StreamStats is a map based Web application that provides information that can be used by engineers, managers, and planners to make informed decisions on water-related activities. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics. StreamStats allows for the analysis of upstream and downstream relations along streams. In addition, the USGS is currently implementing two simple hydrologic models for Colorado, TR-55 (SCS Curve Number Method) and the Rational Method.
StreamStats currently implements regression equations for estimating instantaneous peak flows for various return flows. It also reports low-flow, flow-duration, and maximum-flow statistics. The current StreamStats “Basin Characterization” tool characterizes the basin for only the parameters that are used in these state-specific regression equations. These current basin characteristics include:
In an effort to better support the hydrologic modeling efforts within the Colorado Department of Transportation (CDOT), the USGS will be adding twenty-seven basin characteristics to the Colorado State StreamStats Basin Characterization tool. The additional basin characteristics will include:
Another addition to the Colorado State StreamStats application will be two simple hydrologic models, TR-55 (SCS Curve Number Method) and the Rational Method. These models will make use of the newly added basin characteristics that are currently under implementation. The addition of the two models is expected to be completed in 2018.
