Title : THE INFLUENCE OF CLIMATE CHANGE ON WATER REGIME IN DRAINAGE LAND
Abstract : The terrestrial water cycle and the impact of climate change have an important influence on water resources and on the potential for flood or drought and are, consequently, crucial to both agricultural and natural ecosystems. Soil properties and water regime can be improved in various ways, depending on soil texture and climatic conditions. Drainage hydrologic performance often depends on the quality of the installation, anthropogenic and climatic factors. It is important to assess the functioning of the drainage at different weather conditions. Under climate change the impacts of high temperatures, altered patterns of precipitation, increased water demand, and increased frequency of extreme events such as drought and floods. It is forecasted that air temperature will be subject to very high growth in Lithuania in the twenty first century. Especially significant changes are expected in winter. Climate conditions and physical geographic factors determine the fact that there are 3.4 million hectares of too wet lands in Lithuania, or approximately 86% of the total agricultural area, the intensive and productive usage of which is possible only after drainage. The analysis of four decades revealed a statistically significant trend of increase of annual temperature during spring season. A statistically significant trend of increase of annual drainage runoff was found during winter season, while there is no statistically significant trend for annual precipitation, the trend is very slightly increasing. The analysis of change trends of drainage runoff during different months revealed statistically significant changes in all winter months – there is a trend to increase.
