Hydraflow Express in Civil 3D can be used for inlet design and analysis, helping engineers:br br 1. Analyze inlet hydraulics: Calculate water flow, capture efficiency, and head loss.br 2. Design inlets: Determine optimal inlet size, type, and placement.br 3. Evaluate inlet capacity: Ensure inlets can handle stormwater runoff.br br Hydraflow Express simplifies inlet design and analysis, enabling engineers to:br br 1. Optimize inlet design for efficient stormwater collectionbr 2. Minimize clogging risksbr 3.
