Definitions of terms & values

  • drainage: gives the drainage area in square kilometers
  • status: A for active stations and D for discontinued ones
  • regulation: R for stations where the flow is regulated, or N for natural, unregulated ones
  • years: number of years that the station has been in use
  • av. peak flood: the average annual instantaneous peak flood, multiplier is the ratio of Q100 to the average peak flood for this station;
  • Q2/A^0.75: the average peak flood divided by the drainage area raised to the power of 0.75. This formula can be used with the multiplier to get a ball park estimate of Q100 for creeks in the vicinity.
