In Thailand, Miramar and Vietnam, the capital cities are all located on the river deltas. What am I happened to the location of those cities of the river deltas remove somehow? why?

If the location of the capital cities on the river deltas was somehow removed, it would have a significant impact on the economies and cultures of those countries. River deltas are typically fertile areas that support agriculture and provide important transportation routes for trade and commerce. Additionally, these cities often have access to abundant water resources for drinking, sanitation, and industry.

If the capital cities were no longer located on the river deltas, it would likely disrupt the agricultural production and economic activities in those areas. The cities may struggle to access the necessary resources for their populations, leading to food shortages, water scarcity, and economic instability. The cultural identity of the cities may also be affected, as the rivers are often integral to the history and traditions of these areas.

Overall, the removal of the capital cities from the river deltas would have far-reaching consequences for the countries as a whole and could potentially lead to social, economic, and environmental challenges.
