Water & Soil Management
Level 2 Guiding Question:what does porosity and permeability tell us about our soil?
The permeability of a soil is the ability of water to move through it (permeate it). It depends on the physical and chemical properties of the soil, notably particle size distribution (the range of particle sizes present), pore space, pore size and the continuity of the spaces. While porosity is the percentage of pore space that is taken up by water. The space between particles is called pore space. Pore space determines the amount of water that a given volume of soil can hold. Porosity refers to how many pores, or holes, a soil has.The porosity of a soil is expressed as a percentage of the total volume of the soil material.

Level 2 Videos: Porosity and permeability
Level 2 Elaborate: How will you define the difference between Permeability and Porosity?
Once you have completed the lab and the conclusion go the website Vocaroo.com and record your explanation of the difference between of permeability and porosity. Don't forget to define each word and give an explanation of the differences and finally give examples of what each is like. Once you have completed the audio file email it to your instructor (see VDO below ).
