Cantho City is located in the center of the Mekong Delta. It is contiguous to 5 provinces: An Giang on the north, Dong Thap on the north-east, Hau Giang on the south, Kien Giang on the west, and Vinh Long on the east. Cantho has a complex of rivers and canals such as Hau, and Can Tho rivers, Thot Not, O Mon canals. Among them, the Hau Riveris considered a benefactor of this region, since yearly floods deposit large quantities of alluvia to the rice fields. Thank to that Cantho becomes "the green lungs of the Mekong Delta".
