I worked on urban rivers and their role in improving urban infrastructure cultural ecosystem services. Today I found an interesting web link (BBC Persian) on how a river transforms the urban landscape.

The images in the link show Isfahan, a big city in central Iran. Due to local water resource management system during drought years, Zayandeh Rood (the main river in the city) flows only a few months annually. Today the river brightened and revitalized the city after a dry season. Looking at people and their faces shows how excited they are. I just thought Zayandeh Rood is the most appropriate name for such an influential river: it means a river that generates and creates, a river that gives life.
