Abstract: This research intends to expand the irrigation area by taking advantages of extreme rainfall. The methodology consists of determining the consumptive use of crop, rainfall day and the probability of event, rainfall that is used for cropping, consumptive use of crop when there is happened the extreme rainfall on climate anomaly, and cropping area. To be believed that rainfall that is dropped when positive SOI and negative dipole on climate anomaly will be more than the general rainfall on the same month. The rainfall that is dropped in the catchment area gives the effect to the reservoir inflow and that is dropped in the agricultural area will give the effect to the irrigation water supply. The result shows that the difference between water demand in the normal year and in the climate anomaly period can be used to expand the cropping area.
