Abstract

The area of irrigated rice fields used by subak in the Unda River Basin is 3,891.89 ha, spread over the Klungkung and Karangasem regencies. Specifically, the study of the discharge downstream of Tukad Unda is in the Unda Dam, the irrigation area is called the Unda Irrigation Area, with a total area of 1,104.89 ha of the Unda Irrigation Area. The population of Denpasar City in 2021 is 981,824 people, Badung Regency 696,850 people, Gianyar Regency 521,215 people and Klungkung Regency 181,989 people, currently trying to fulfill clean water sourced from Tukad Unda water flow.To find out the potential of Tukad Unda downstream in providing clean water, an analysis of its water availability and existing water needs was carried out. Analysis of water availability with 90% reliability in the downstream Tukad Unda river was carried out using frequency analysis based on the type of distribution of discharge data obtained in Tukad Unda. Analysis of domestic and non-domestic water needs from 2020 to 2040 is based on the socio-economic development conditions of the community. From the results of these calculations, an analysis of the water balance is carried out, namely comparing the availability of water with the demand for water, so that the deficit or surplus is known from time to time. The need for clean water in the Sarbagikung area until 2040 is 7,757 m3/s. The planned allocation of water from Estuary of Tukad Unda Reservoir for the Sarbagikung area is 1,400 liters/second, covering 850 liters/second to meet the needs in South Denpasar District, 100 liters/second in South Kuta District, 300 liters/second which will distributed to the Districts of Gianyar and Klungkung at 150 liters/second.
