True
False
The leading cause of climate change is
CO2 emission to the atmospher
Increase of the temperature of the sun
Change of the location of eart
Which equations should be used for modeling water flow in soils:
Darcy's law and continuity equation
Darcy's law
Darcy's law an Navier Stokes
This figure represents:
Groundwater recharge
Landslide
seawater intrusion
This figure represents:
Seawater intrusion in coastal aquifer
CO2 storage in saline aquifer
groundwater recharge
Seawater intrusion occurs due
aquifer overpumping
groundwater recharge
CO2 injection in aquifers
In this figure (h) represents:
The pressure head
The pressure
The hydraulic head
The hydraulic head is defined as
H=h+z
H=h-z
H=h x z
Fluid flow in porous media occurs due to the gradient of the hydraulic head
True
False
The Darcy's law is given by:
In darcy"s law (K) is
The ydraulic conductivity
The porosity
The temperature
The unit of the hydraulic conductivity is:
m2
m/s
unit less
For sand the hydraulic conduction is between
10-5 - 10-2
10 - 100
10-15 - 10-10
