The tool computes normal-depth rating curves for various shapes like rectangular, trapezoidal, triangular, and compound gutters.
The Hydraflow Express Extension is typically as part of the AutoCAD Civil 3D installation.
The Hydraflow Express Extension addresses a wide variety of hydraulic and hydrologic tasks using a streamlined, grid-based input system. The tool computes normal-depth rating curves for various
It calculates hydraulics for six different inlet types, including curb, grate, and slotted inlets, adhering to standard HEC-22 methodology.
Engineers can model and design culverts with circular, box, elliptical, and arch shapes. It supports computations for hydraulic grade lines (HGL) across various flow regimes, including roadway overtopping and hydraulic jumps. It calculates hydraulics for six different inlet types,
For modern versions, extensions can be downloaded directly from your Autodesk Account under the "Extensions" or "Plug-ins" category for your specific Civil 3D version. Integration and Workflow
Users can compute runoff hydrographs using SCS, Rational, and Modified Rational methods. It also helps estimate required detention storage for pond sizing. For modern versions, extensions can be downloaded directly
The is a powerful hydrology and hydraulics toolkit designed to provide civil engineers with fast, reliable calculators for common stormwater tasks directly within their design environment. Rather than building complex network models, this extension allows for rapid preliminary design and quality assurance checks through a simplified user interface. Key Capabilities and Features
