See how water became infrastructureExplain how barrages, canals, and settlements turn a distributary into a managed water system.Damietta is a river channel embedded in infrastructure built for irrigation, navigation, and settlement.
Follow the branch through historyConnect the branch's geography to Damietta, Mansoura, Ras El-Bar, and the Crusades.A river mouth can be a port, a crossing, a military gateway, and a coastal landscape at once.
Notice a delta under pressureRelate lagoons, sediment supply, subsidence, and coastal change to the modern delta.The delta remains green while reduced sediment supply and coastal processes make its margin more vulnerable.
