
