Hydraflow Storm Sewers 12.0

Hydraflow Storm Sewers is a drainage design and analysis application used to plan, size, and validate municipal and site storm sewer networks. It helps civil engineers model pipes, inlets, manholes, and outfalls; evaluate hydraulic performance under design storms; and produce clear reports for reviews and construction documentation.

Key capabilities:

• Build and analyze complete storm drain networks, including inlets, junctions, and outfalls.
• Compute hydraulic and energy grade lines, account for minor and junction losses, and flag surcharging.
• Size pipes and structures automatically to meet target slopes, cover, velocities, and capacity constraints.
• Estimate peak runoff with the Rational method and accept user-defined inflows or hydrographs.
• Perform inlet capture and bypass analysis using industry‑standard methodologies for gutter flow and spread.
• Support common pipe shapes and materials with Manning’s equation and tailwater controls at outfalls.
• Compare scenarios across multiple design storms and return periods.
• Generate tabular reports, profiles, and summaries suitable for submittals and QA/QC.
• Integrate smoothly into typical CAD/GIS-centric civil design workflows via import/export of project data.

This tool is suited for preliminary layout through final design, helping teams demonstrate compliance with local drainage criteria and optimize system performance.
