Abstract/Summary

Relations between mean annual flood estimates and basin area and precipitation, as well as dimensionless flood frequency curves, have been derived from a number of groups of gauging stations in the southern Caucasus. Total precipitation and its seasonal distribution are extremely variable at this location. The importance of antecedent soil moisture deficit (closely linked to the seasonal distribution of precipitation) in determining the shape of flood frequency curves is discussed through previous empirical studies and recent sensitivity analyses. The varying shape of regional curves from the southern Caucasus is related to the variations in soil moisture deficit
