What people say?
I have been using VO for a while now. Modelling with VO is quite helpful and made the job easy. Required tools are within reach and the user interface is very well designed. I like the way it is programmed to run multiple network scenarios and also run multiple simulations with different rainfall data.
Dheeraj ThamatamCivil Projects Manager
Most of my work includes modelling development sites and stormwater management. The model is very easy to model with and to extract the results.
Glenn SwitzerDevelopment Engineer
VO is great. The addition of SWM LID made it a top-notch software for SWM and LID modelling. It is very user-friendly, and it is fast when computing.
Dr. Imtiaz ShahUniversity Professor
VO has allowed me to clearly and accurately model stormwater ponds in Ontario. It is easy to learn with the assistance of the user manual, reference guides, and tutorials. The interface is highly intuitive and easy to get used to. The staff at Smart City Water are quick to respond to requests. As a student in Environmental Engineering, VO has been essential to my research.
Bryn ReynoldsGraduate Student
“[Our] users are Water Resources Engineers and [the] software is used to review digital VO models submitted in support of development applications. As a HYMO users who started off with SWMHYMO, the interface of VO is a lot more user-friendly.
Irina MarouchkoSenior Water Resource Engineer
I had the opportunity to utilize VO OTTHYMO for my thesis project focused on modelling stormwater management ponds and their upstream catchments in Vaughan, Ontario. This software proved to be an indispensable tool for my research, providing robust simulation capabilities that allowed me to accurately predict the hydrologic response of urban catchments to various real-time rainfall events.
VO's intuitive interface and detailed output options made it easy to configure my hydrologic model. The manual also provided very clear and easy-to-follow instructions and descriptions of model components to help me get started on building my very own VO model for the first time.
The project outcomes were pivotal, not only for my academic development but also for contributing practical insights into how stormwater pond design and monitoring may improve in the future.
The technical support provided by the SCW team, helped me to navigate initial learning curves and in successfully implementing my specific research needs. The team’s prompt and professional response to my questions have helped me tremendously.
Jane GaoCarleton University
I’ve been using VO Model for the past eight years, and it has significantly enhanced the efficiency and accuracy of our project outcomes. The software’s intuitive interface allows for easy integration of complex datasets, and its robust modeling capabilities have streamlined our hydrological analyses, saving me valuable time and resources. One achievement was using VO Model to refine our flow simulations for urban creeks in Mississauga, which led to more better-informed decision-making.
The key benefits of VO Model are its user-friendly design, the ability to handle large datasets with ease, and the impressive flexibility in creating customized models. The real-time results and clear visualizations have made it easier to communicate findings to non-technical stakeholders, which is invaluable in my line of work. Additionally, the responsive support team has been extremely helpful whenever I've had questions or needed guidance.
I highly recommend VO Model to anyone in the field of hydrology or water resources engineering. Whether you’re a seasoned professional or new to modeling software, VO Model provides the tools you need to succeed, and I’m confident it will continue to be an essential part of my work moving forward.”
Neelam GuptaManager of Hydrology and Hydraulics
"I have over 26 years of experience in water resources engineering, including stormwater management design for subdivisions and site plans, road reconstruction projects, and hydrologic and hydraulic studies.
VO is my first-choice software for SWM analysis and design.
VO has an easy-to-use interface for constructing a SWM model, including flexibility in the selection of hydrograph types. The ‘drag and drop’ and element connectivity features allows for large and relatively complex models to be constructed easily including flow routing, minor/major flow splits, and LIDs.
I would recommend using VO as an efficient and effective analysis and design tool for SWM applications.”
