Increased rainfall can have profound effects on river ecosystems, including flooding and sediment transport. These changes can impact the physical and biological components of the ecosystem. Flooding can disrupt habitats, wash away nests, and alter the flow of nutrients, affecting aquatic life. Moreover, higher water levels can increase the connectivity of habitats, allowing species to migrate and colonize new areas. However, excessive precipitation may lead to nutrient runoff, promoting algal blooms that can deplete oxygen levels and harm aquatic organisms. Thus, understanding rainfall impacts is vital for effective water resource management.
