LONG-TERM TRENDS OF GROUNDWATER RUNOFF CHANGES OF THE VOLYN POLISSIA RIVERS (UKRAINE)
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2013, Vol 456, Issue 456
Abstract
In this study the contribution of individual sources of river flow Volyn Polissia (Ukraine) by base flow separation techniques for two specific periods: 1961–1990, and 1991–2010, the multiplicity of 1961–1990 was considered as representative to obtain reliable values climate standards. The calculations indicate significant changes in the structure of river outflow. The share of power in the downstream river snow fell from 47 to 28%, and has increased the role of groundwater. Average annual runoff into rivers Polesie groundwater runoff in the Volyn Ukraine for the period 1961–1990 was approximately 38% of the total outflow. Today (1990–2010 onwards) component supply groundwater runoff rose about 1.4 times and is 53%.
