How To Calculate Gradients [Easy To Follow Guide] - THS Concepts

WebAug 7, 2024 · You can calculate a stream's gradient using the following formula: Gradient (in feet per mile) = Drop (in feet) / Length (in miles) For example, if a stream has a drop of 100 feet over a length of 2 miles, its gradient would be 50 feet per mile. A stream's gradient can have a significant impact on its properties and behavior. WebThe degree of meandering of the channel of a river, stream, or other watercourse is measured by its sinuosity. The sinuosity of a watercourse is the ratio of the length of the channel to the straight line down-valley distance. Streams or rivers with a single channel and sinuosities of 1.5 or more are defined as meandering streams or rivers. [1] [3] green day photoshoot
