Conclusion• From the results of the analysis, can be in the know that the effects of
changes in temperature and rainfall effect on increasing evapotranspiration. The more the temperature rises then evapotranspiration ride. While the rainfall showed that promote increased rainfall runoff and discharge the year higher. So also with the increasing population and the need for increased water shortages caused high water in april to october. the general impact of climate change did not affect the availability of water, but with the increase in population and water demand increases, greatly affects the availability of water in Kupang city
• with the results of the analysis increased runoff and discharge in the watershed since the year 2013 to 2099. the increasing number of people each year, the need for water also increased, by using water demand scenarios of low, medium and high, combined with climate change scenarios, the analysis of the results indicated that the availability of water is more and reached 593.98 m3/second, but in April-October there is a shortage of water to -49 m3/second. This is due to the high water demand and population increase.
