Question
Suppose the area bounded by the water line of a lake the contours 1, 2, 3, 4 and 5 are as follow
Suppose the area bounded by the water line of a lake the contours 1, 2, 3, 4 and 5 are as follows:
A1 = 10,250 sq.m.
A2 = 8, 350 sq.m.
A3 = 7, 750 sq.m.
A4 = 6, 900 sq.m.
As = 5, 250 sq.m.
If the contour interval is 2m., calculate the volume of water in the lake in gallons using the
following:
a.End-Area Method.
b.Prismoidal Formula
c. Determine the difference in volume between the two methods.
