USGS - Harvey Gaged Streamflow Timeseries

This resource provides datasets for stream discharge (flow rate) in cubic feet per second, and gage height (stream depth) from 924 active USGS gages in the Hurricane Harvey impact zone across Texas, Louisiana, Mississippi and Arkansas (see shapefile for all gages).

These data were obtained from the USGS National Water Information System (NWIS) [1] using R scripts provided here. When running these R scripts, 745 of the 924 gages had gage height values, and 577 of the 924 had discharge values. For help in using these R scripts, USGS used to provide support tools but the links for those no longer work. I used R Studio on Windows for these retrievals.

Formats provided:
- Shapefile and csv for gage locations, including link to USGS gage details [1]
- Tabular (csv) datasets for timeseries of water discharge (flow rate) in cubic ft/sec, and timeseries of gage height in ft.
- R scripts to download timeseries data from NWIS

本资源提供了德克萨斯州、路易斯安那州、密西西比州和阿肯色州遭受哈维飓风影响区域924个活跃的美国地质调查局（USGS）测流站点的流量（每秒立方英尺）和水位（河深）数据集。这些数据通过本处提供的R脚本从美国地质调查局国家水信息系统（NWIS）[1]获取。在运行这些R脚本时，924个测流站点中有745个提供了水位值，577个提供了流量值。对于R脚本的使用帮助，USGS曾提供支持工具，但相关的链接现已失效。我在Windows系统上使用R Studio进行了这些检索。

提供的数据格式包括：
- 测流站位置形状文件（shapefile）和csv文件，其中包含USGS测流站详情的链接[1]
- 表格（csv）格式的数据集，包括每秒立方英尺的流量时间序列数据和每英尺的水位时间序列数据
- 用于从NWIS下载时间序列数据的R脚本
