HydroBOA — Hydraulic Design Anywhere, Cloud Power When You Need It

HydroBOA is a professional engineering app for SWMM, EPANET, and HEC-RAS project workflows that runs in your browser and on mobile devices — with an offline-first design environment and on-demand cloud simulation power.

"Design, edit, analyze, and manage hydraulic models anywhere — even without internet — then use cloud compute for heavy simulations and optimization when required."

🔌 Offline-First Engineering Workspace

Most engineering SaaS stops working without internet. HydroBOA doesn’t.

The core design environment runs locally on your device:

  • Model drafting and editing
  • Profile design and network adjustments
  • GIS terrain and vector tools
  • Git-like version control
  • Document viewing (PDF, CAD, Office files)
  • Reporting and visual outputs
  • Local project storage

You can continue building and refining your model in the field, on site, or in low-connectivity regions.

☁️ Cloud Compute When It Matters

For computationally intensive tasks, HydroBOA uses secure cloud services:

  • Full model simulations
  • Optimization runs (BOA, DE, future PSO)
  • Large-model processing
  • Step-by-step video tutorials built into every module
  • Runs the real SWMM & EPANET engines — not a WebAssembly or JS approximation

Workflow: Design offline → Run cloud simulations → Continue editing locally.

This keeps your device light while still giving access to workstation-level compute when needed.

🔒 Privacy-First Architecture
HydroBOA minimizes unnecessary data transfer.
  • Projects stored locally
  • Version history stored locally
  • GIS processing on-device
  • Usage reports only sent when user chooses

Engineers keep control of project data.

⚡ 90% Faster Preliminary Design
HydroBOA accelerates the engineering work around modeling:
  • Drag-to-edit profiles
  • Side-by-side model comparison
  • Cross-model clash detection
  • Automated reports and visuals
  • Differential BOQs
  • Intelligent optimization
