A dam blocks the natural flow of a river 🌊, causing water to collect and form a reservoir 🏞️. This flooding reshapes the river’s original course and alters the surrounding landforms 🌍. Downstream, reduced water flow can narrow the river, change sediment movement 🪨, and gradually transform the landscape over time. These long-term effects can significantly reshape the river’s natural topography and ecosystem 🌱. Credit: Emriver . .
