Turning Site Design into Quantifiable Flood Resilience with InfoDrainage and Civil 3D

Early‑stage flood resilience design relies on simplified assumptions, limiting understanding of how site-design decisions influence flood performance. This session will present an InfoDrainage‑led workflow to quantify flood resilience at site scale through coordinated parametric design and hydraulic modeling. The session will show how InfoDrainage, Autodesk Civil 3D, Subassembly Composer, and Dynamo software are used together to drive parametric site design and generate inputs for 1D‑2D flood simulation. Rule‑based design logic enables rapid, repeatable generation of site grading and flood mitigation solutions using Dynamo Player. The resulting BIM‑ready terrain and surface models support scenario testing across exceedance and climate change scenarios.
