The stream gradient, also known as the slope of a stream, can be calculated by measuring the vertical drop of the stream over a certain distance. It is expressed as the change in elevation divided by the length of the horizontal distance. The formula for calculating stream gradient is: Stream Gradient = (Change in Elevation) / (Length of Horizontal Distance) This can be measured using a surveying or topographic map, or by using a GPS or altimeter to determine the elevation at different points along the stream.«A soil chronosequence study on terraces of the catawba rivernear charlotte, nc: insights into the long-term evolution of amajor atlantic piedmont drainage basin»
