Da Nang is the third largest city and one of the three largest ports in Vietnam, and the economic hub of the central region. Hoi An, 30 km to the south in Quang Nam province, is a UNESCO World Heritage site and one of the major tourist destinations in Asia. The Vu Gia – Thu Bon river basin is shared by Da Nang and Quang Nam provinces and drains to the ocean through the cities of Da Nang and Hoi An. Rapid urbanization and population densification along the rivers and in the coastal floodplains of both provinces are intensifying flooding issues in the basin, and particularly in the cities of Da Nang and Hoi An. Because of the proximity of the two cities, flood control measures taken to address flooding in one city will impact the other unless actions are carefully coordinated.
