Hydrognomon

Hydrognomon is a free software application for the analysis and processing of hydrological data, mainly in the form of time series. Hydrological data analysis consists of time series processing applications, such as time step aggregation and regularization, interpolation, regression analysis and infilling of missing values, consistency tests, data filtering, and graphical and tabular visualization of time series. The program supports also specific hydrological applications, including evapotranspiration modelling, stage-discharge and discharge-sediment discharge analysis, homogeneity tests, water balance methods, and hydrometry.
