Abstract

This paper is dealing with the assessment of climate change scenarios on selected meteorological variables at the Lake Karla watershed, central Greece and it is a contribution to the "HYDROMENTOR" research project. A statistical downscaling method has been employed to estimate monthly precipitation and temperature time series for future climate periods. The outputs of the Canadian Centre for Climate Modeling Analysis Global Circulation Model CGCM3 were applied for three socioeconomic scenarios, namely SRES B 1, SRES A 1B and SRES A2 for the assessment of climate change impact on precipitation and temperature. The methodology has been developed for the historical period 1980-2000 and applied for two future periods 2030-2050 and 2080-2100. Historical and future periods were compared for monthly and annual basis using various statistical criteria such as the mean and standard deviation. Results showed that climate change will have minor impacts on precipitation and even smaller impacts on temperature. [ABSTRACT FROM AUTHOR]

Abstract

Dojran Lake is the smallest natural lake in Macedonia, but is very important water resource for population in the region. Main economy in the region is tourism and fishery. Dojran Lake with its hydrological basin is a closed hydrological system with natural inflow of water to the lake, but no natural outflow. Recharge of the lake is from direct surface and underground inflow. In the period 1988-2000, the water level in the lake continuously was declining. Water level declination caused ecological catastrophe for the flora and fauna in the lake and lake's basin. In 2002, the Republic of Macedonia finished a project to build a system for bringing water from Gjavato wells near Vardar River with capacity of 1 m /s. The water level in the lake has recently increased. The reasons for changing the water level in the lake are not clearly identified, and they are located in hydrological conditions or uncontrolled usage the water from the lake. In order to define the causes of changes in the lake requires detailed hydrological and meteorological analysis. This paper will present the results of mathematical-statistical analysis on the basis of historical data of measured water level, precipitation, and air temperature from hydro-meteorological stationNew Dojran for the period 1961-2008.
