OpenFlows Storm 2026: Stormwater Modeling Software

OpenFlows Storm 2026 is Bentley's next-generation stormwater modeling software, replacing the legacy StormCAD product . It delivers advanced storm sewer design, detention pond modeling, and real-time control simulation in a unified platform .

Key New Features in Storm 2026

Advanced Stormwater Modeling

• Comprehensive System Modeling: Combines storm sewer networks, detention ponds, open channels, and culverts in a single model

• Subcatchment-based Runoff: Simulate rainfall-runoff processes to generate hydrographs from storm events

• Advanced Hydrology Methods: Supports SCS, Green-Ampt, and other infiltration methods for runoff calculation

Dynamic Simulation & Control

• Dynamic Wave Routing: Accurate representation of surcharged flow, flooding, and backwater effects

• Real-Time Control (RTC): Simulate operational rules and active control strategies for detention and diversion structures

• Urban Flooding Analysis: Evaluate system performance under extreme events and identify flood-prone areas
