Obviously rivers must flow downhill. The type of terrain it flows through will always vary. The river is always at its steepest descent in mountainous areas, and of course, that's where the rainfall is highest.

The Rhine River has a moderate gradient, which varies along its course. In its upper reaches, particularly in the Swiss Alps, the gradient is steeper, leading to faster-flowing waters, while in the middle and lower stretches, the gradient becomes gentler, resulting in a slower flow. Overall, this gradient contributes to the river's navigability and its role as a major transportation route in Europe.
The average gradient of the Missouri River from its source to its mouth is approximately 0.2 feet per mile. This gradual slope reflects the river's extensive length of about 2,341 miles, which allows for a very low gradient overall. Variations in gradient can occur along different sections of the river, but the average remains relatively low due to the river's course through diverse terrains.
Take the elevation from an upstream point on the river and the elevation from a point downstream on the river. Calculate the difference in the two elevations. Measure the distance between the two points by tracing the path of the river. Divide the difference in the two elevations by the distance between the two points in order to get the slope of the river, or the river gradient.
If a river channel has a steep gradient, the river flows faster and has more erosive energy.
A pressure difference is also known as a pressure gradient.
The upper course of a river is characterized by steep gradients, fast-flowing water, and features such as waterfalls and rapids, typically found in mountainous or hilly regions. In contrast, the lower course has a gentler gradient, slower-moving water, and broader floodplains, often exhibiting meanders and deltas as it approaches its mouth. The upper course primarily focuses on erosion and sediment transport, while the lower course is more about sediment deposition and shaping the landscape.
A river beginning high up in the mountains will fall sharply until the gradient levels out in the valleys. A river beginning in lower hills will naturally have a less steep gradient over all. Therefore, each river's longitudinal gradient will be different and there is no definitive answer.
The gradient of a river is the steepness of its slope.
A 'Rejuvenated' river is a river with a gradient that is raised by tectonic uplift.
