  • Chao Phraya Basin (the land drained by the Chao Phraya River itself, and not by its major tributaries)
The mountainous natural boundary of the watershed forms a divide, which has, to some degree, historically isolated Thailand from other Southeast Asian civilizations. In fact, in northern Thailand, the divide roughly corresponds to a long section of the political border of present-day Thailand. Southern portions of the divide's boundary correspond less to the nation's political border, because isolation in this area was prevented by the ease of transportation along the lowlands surrounding the Gulf of Thailand, allowing a unified Thai civilization to extend beoynd the watershed without issue.
