Meteorological Drought Analysis Using The Theory Of Run Method In Lusi Watershed, Central Java

Reduced water reserves can be caused by decreased rainfall. During the dry season along the Lusi River, Central Java, water quantity decreased, so that the area along the Lusi River passes in drought conditions. This study aims to determine the longest duration of drought and the largest cumulative number of droughts, in the Lusi watershed for a ten-year period. The level of drought in the Lusi watershed was analyzed using the Theory of Run method. The results obtained were the longest drought duration of 9 months and the largest cumulative drought amount of -486 mm and the Lusi watershed was classified as a meteorological drought
