  Flood Flows

Version 19.0 - September 2020

This program calculates the flood flow in water basins caused by rainfall, flood routing in rivers and reservoirs. For the calculation of the flood flows in water basins, the Rational method or other empirical formulas may be used. The concentration time is used in the IDF curve to calculate the rainfall intensity. The use of the above formulas is restricted by certain conditions. The program notifies the user in case one or more formulas are out of scope and should not be used. For flood routing in reservoirs the Storage Indicator method is used.


  • Calculates the flood flow in water basins using the rational method or empirical formulas.
  • If the Rational method is used, one of the following formulas may be utilized to calculate the concentration time:
    • Giandotti
    • Kirpich / Kirpich (PA)
    • Federal Aviation Administration
    • Kerby / Hathaway
    • Carter
    • Eagleson
    • Espey / Winslow
    • SCS Lag
    • Length and velocity
    • TR-55U / TR-55P
    • Izzard
    • California Culverts Practice
    • Kinematic Wave
    • Direct value.
  • In the case of empirical formulas, one of the following five options may be used:
    • Fuller
    • Forti
    • Fanning
    • Iskovski
    • Kuichling.
  • For flood routing in a river the following methods may be used:
    • Muskingum
    • Muskingum - Cunge
    • SCS Convex
    • Kinematic Wave.
  • Solve unlimited number of problems simultaneously.
  • Snyder and SCS synthetic hydrographs.
  • Compare multiple formulas using the same set of data.
  • Graphs visually present the results of flood routing in rivers or reservoirs.
  • Import / export data from / to Microsoft Excel or other spreadsheets.
  • A correction factor for areal precipitation may be used when the rational method is applied.
  • The concentration time can be estimated using the well known formulas of Izzard, California Culverts Practice and Kinematic wave.
  • Formatted output to Microsoft Word for professional printouts with minimal user intervention.
  • Theoretical background has been added in the documentation.
  • Multilevel undo and redo.
  • Compatible with all former versions of the program.
  • Professional reports and printouts in Microsoft Word or directly to the printer.
  • Tip of the day.
  • Full user guide.
  • Tutorials.
  • Live Update.
  • English and Greek interface.
