What is contour in civil engineering?
Answer:
A contour is a line on a topographic map that joins all points of the same elevation (height above sea level). Each contour line is continuous, it joins itself.
If you look down vertically on a perfect cone that is 4 cm high sitting on a table the 1 cm contours for this shape would consist of 4 concentric circles ( one inside the other evenly spaced) and a dot to represent the tip of the cone. The largest circle would be the 'zero' contour, the base of the cone resting on the table.(sea level if it was a perfectly shaped volcano in the ocean).The next smaller circle would be the 1cm contour, this is the line that joins all points on the cone that are exactly 1 cm above the table surface. The next smaller circle will be the 2cm contour. The dot will be in the center of all the circles and represents the 4cm contour or the exact tip of the cone.
Civil engineers are famous for moving earth (to build highways and railways, etc.) Contours describe on a map the ups and downs of the land and good engineering requires that cuts and fills (removing high spots to fill low spots) be minimized to save time and money. Moving earth is very expensive.
Actually contour is a topographic map. The topographic map is a detailled and accurate graphic representation of cultural and natural features of the ground.It has multiple uses in the present day.e.g
#any type of geographic planning or large scale architecture
#earth science and many other disciplines.
#mining and other earth based endeavours.
#recreational uses such as hiking.
#orienteering. etc.
A contour line shows elevation in the map.
