The variation of the average water flow from the Căliman Mountains.
The variation of the average water flow from the Căliman Mountains.

Summary/Abstract: The variation of river water runoff is a normal phenomenon, given the close link between runoff and atmospheric precipitation, both components of the water balance. The variation of the flow over a period of time can be calculated using several simple and complex indicators, among which the most important are the absolute and relative deviation, the standard deviation (deviation) and the coefficient of variation. In the Căliman Mountains, no analysis of the variation of river water flow has been made so far, this work being the first of its kind. Following this work, it was observed that the variation of water flow from these rivers in the period 1950-2010 depended strongly on the variation of climatic elements (precipitation and temperatures), but also on the characteristics of river basins, both annually and seasonally.
