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 Argonaut SW

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 3,000 kHz SonTek Argonaut SW 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 10 bins spaced by 0.5 meters between 0.57 and 6.07 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（U.S. Fish and Wildlife Service）、美国地质调查局（U.S. Geological Survey）与美国陆军工程兵团（U.S. Army Corps of Engineers）联合开展了一项大型跨机构野外研究，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1艘拖船与6艘满载驳船组成的驳船队分别以上行（n=23）和下行（n=22）方向驶过该电力驱鱼屏障系统。

2016年8月2日上午9点15分（中部夏令时，CDT）测得，一台3000 kHz的SonTek Argonaut SW声学多普勒流速仪（Acoustic Doppler Velocity Meter, ADVM）被安装在运河西岸墙体上，其安装深度约为5.5英尺（1.7米）；该仪器的近似海拔高度为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的美国地质调查局水文测流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场试验，在通过电力驱鱼屏障系统的驳船队边缘与西岸墙体之间的区域，采集沿水流方向与横向的流速分量水平剖面数据。仪器在距离西岸墙体0.57米至6.07米的区间内，以0.5米为间隔设置10个采样仓，并以每10秒采集1次的频率，将10次声脉冲采样的平均值作为单次测量结果。本次公开的数据以逗号分隔值（Comma Separated Value, CSV）格式文件存储，包含所有流速测量数据。
