Status Report: Stream Velocity, Discharge, and Water-Quality Parameters at the Intersection of the San Bernard River and the Gulf Intracoastal Waterway, near Rivers End, Texas, October 2003-September 2005

摘要

In the spring of 2004, the U.S. Geological Survey (USGS) agreed to assist Texas Water Development Board (TWDB) in a study of flow dynamics near the mouth of the San Bernard River. Specifically, the USGS agreed to install and operate multiple gaging stations in and near the lower San Bernard River, proximal to the intersection with the Gulf Intracoastal Waterway (GIWW). Figure 1 shows the study area with the locations of USGS gaging stations. Data collected at each station would consist of water velocity and tidal stage. After installation of monitoring equipment, a 48-hour synoptic survey would be conducted, whereby multiple discharge measurements would be made at each location and velocity-index ratings would be developed. The ratings would then be used to determine discharge at each location for entire study period.
