Reservoir, human activity impact Ravi River's surface water availability by fivefold

What does a healthy river look like? For most of us, an obvious answer would involve two aspects: water flowing through a channel and green vegetation along its banks. However, in reality, a river's health depends on several factors, such as how much water flows through it, how water moves through the landscape, how that flow changes with the seasons, how sediment moves downstream, how often it spills into its floodplain and how these processes change with the seasons.
