55. The length and width of concave and convex sides of a landslide is shown in the figure above. The Dilation Index of the landslide is………………

The Dilation Index of a landslide is defined as the width of the convex part (Wx)of the displayed mass divided by the width of the concave part (Wc).

Here, Wx = 70m & Wc = 35

Hence, Dilation Index = 70/35 = 2 (Answer)
