All-in-One Software

Feature-packed platform to help with hydrologic flow

Single-Event Modelling

Run automated and manual design storms and actual rainfall events for water asset design and model calibration. VO can simulate runoff from statistical storm events. The hydrographs generated are based on unit hydrograph theory and can be used for calibrated or uncalibrated modelling studies.

Continuous Modelling

Seamlessly extend single event models into continuous models to conduct site and natural feature water balance calculations, generate hydrographs for erosion assessments, and more. These reliable results give the model an edge over other “parameter intensive” models, leading to reduced staff time on your projects.

Distributed Rainfall Modelling Technique

Distributed Rainfall Modelling Technique takes data from multiple rain gauges and interpolates to create rainfall “surfaces” and virtual rain gauges, increasing resolution across the study areas. This tool is useful to calibrate models covering large areas with multiple rain gauges.

GIS Capabilities

VO provides a free inbuilt map function that builds a model over an aerial photograph or drainage area plan and calculates model parameters. This increases the efficiency of the model development.

Designed for Water Resource Professionals

Visual Otthymo is the Ideal Tool for Watershed Planning, Design, and Operational Management
