______________________________________________Gradient Data and Calculation SheetCalculation of River GradientRiver gradient (slope ) is the change in vertical elevation divided by the horizontal distance.This exercise will report the final gradient using metric units of measureoVertical Elevation (EV) in meters (m)oHorizontal Distance (HD) in kilometers (km)Map contour lines (measures of vertical elevation are in feet, so feet must be multiplied by 0.305 tocover the measurement to meters.How to MeasureThe West Austin Quadrangle Map has been marked to show you where the sources of the exampledata and locations where measurements were taken.To make measuring easier the map can be magnified using the controls in the map viewing .Two Methods to measure the horizontal distance along the stream
