Upstream-downstream flow regime alteration
Summary
The study assesses the impact of dam operations and climate change on the Mond River and its downstream estuary. While dams cause 'drastic' to 'severe' flow alterations in the river corridor, remote sensing indicates that climate change factors—specifically sea-level rise in the Persian Gulf and meteorological drought—have a more significant impact on the Mond-Protected Area than upstream river regulation or land-use change.
Key insights
- Dam operations on the Mond River cause significant flow alterations, though the intensity decreases downstream. The impact is 'drastic' below the Tangab and Salman Farsi dams, with River Impact (RI) values of 0.02 and 0.08 respectively, but reduces to a 'severe' impact (RI value of 0.35) at the Ghantareh gauge due to additional flow from a mid-basin area of approximately 20,254 km2.
- Climate change drivers, including sea-level rise in the Persian Gulf and meteorological drought (as indicated by the standardized precipitation index), exert a greater influence on the Mond-Protected Area than upstream river regulation or land-use changes. Sea-level rise has led to the inundation of coastal areas and a landward shift in vegetation.
