Porosity and permeability

Source/Author: David McConnell, Jennifer Wiggen
Subject: What is porosity and permeability
Description: This video briefly introduces the concept of groundwater before explaining how two properties - porosity and permeability - combine to determine the availability of groundwater and the ease with which it travels through rocks and sediment. We show simple bench-top demonstrations to illustrate each property and we calculate what a reasonable porosity value would be for common sediments such as sand and gravel. Finally, we discuss which rocks would best serve as sources of groundwater and which are likely to be barriers to groundwater flow.
