Abstract
Intensity–duration–frequency (IDF) curves are among the most demandable information in meteorology, hydrology and engineering water resources design, planning, operation, and management works. This paper suggests their generation based on annual daily maximum rainfall (ADMR) records from Turkey, Ceylanpinar region meteorology stations next to Syrian border. First, available storm rainfall records are used for dimensionless–intensity–duration (DID) curve development, then, the suitable theoretical probability distribution function (PDF) is obtained for the ADMR record series, which provides return periods’ identification for a given set of risk values, and finally, the ADMR data combination with the DID curve results in IDF curve set. The application of the methodology is presented for four stations in the Southeastern Province of Turkey, Ceylanpinar drainage basin, next to the Syrian border. The comparison of the newly developed IDF curves with the available measurement-based IDF curves indicated the validity of the proposed approaches with less than 10% error.
