Confusion on the last slide in lecture 9
Fragment of a discussion from Course talk:APBI200
1st Dexter, be careful with lower versus higher AEV. The graph indicates matric potential (which is negative), and you indicate tension.
As the graph shows matric potential..... In the sand, AEV corresponds to a higher matric potential i.e. closer to zero; and as you indicate this means that there are larger pores in the sand (i.e. they drain at a high matric potential). Additionally, as the curve drops at high matric potential and is steep, this indicates that most of the pores are large.
Comparing massive clay and the aggregated clay. What is the difference in pore size distribution in the aggregated clay compared to the massive clay (and why)?
