The geomorphoclimatic instantaneous unit Hydrograph theory, the joint probability density function of storm duration and intensity, and Philip's representation of the infiltration process are used to derive a flood frequency distribution that could be used in regions with no streamflow records. The resulting flood frequency distribution is in analytical form containing only few climatologic and physiographic parameters of the catchment. This frequency distribution was tested against frequency distributions calculated from historic records for arid and wet climates, with good and reasonable results, respectively.
