ABSTRACT
In the light of the climate variations problem leading to many extreme events of weather in Bulgaria, it is important to analyze the relationship between the water resources changes and the precipitation variability leading to change of quality of life in the region in view.
The present paper shows the link between the variation of precipitation characteristics and the water resources changes in Northwest Bulgaria, using range of specific statistical parameters and climate related parameters, informative hydrological characteristics, trends and tendencies.
Data from selected representative meteorological stations were used (in their seasonal and annual aspects), various important applied climatice characteristics (normals, percentiles, values corresponding to different return periods), related to selected hydrological information.
Generally speaking an answer to the following question have been looking for, was a significant change of precipitation leading to a considerable shift of the water resources pattern in Northwest Bulgaria.

Keywords: water resources, precipitation characteristics
