ANALYSIS OF WATER CRITICAL LEVEL BASED ON METEOROLOGICAL WATER AVAILABILITY AND DOMESTIC WATER NEEDS.

Determining the value of water demand in the residential sector and the meteorological water availability are the two main objectives of the Karanggeneng watershed's water criticality study. The water balance during a ten-year period in the Karanggeneng watershed is calculated using the water criticality index. The Thornthwaite-Matter meteorological water balance approach, which takes into account regional rainfall, potential evapotranspiration, and Water Holding Capacity (WHC) values, is used to determine water availability values. The population and area have a major impact on the amount of water needed. The critical water index value for the Karanggeneng watershed area will be determined by comparing water availability and demand. The study's findings indicate that in places with dense populations and/or little precipitation, household water is crucial. Due to the influence of monthly rainfall, the value of water availability was at its lowest in 2019 and at its highest in 2014. Every year, the value of the need for water rises in tandem with population growth. According to the water criticality index calculation, the Karanggeneng watershed value was below 75% from 2014 to 2017 and from 2020 to 2022, but in 2018 and 2019, the index value above 100% (extremely critical condition).
