Build your hydrologic network graphically, by dragging and dropping elements into your schematic.

Use Graphical HEC-1 to perform flood hydrology calculations, from precipitation to runoff to routing.

Precipitation Modeling

• Use gauged rainfall data, standard design rainfall distributions, or synthetic rainfall patterns.
• Enter rainfall distributions, basin areas, infiltration losses, and routing methods easily.
• Convert rainfall to direct runoff using any combination of five different loss methods, including SCS Curve Number, HEC Exponential, Initial and Uniform, Green and Ampt, and Holtan.
• Generate runoff hydrographs using SCS, Clark, Snyder, or a user-defined unit hydrograph method.
• Divert and route hydrographs through natural and man-made reaches and reservoirs.

Output

• View hydrographs at any point in the network, in tabular form or graphically.
• Work with hydrographs on-screen, print them out, or export them to other software programs (spreadsheets, word processors, etc.) via the Windows clipboard.
• Create tabular output files.
• Include watershed schematics in your report.
