The Darkosh records show a minimal, though statistically significant, negative trend (Figure 6). From Darkosh onwards, if not before, the Orontes can be considered a regulated river. Despite data gaps, the latter shows a quite regular variability,'8with drier and wetter periods compared to the mean, and no extreme drought or flood periods (Figure 6). Generally, the downstream station Jisr al Shughur (15,130 km2) exhibits a high-flow season from December to May and a low-flow season from June to November.
