LOCATING WATER TABLE
PLEASE SOMEBODY HELP ME
LINK FOR FIGURE 12.7 https://postimg.org/image/yprycczgb/
LOOK AT THE MAP OF THE INTERLACHEN AREA IN FLORIDA, A KARST LANDSCAPE UNDERLAIN BY HIGHLY SOLUBLE LIMESTONE. IN ADDITION TO SHOWING ANOTHER KARST REGION, THIS MAP ILLUSTRATTES OTHER IMPORTANT CONCEPTS ABOUT GROUNDWATER.
(A) CONSTRUCT A PROFILE OF THE INTERLACHEN AREA FROM POINT A TO POINT B IN FIGURE 12.7. FROM YOUR DATE OF LAKE LEVEL ELEVATION SKETCH THE WATER TABKE ON THIS PROFILE.
(B) DRAW AN ARROW ON FIGURE 12.7 TO INDICATE THE DIRECTION OF GROUNDWATER FLOW.
(C) THE ARE OF INTERLACHEN HAS GROWN DRAMATICALLY IN THE PAST 20 YEARS, AND PART OF ITYS SUBURBAN STREET GRID CAN BE SEEN IN FIGURE 12.7 WHAT COSTRCUCTION PROBLMES DO DEVELOPERS FACE IN AN AREA LIKE THIS .
(D) IN THE PAST YEARS SOME LAES IN THE AREA HAVE SHRUNK DRAMATICALLY OR DRIED UP ENTIRELY? EXPLAIN WHY
Explanation / Answer
A)The profile of the area along AB is constructed,considering a relative height(1cm = 10ft)(not the actual scale).The ground water flow direction is from A to B ie along the direction of decrease in pressure head of water.
B) The flow direction of ground water is from A to B.
C)The area is dominated by Karst topography,hence the ground is weak and unstable,hence the ground would require a lot of strengthing activities prior to construction of civil engineering structures.
D)The Karst landscapes are compose of carbonates,these carbonates can get dissolved in the water and enhance permeability of subsurface rock layers increasing the rate of ground water flow.
It might be a possibility that the ground water might have flown away to lower regions.
