As everyone in our Environmental Science class know: porosity, permeability and retention are related one to another. Here are the meanings for each one;
Porosity: Volume of water that fits between the soil particles.
Permeability: Rate of flow of water through soil.
Retention: How much water is 'trapped' by soil.
Porosity and Permeability are directly related, when one is high the other is high too, and percent water retention is inversely related to both. We can see those things on common or not in the last lab we did. Just seeing the numbers on the data you see their are related, I don't remember really well the data because I turn in it but the gravel porosity was like 4 cm per second and the permeability 55%, that tell us that they are directly related, if one goes up the other goes up too.
We should care about it because depending on the porosity and permeability is how much water it will have, and that is all about LIFE.
