GROUNDWATER

 Expand the GROUNDWATER folder. Double‑click and primeeded Gray County, Kansas.

This is Gray County, Kansas. As you can ascertain from the core pivot irrigation circles, tillage is the dominant plant use in the county. The Arkansas Large stream – popular west to east – bisects the county. There is not abundance instil in the large stream to cater adapted instil for irrigation. Therefore, instil fountain for irrigation is premisewater.

We cannot see the aquifer that is supplying the instil for irrigation, but we do entertain polite notice that indicates the profundity of the instil board. In unconcealed, we feign the deeper the instil board, the deeper the polite.

 Double‑click and primeeded Well Depths.

This map shows the profundity of the instil board. It was formd using grounds from 100 polites. The further yellow the area, the shalinferior the polite and the further blue-colored, the deeper. The deepest polites entertain a profundity of closely 500 feet.

 Double‑click and primeed, Surface Profile. Right‑click Surface Profile, and then primeeded Show Superiority Profile.

This surface propolish verse is closely 25 miles in elongation and the superiority varies by 24 meters merely. This is not abundantly qualify in superiority aggravate 25 miles.

With the superiority propolish showing at the floor of the fence, run your cursor parallel the x-axis. Look at the collocation of the red arrow, referring-to to the polite profundity map.

Question 25: What is the homogeneity betwixt demeanor superiority and polite profundity?

A.   In unconcealed, the nobleer the plant superiority, the deeper the polite profundity

B.   In unconcealed, the inferior the plant superiority, the deeper the polite profundity

C.   In unconcealed, the nobleer the plant superiority, the shalinferior the polite profundity

D.   Unable to ascertain from vision

 

Question 26: What does this homogeneity intimate?

A.   In this area, premiseinstil flattens tends to mollify and lapse delay the topography of the plant

B.   In this area, premiseinstil flattens are referring-toly the same

C.   In this area, polites are merely bored where the premiseinstil flatten is neighboring the demeanor

D.   Unable to particularize.

 Double‑click and primeeded Withdrawal.

This is a map of the Noble Plains aquifer showing qualifys in the instil board flatten for a twenty year epoch (1980-1999). Green areas are referring-toly firmly-fixed, but as the falsification qualifys from yellow to red to pink, the flatten of the instil board lapses, aggravate 60 feet in the pink areas. The dominant plant use is tillage.

Question 27: Why is the instil flatten in some portions of the Noble Plains aquifer detriment? (Check all that use).

A.   Agricultural use is delaydrawing instil

B.   Recharge rates are short than delaydrawal rates

C.   Recharge rates are further than delaydrawal rates

D.   Unable to particularize
