PRESENTATIONONCONTOURS AND ITS USES

CONTOUR-: An imaginary line on the ground surface joining the equal elevation is known as contour.

BASIC DEFINATION OF CONTOUR

Contour Map is used in order to select the most economical and suitable sites.

USES OF CONTOUR

It helps to locate the alignments of the canals so that it can follow a ridge line.

It helps to mark the alignments of roads and railways so that the quantity of earthwork both in cutting and filling should be minimum.

It helps for getting the information about the ground whether it is flat, undulating or mountainous.

It helps to find the capacity of reservoir and volume of earthwork especially in mountainous region.

It helps us to trace out the given grade of the particular route.

It helps us to locate the physical features of the ground such as pond depression, steep or small slopes.

So by this it is clear that the contouring and contour map plays a vital role in for any types of engineering work. So it is important for us to gain more knowledge in this field so as to serve in coming future.
