effects of avulsion on the drainage system of sundarban?

Avulsion in the Sundarbans can significantly alter the drainage system by changing the course of rivers and creating new channels. This process can lead to increased sediment deposition in certain areas, impacting water flow and potentially causing flooding in low-lying regions. Additionally, avulsion can disrupt the delicate balance of freshwater and saline water, affecting local ecosystems and biodiversity. The rapid changes may also hinder traditional practices and livelihoods dependent on the region's water management.
