If water can pass through a surface, the surface is permeable.
predict the permeability of gravel
Gravel Very high permeability
predict the permeability of sand
Sand High permeability
If water cannot pass through a surface, the surface is impermeable.
Predict the permeability of silt
Silt Low permeability
Predict the permeability of clay
Clay Very low permeability
Run-off: Water that does not soak into the ground or evaporate, but instead flows across the land
Let’s see how permeability affects our daily life.
Do you think the surfaces in urban areas permeable or impermeable?
Conclusions 1. Different land cover affects water runoff during/after storms in different ways. 2. Human habitation changes land cover 3. Communities need to be careful about how land is used.
When it Rains it Pours Todays Goal: To understand how water is absorbed into the ground. To be able to explain the difference between pervious and impervious.
GROUND WATER. POINTS TO BE COVERED ON GROUND WATER 1.How does ground water move? What is porosity? permeability? Infiltration? 2.How is ground water formed?
