HydroCAD is a Computer Aided Design tool used by Civil Engineers for modeling stormwater runoff. HydroCAD provides a wide range of commonly used hydrology and hydraulics capabilities including:

• SCS, NRCS, and SBUH runoff hydrology
• Rational Method with automatic IDF curves
• Use local rainfall data or the built-in rainfall library
• Easy management and reporting of multiple rainfall events
• Unlimited hydrograph points
• Hydrograph routing through ponds & reaches
• Coupled ponds with automatic tailwater
• Automatic hydraulics and culvert calculations
• Advanced flow simulations including pumps and float valves
• Progressive dam breach simulations
• Automatic pond storage calculations, including embedded storage chambers
• Automatic layout and modeling of underground storage systems
• Land-use analysis and pollutant loading calculations
• Built-in CAD watershed import
