Importance to Bangkok

Flooding and Water Management

The Chao Phraya River basin is prone to flooding, particularly during the monsoon season.

The Thai government has implemented various flood management and control measures over the years to mitigate the impact of floods on Bangkok and surrounding areas.

Environmental Concerns

Like many significant rivers worldwide, the Chao Phraya faces environmental challenges, including pollution and erosion.

Efforts are being made to address these issues and promote sustainable management of the river’s resources.
