You just have to substitute values of slope and vertical distance in formula and get value of horizontal distance. Similarly, any one of them can be found if other two are given. For instance, if you have a slope given in Percentage as 10 % and a vertical distance of 50 feet, then equation will look like:
How to calculate slope from a contour map. Select an area on the map where you want to know the degrees of slope. Find the run or horizontal ground distance. Lay a ruler crossing exactly perpendicular to the contour lines and measure the distance. Convert the distance to metres.Find the rise or vertical distance.Identify the elevation of the first and the last contour line on your line. Subtract one from the other to find the rise in metres.onvert the distance to metres. Find the rise or vertical distance. Identify the elevation of the first and the last contour line on your line.
