VO5 is the fifth version of the INTERHYMO-OTTHYMO hydrologic model simulation software package. OTTHYMO is a successful hydrologic management model that has been used for various simulation analyses such as: Watershed Studies, Sub-watershed Studies, Master Drainage Plans, Functional Stormwater Management Plans, Site Plans, and Stormwater Management Pond Designs.
Visual OTTHYMO offers single-event and NEW continuous hydrologic modelling to simulate runoff from statistical storm events. The hydrographs generated are based on unit hydrograph theory and can be used for uncalibrated or calibrated modelling studies.

Visual OTTHYMO has been created to provide you with a reliable and dependable model that is straightforward and user-friendly.
Saves you time
Visual OTTHYMO gives users reliable results without a large number of input parameters, giving the model an edge over other “parameter intensive” models. This translates into reduced staff time on your projects.
Reliable & Dependable
Visual OTTHYMO can simulate runoff from statistical storm events. The hydrographs generated are based on unit hydrograph theory and can be used for calibrated or uncalibrated modeling studies.
Visual OTTHYMO has an improved interface that makes the model creation and interpretation of results easier and more efficient than ever.
Visual OTTHYMO is the standard model of choice with many regulatory agencies in Canada, from conservation authorities and municipalities to top consulting firms.
Integrated with an online help system and efficient tech support, the new Visual OTTHYMO Help System will provide invaluable assistance to all levels of user.
