| description | Iran is located in semi-arid region and its annual rainfall average is about one-third of the world's rainfall. In recent decades, in addition to population growth, increasing global temperatures led to wide variations in the earth's surface and has resulted changes to the time and place of precipitation. According to close relationship between the hydrological cycle and climate system, any change in climate elements such as precipitation, can have an important impact on the availability of water. The purpose of this research is investigate effects of climate change on spatial and temporal variations of water supply in Tasoj basin by using of HADCM3 model results. In this regard, was used from down scaling data of A2 scenario and then recharge for the period 2030-2013 was predicted by HELP3 hydrological model. The results showed that amount recharge of groundwater in this basin is fluctuating from 12 to 67 mm per year under the A2 scenario. In the future, the western region of the study area will be lower recharge than in other parts of the basin. The reason will be the combined effects of geological and climatic factors. Because of the fine-grained sediments along temperature, evaporation increase and reduced precipitation will be effective in reducing the recharge of this region. Also cross-correlation between precipitation and groundwater recharge showed that southern half of the basin than the northern half will responded in a shorter time period to precipitation changes. |
