Coastal Geology and Shoreline Formation

The Gold Coast of South District, Tainan City, stretches along a gently curving arc of sandy shoreline shaped by centuries of fluvial and marine interaction. Sediment carried by the Zengwen River and smaller coastal streams is deposited here, gradually forming broad beaches backed by low dunes. These quartz-rich sands, with a golden hue under the afternoon sun, owe their coloration to a mixture of fine mineral grains and shell fragments ground smooth by wave action. Offshore sandbars act as natural breakwaters, dissipating wave energy and creating calmer inshore waters ideal for swimming and fishing.
