A collection of functions used to parse a flow time series to identify potential periods in which a river system is at baseflow. From there, additional functions can analyze these baseflow events to find baseflow recession rates and run analyses to look for any correlation between baseflow recession rate and flow. Additional functions in this package can estimate active groundwater storage based on the recession coefficient and flow using the HSPF assumptions. Finally, forecasting functions are available to project flow based on a recession decay coefficient. This work is wrapped in a linux workflow within https://github.com/HARPgroup/meta_model/tree/main/models/drought/agws
DEQ Users This package is available for internal distribution on the DEQ Posit Package manager. Additional information on this may be found in the DEQ Methods Encyclopedia. Users will need to add the UAT package manager to their list of secondary repositories: https://positpackagemanager-uat.deq.virginia.gov/DEQmethods/latest. A config file may be provided by the package managers for database integration.

V 0.0.3 July 09, 2026
- Added slope and heteroscedasticity functions.
V 0.0.2 July 09, 2026
- Updated
forwadForecast()withregressionLimitAGWRC()to prevent variable forecasts from dropping below minimum values to prevent extrapolation. Added a method to ensure Q0 is in range as well on lm_constant.
