Short summary
Daily rainfall data in five stations Northern Tunisia used to detect the trend and non-stationarity of dry spells. The irregular distribution of rainfall in the growing season for Sidi Abdelbasset station has increased the number of dry spells. The increase of rainy days in Ghézala dam and Sidi Salem stations resulted in a decrease of dry spells in this area. For one year (wet season) return period, dry events occurred from 14 to 27 days constitute an agricultural potential risk for the zone.
