Calculation of average slope has been based on the analysis of contours represented on Survey of India’s topographical sheet numbered 58 F/7 and 58 F/8 on the scale of 1:50,000. For analysis, the contour map of the study area with an interval of 20m has been divided into grids of 1 km2 each and then the number of contour crossings has been counted along each side of the grid and divided by 4 to get average contour crossing per km. The number of contour cuttings over the diagonal sides are also counted and divided by 2.8 which gives the average contour crossing
diagonally
