| Climate change mainly due to the increase of green house gases cause different patterns of water cycle within the basin. However, it is common that current planning and management practices do not consider the effect of the climate change. So, this study evaluated the effect of climate change on the water circulation within the watershed. This study used several GCM simulations for the double $CO_2$condition for the generation of temperature and rainfall series using the Markov chain. Daily runoff series for 100 years were generated using a rainfall-runoff model. As results. annual temperature increase by £«3.2 ¡£«4.6$^{circ}C$, annual precipitation change £7 ¡ £«8 %, annual runoff change £14 ¡ £«7 %, and potential evapotranspiration amount change £«3 ¡£«4 % for the change of 1 $^{circ}C$ are found to be expected depending on GCM simulations. Even though the simulation results are very dependent on the GCM predictions considered, overall variability of runoff is expected to become higher than the current state. |
