Annual Mean Precipitation in the Sana River

Abstract

The paper deals with the annual mean amounts, the intensity and the probability of precipitation in the drainage area of the river Sana (in the northwestern part of Bosnia and Herzegovina). Generally, the Sana drainage area is a humid region. Thus, the annual precipitation measured in most of the meteorological stations clearly shows two maximums – in November and in June. Almost every station included in the research shows a continental pluviometric pattern, while more significant maritime influence is shown in the stations positioned in the west, the southeast and the south of the researched area. The monthly fluctuations in precipitation are considerable. The precipitation are most likely to occur during summer and spring, while the annual intensity of precipitation in nine considered stations is 8.06 l/m2.
