Abstract
The Reak watershed is one of the 52 Utility Watershed ini Lombok River Basin. The level of Water users in Reak Watershed is quite large, aside from the use of irrigation, drinking water, and the need for non-consumtive use. The Reak watershed has a watershed area of 37.81 km2. Thies type of river is Intermitten. Hydrological analysis is used to select influential rainfall stations using the Thiesen polygon. Then collect rain station data that has influenced the last 20 years. Calculate the generation of discharge data using average.Potential daily month evapotranspiration analysis was obtained from the evaporation data of the ishoyet area from the evaporation data for each climate station.Drought analysis uses average data with the method Palmer Drought Severity Index (PDSI). Based on the results of the Thiessen polygon, it is found that the Rainfall in the Reak Watershed is Influenced by the Santong Rainfall Station which is also located in North Lombok Regency.At the Water Holding Capacity (WHC), it is found that the Sto in the Reak River Basin is 156 mm. In the Palmer Drought Severity Index Analysis, it is found that Jan to May is a wet month, June is a dry month, July to October is extreme dry, November is dry and December is wet.
