| dc.description.abstract | Drought is a natural disaster that not known beginning and ending. This
research have a purpose to analyze drought index and determine the zoning map
drought index at 15 DAS in East Java 1996-2005 period. Drought index only
observed about hydrological drought using water discharge data as a source
analysis data. The Analysis of drought index using TLM method ( Threshold Level
Method) with HydroOffice software . TLM method is used to determine the value
deficit of water that occurred at 15 DAS samples. Drought occurs when the
duration of water is deficit for 7 days. While, the mapping zonation drought index
using IDW ( Inverse Distance Weighted ) with ArcGIS 10 software. From the
analysis data, the drought index value is nothing impact with the extended DAS
area. The biggest drought index value is 10,76 m

/s in DAS Wonorejo and the
smallest is 0,06 m

DAS 15 samples into 4 regions based interpolation from drought index value.
Zoning map classification drought index that is, 0–2,5 m
