Here we provide a short description of an expert system for predicting the ice-jamming power in the area of the Northern Dvina River and a procedure to verify this system. This expert system is based on hydrological and meteorological data for 1991–2016. The data were processed using a machine learning technique and adjacent mathematics, because there is no mathematical model of the ice-jamming process and time series of observations are too short to apply classical statistics. This expert system was developed in 2012; it was adjusted using data from 1991–2010 seasons obtained at hydrological stations. The current investigation involves additional data on 2011–2016 seasons to repeat learning and estimate system quality. The developed system demonstrates a reliable efficiency: the forecast results coincide with observations for all six added seasons (2011–2016). It should be noted that the additional data do not change forecast accuracy, which remained approximately 85%, like in the previous study. All developed software is cross-platform, written with a C++ language, and is implemented as a command line application. This software can be easily adopted to operate as a part of the Northern Dvina River online monitoring service.
