Hydraflow Express Extension for AutoCAD Civil 3D 2008

Hydraflow Express Extension for AutoCAD Civil 3D 2008 by Intelisolve is a streamlined hydraulic calculator that runs inside the Civil 3D environment to speed up everyday stormwater design and analysis. It helps engineers quickly size and evaluate culverts, open channels, weirs, orifices, inlets, and gutters using widely accepted methods, including HEC-22 practices and the Rational Method for peak flow estimation. Designed for fast iteration and clear documentation, it produces concise, professional reports and supports both U.S. customary and metric units.

Key capabilities:

• Culvert analysis for inlet and outlet control, including headwater and tailwater conditions
• Open-channel flow checks and sizing for trapezoidal and other common sections
• Weir and orifice calculations for control structures
• Inlet, gutter, and spread analysis for roadway drainage
• Rational Method peak flow and time-of-concentration workflows for small drainage areas
• Simple, dialog-driven interface that complements Civil 3D project workflows

With its focused toolset and tight connection to Civil 3D 2008, Hydraflow Express reduces manual calculations, improves consistency, and helps document design decisions efficiently.
