Hydraflow Hydrographs 9.00

Hydraflow Hydrographs by Intelisolve is a specialized stormwater hydrology application designed for civil engineers, hydrologists, and site designers. It streamlines rainfall-runoff analysis, hydrograph generation, and detention/retention basin design, helping users evaluate peak flows, volumes, and routing performance for watersheds and development sites.

Key capabilities include:

• Rainfall-runoff modeling using widely accepted methods such as NRCS (SCS) unit hydrograph and Rational methods
• Detention and retention basin design with stage-storage and stage-discharge calculations
• Outlet structure sizing and evaluation for orifices, weirs, and multi-stage configurations
• Hydrograph creation, combination, and routing through reservoirs and reaches (e.g., level-pool/Modified Puls)
• Support for standard NRCS design storms (Type I, IA, II, III) and custom storm definitions and IDF curves
• Time of concentration tools using common empirical methods
• Infiltration and abstraction options, including Curve Number-based approaches
• Clear, submittal-ready reports with tabular and graphical outputs, plus comparison of pre- and post-development conditions
• Flexible units (U.S. customary and metric) and an intuitive interface for building, editing, and reviewing models

Hydraflow Hydrographs helps teams meet regulatory requirements, compare design alternatives quickly, and document stormwater performance with professional-quality reports.
