Velocity profiling at the US Army Corps of Engineers Electric Dispersal Barrier in the Chicago Sanitary and Ship Canal during passage of fully loaded commercial tows: Wall Mounted Channel Master

In 2016, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage. This study included a series of trials in which a tow, consisting of a tug vessel and six fully-loaded barges, transited the EDBS in both upstream-bound (n = 23) and downstream-bound (n = 22) directions. A 600 kHz Teledyne RDI Channel Master Acoustic Doppler Velocity Meter (ADVM), was mounted on the west canal wall at a depth of approximately 5.5 feet (1.7 meters), as measured on August 2, 2016 at 09:15 am CDT. The approximate elevation of the ADVM was 571.2 feet (NAVD88). The wall mounted instrument was located at (41.6423629, -88.060329). The provisional water surface elevation at the USGS streamflow gaging station on the Chicago Sanitary and Ship Canal ranged from 575.81 feet to 577.29 feet over the study period (August 2 to 11, 2016). The ADVM measured horizontal profiles of streamwise and cross-stream components of velocity between the edge of tow transiting the EDBS and the West canal wall for each trial. The ADVM reported velocities at 45 bins spaced by 1.0 meter starting 2.8 meters from the West canal wall. All velocity measurements represent an average of 10 pings, recorded every 10 seconds during measurement, and are included in this data release as Comma Separated Value (CSV) files.

2016年，美国鱼类及野生动物管理局、美国地质调查局与美国陆军工程兵团联合开展了一项大规模跨机构野外研究，旨在探明商业驳船船队对芝加哥卫生与船舶运河（Chicago Sanitary and Ship Canal, CSSC）内电力驱鱼屏障系统（Electric Dispersal Barrier System, EDBS）的鱼类通行阻隔效能的影响。本次研究包含一系列试验：由拖船与6艘满载驳船组成的船队，分别以逆流（n=23）、顺流（n=22）两个方向穿越该电力驱鱼屏障系统。
一台600 kHz的Teledyne RDI Channel Master声学多普勒流速仪（Acoustic Doppler Velocity Meter, ADVM）被安装在运河西壁，其安装深度于2016年8月2日09:15（中部夏令时CDT）测得约为5.5英尺（1.7米）。该仪器的近似高程为571.2英尺（北美垂直基准面1988，NAVD88）。该壁挂式仪器的安装坐标为(41.6423629, -88.060329)。
在本次研究周期（2016年8月2日至11日）内，芝加哥卫生与船舶运河上的美国地质调查局水文测站记录的临时水面高程介于575.81英尺至577.29英尺之间。
该声学多普勒流速仪针对每一次试验，采集了穿越屏障的船队边缘至西壁之间的顺流与横流流速分量的水平剖面数据。仪器以距西壁2.8米处为起始点，沿水平方向布设了45个间距为1.0米的采样仓。所有流速测量值均为10次声波脉冲的平均值，测量期间每10秒记录一次数据，本次公开的数据集以逗号分隔值（Comma Separated Value, CSV）文件格式存储。
