Retention Ponds Modeling with OpenFlows PondPack - AulaGEO

Welcome to this comprehensive course on Stormwater Modeling, Detention Pond Design, and Hydrologic Analysis using OpenFlows PondPack, developed under a Digital Twin–aligned approach for modern drainage and water infrastructure engineering.

This course is designed to take you from the fundamentals of PondPack to the development of complete stormwater modeling workflows for detention and retention systems. Through a structured, hands-on approach, you will learn how to define rainfall events, build watershed networks, configure scenarios, estimate storage requirements, design outlet structures, and perform routing analyses using one of Bentley’s most practical hydrologic tools.

Unlike courses that focus only on software commands, this training emphasizes engineering reasoning, scenario-based analysis, and model interpretation. You will not only learn where to click, but also how to understand runoff behavior, compare predevelopment and postdevelopment conditions, and evaluate whether a detention system performs according to design objectives.

In addition, this course introduces a Digital Twin perspective, where stormwater models are not treated as isolated calculations, but as structured digital representations of drainage assets and watershed behavior. In this context, PondPack becomes a practical tool for simulating design alternatives, testing performance under multiple storm events, and supporting better infrastructure planning and decision-making.
