    • Non-linear baseflow separation model with parameters and results (ver. 3.0, December 2025)

    Metadata Updated: January 21, 2026

    This data release contains source code for a non-linear baseflow separation model, calibrated values of parameters, and daily time series of the calculated baseflow component of streamflow at selected streamflow gages. Parameter values were determined by calibration of the model. The file 'run_bfs.zip' in the directory 'Nonlinear Baseflow Model Source Code, Functions, and Scripts" has a complete set of model functions, parameters for 11,985 streamflow gages, and a script to run the model. Instructions and software requirements for running the model are described in the file README.txt
