Question
A hydrographic survey was conducted on a reservoir to determine its capacity by contour
method. The depth of water at sounding point P1 was 10.50m and its elevation at the
bottom was computed to be 210.30m. A sounding point P2 at a distance of 35.45m from
P1 was observed to have a depth of 3.25m and its elevation at the bottom was determined
to be 217.55m.
8. If a subaqueous contour is to be drawn between P1 and P2 with a contour interval
0.50m, how many contours that can be drawn?
a) 10
b) 15
c) 9
d) 17
9. Assuming uniformity of slope from P1 to P2, determine the slope of P1 to P2.
a) 10.45%
b) 15.10%
c) 20.45%
d) 18.46%
