Natural flow refers to the unimpeded movement of water in rivers, streams, and other bodies of water. It is influenced by factors such as terrain, vegetation, and climate. Maintaining natural flow is essential for ecosystems, as it supports aquatic life and helps to regulate water quality. In addition to ecological benefits, natural flow plays a crucial role in flood management and sediment transport. When water flows naturally, it can reduce the risk of flooding by allowing excess water to spread out over floodplains. This process also helps to distribute nutrients and sediments, which are vital for healthy habitats and agriculture.
