Correlation between discharge, river Basin surface and rainfall quantity in Kosova

Kosova's surface is quite small (10887 km2), hence its rivers basins and sub-basins have small surface. But even though that surface it's small, there are big differences in rainfall attitudes. The correlation analysis shows that basin surface or rainfall quantity determined water discharge. However, the river basins in this area do not have the same physicalgeographical condition. The main factor of physical-geographical condition is hypsometry, which directly influence the rainfall quantity and river regime. The other characteristic is that hydrographical surface has high commensurable with Kosova's surface. Most of the rivers have autochthon character, except the Iber which spring and flows from Montenegro.In this study the mathematic and statistical methods are used to analyze the hydrometric and meteorological data. The topographic maps are used to calculate the hypsometric storeys. And the basin surfaces are analyzed until the hydrometric stations it covers.
