Why does the Rann of Kachchh flood during the rainy season?

The Rann of Kachchh is a bowl-shaped depression that functions as a seasonal marshy salt desert. During the monsoon season, which occurs from June to September, the region fills with water and transforms into a wetland.1

This flooding is driven by the area's geography and climate: as a low-lying, bowl-shaped basin, it collects water from various rivers originating in Gujarat and Rajasthan, as well as drainage from the Luni River. During the subsequent long, hot dry season, this water evaporates, leaving behind a bed of white, salty land.1
