Marun Dam
Marun Dam is a rockfill-earth dam with a clay core. It is 165 metres high from foundation and has a 345-metre crest length.
Strategic and market-access role
Marun Dam matters in the Hormuz Graph as a water and hydropower asset tied to eastern Khuzestan’s Marun-Jarahi basin, where agriculture, urban water demand, electricity generation, and downstream environmental stress overlap. Its role is distinct from Karun and Karkheh dams because it directly affects the Behbahan-side agricultural economy and water conditions in eastern and southeastern Khuzestan. The asset connects river regulation, irrigation exposure, food-production resilience, public utility pressure, hydropower context, and industrial operating risk in a province where water scarcity can quickly become an economic constraint.
Operations, capacity & connectivity
Related use cases
Useful for basin-level water-risk assessment, hydropower context analysis, agricultural supply-chain screening, public-project monitoring, and site-risk evaluation around Behbahan and eastern Khuzestan. Analysts can use it to assess how irrigation allocations and reservoir conditions affect farming, urban services, logistics, and nearby industrial activity. Practical work should verify current reservoir levels, drought exposure, grid role, downstream environmental impacts, and water-allocation rules.
Capacity and service area
Capacity: 150 MW installed hydropower capacity (two 75 MW Francis turbines). Total reservoir volume: 1.25 billion cubic metres. Service area: Behbahan and agricultural land covered by the project’s stated irrigation function.
