groundwater (LEC 10)

Question 1

what are the four distributions of groundwater

Answer 1

zone of soil moisture
capillary fringe
zone of aeration (vadose)
zone of saturation (phreatic)

Question 2

topic: distributions of groundwater

what is the zone of moisture

Answer 2

soil water for plants

Question 3

topic: distributions of groundwater

what is capillary fringe

Answer 3

water held by surface tension (capillary)

Question 4

topic: distributions of groundwater

what is the zone of aeration (vadose)

Answer 4

pores are filled with air and water, water can not be pumped from this zone

Question 5

topic: distributions of groundwater

what is the zone of saturation (phreatic)

Answer 5

all the open spaces of sediments and rocks are completely filled with water, this water is the groundwater

Question 6

for groundwater to move, the pore spaces should be ____________ and _______________

options:
1. small/large
2. connected/unconnected

Answer 6

large enough and connected

Question 7

aquitard (confining layer)
______________ layer that ___________ water movement
(such as clay)

aquifer
_____________ rock layer or sediment that
____________________ groundwater
(such as sands and gravels)

options: impermeable/permeable
prevents/ freely transmits

Answer 7

aquitard:
impermeable; prevents

aquifer:
permeable; freely transmits

Question 8

what is the correlation of bulk density, particle density, and porosity?

for some reason the prof wants us to know the formula?????

Answer 8

n = 1 - (BD/PD)
