Overview

About

Maintained by Timofey SamsonovFirst published 2022-05-183 releasesCRAN page ↗GitHub ↗

River hydrograph separation and daily runoff time series analysis. Provides various filters to separate baseflow and quickflow. Implements advanced separation technique by Rets et al. (2022) doi:10.1134/S0097807822010146 which involves meteorological data to reveal genetic components of the runoff: ground, rain, thaw and spring (seasonal thaw). High-performance C++17 computation, annually aggregated variables, statistical testing and numerous plotting functions for high-quality visualization.
