- This study presents an analysis of consistent wet periods for further improvement of water resources studies. While previous studies have focused on characterizing dry periods, this study uses tree‐ring reconstructed precipitation to detect the occurrence of wet periods of magnitude larger than what can be achieved from the analysis of the historical precipitation records. Tree‐ring reconstructed precipitation for Madaba region in Jordan that began in 1743 was used. The analysis of the historical precipitation indicated the occurrence of short wet periods (1–4 years). The analysis of the 239 years of the reconstructed precipitation indicated the occurrence of long wet periods (7 years), and wet period magnitude of 551 mm, that is 20% larger than the observed from the analysis of historical precipitation. Furthermore, this study presents theoretical formulation that can be used to estimate the expected number of wet events of desired length that could emerge during the operation period of surface resources.
