SMOFlow is a Ruby hydraulic modeling library developed by Sebastian Madrid Ontiveros. It aims to fill the gap in hydraulic modeling libraries within the Ruby ecosystem. Built for hydraulic modellers, it provides runoff and flow calculation capabilities for sub-catchments, and can be used for roads, roofs, permeable areas, sewage flows, trade flow, and similar scenarios.
Based on the collected information, SMOFlow’s core methods include the Rational Method and timestep-based calculations. It emphasizes being “developer-friendly,” meaning developers can use it as a Ruby gem to perform transparent calculations, run quality checks, and understand how different surface or flow components contribute to total outflow. For engineering review, internal tool development, or teaching demonstrations, this kind of explainability can be more valuable than black-box software.
The project explicitly supports Ruby, can be installed via gem install smo_flow, and provides links to RubyGems and GitHub. The available text does not mention Rails, Python, JavaScript, or other SDKs, nor does it describe integrations with GIS, SWMM, CAD, or commercial drainage software. Since it is a local Ruby library rather than a SaaS product, it can naturally run in the user’s own development or server environment.
The page provides GitHub and Buy Me a Coffee links, suggesting it leans more toward an open-source/community project model. However, the collected text does not directly list a license, so the specific open-source license cannot be confirmed. No commercial subscription, enterprise edition, or usage-based pricing information was found. The main cost is likely the user’s own integration and validation effort.
Its strengths are a clear focus, simple installation, and attention to a hydraulic modeling need that is relatively uncommon in the Ruby ecosystem. Its limitations are limited public information: no complete API examples, maintenance frequency, test coverage, engineering case studies, or license details were found. It is suitable for hydraulic/drainage modellers building engineering calculation tools in Ruby, as well as developers who want transparent validation of flow components. If you need a mature GUI, regulatory reporting templates, or a large-scale modeling ecosystem, you may still need to use it alongside professional software.
The available text does not provide information about access from mainland China, mirrors, payment options, or network availability. Access stability for RubyGems and GitHub in China may depend on the network environment, but this cannot be determined from the text alone, so it should be considered unknown. Possible alternatives include EPA SWMM, Python hydrology/hydraulic calculation libraries, or commercial drainage modeling software.
