Fluid Mechanics in soil 2

Navier Stokes equation can be used to simulate fluid flow in soils

• 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:

• 
• 
•
