 The HPV model is a user-friendly version of the original HPV model developed by the Swedish Water Agency. It has several features that make it ideal for educational purposes, including an automatic calibration process using a genetic algorithm or a Monte Carlo approach, as well as the ability to run multiple simulations with predefined parameters. The model can also be used to teach different aspects of hydrologic modeling, from basic principles to more advanced topics. A series of exercises is provided to help students learn about the model and its capabilities. This article was authored by Jay Cybert and MJ Pvis.
