The probability of heavy rains and river floods is expected to increase with
time in the Northern Caucasus region. Densely populated areas in the valleys
of small mountainous watersheds already frequently suffer from catastrophic
peak floods caused by intense rains at higher elevations. This study aimed
at assessing the flood characteristics of several small basins in the
piedmont area of the Caucasus Mountains adjacent to the Black Sea coast
including ungauged Cemes River in the Novorossiysk city. The
Deterministic-Stochastic Modelling System which consists of hydrological
model Hydrograph and stochastic weather generator was applied to evaluate
extreme rainfall and runoff characteristics of 1% exceedance probability.
Rainfall intensity is shown to play more significant role than its depth in
formation of extreme flows within the studied region.
