| In this study, the drought indicator is calculate from the rainfall, daily highest temperature, streamflow and Palmer Drought Severity Index(PDSI) for water plan and drought management in a relatively wide region. Three levels of drought severity, called drought watch, drought warning, and drought emergency, are established for these series which determine exceedance levels. The 25% nonexceedance level is used for drought watch, 10% for drought warning, and 5% for drought emergency to figure how well the drought indicators represent the past-drought and that those can be used for drought monitoring. As a result, 9-month and 12-month precipitation, and PDSI series shows the best consistency and high correlation indicate droughts. Because the results are based on the gauged data and simply calculated, the suggested indices can be used for basic data for drought monitoring system of a basin. |
