The single-event OTTHYMO model can be converted to continuous OTTHYMO model to run continuous simulation. To do this, first create a Continuous OTTHYMO project using menu File -> New Project -> New Continuous Otthymo Project.
Then the single-event model can be imported to the Continuous project using the menu File -> Import -> Import VH Scenario (Current Project). Extra parameters (e.g. land cover and soil parameters) are added to hydrologic objects to enable continuous simulation.
