In this study, daily rainfall intensity, monthly and annuall rainfall
variations, determining natural landscape of the environment, are tried to reveal in
the area of Dikili and Bergama. Daily rainfall data during the period of 1950-1995
were used for analiysis. By taking into consideration»different intensity categories,
daily, montly and annual rainfall variations in Dikili and Bergama area, as suitable
for aim, were studied. Separately, the limits of meteorological drought were
determined by using the normalized rainfall data for the stations. To result of
analysis done, what there was some intensity in rainfalls below 25 mm per day in
study area was revealed. Increase of rainfall vanation in the period of June-
September was established, due to the high ration rainfall which is lower than that
of monthly mean and which is more than twice as much as monthly mean. When,in Bergama and Dikili, year by year rainfall variations are studied, it is seen that
there is an decrease in rainfall amount after 1968 and that the very
decrease get stronger after 1989. As a result of this, heavy drought and very
