Abstract
Nowadays, global warming has been a hot issue. Melt water from tropical glaciers in the Andes is used as important water resources and retreat of the glaciers raises risk on the water availability in the future. Therefore water resources management is necessary, and it is important to investigate water balance in the snow-fed and glacier-fed basins in order to understand how much water is coming from snow and glaciers. This study challenges this issue, and the main purpose of the present study is to estimate glacier melt water in Tuni Lake basin, Bolivia which supplies water to the capital area. Because study area is located in high altitude, we could use limited data. From this point the degree-day method may be suitable for estimation of the glacier melt water. However, we need to determine degree day factor in the method. Therefore, we estimated the glacier melt water first by using a water balance method in order to determine degree day factor in the target basin.
