See shape of particle has a role to play in deciding permeability. If we considered void ratio as constant than in that case the soil with angular grain has more specific surface area as compared to rounded grain. Thus the permeability in case of angular grains are less as compared to that of rounded grain. Further with increase in angularity porosity decreases as a result of better packing. So, with increasing angularity the permeability decreases.
Also grain size distribution also help in deciding the permeability. With increase in effective size permeability increases.
So, option D is the correct choice.
Add Answer to:
How does grain angularity and grain size distribution affect a soil's permeability? (Assume the average grain...

Participants in an exercise experiment are asked to rate how difficult a hill-climbing challenge would be when they are rested. A month later, participants are asked to rate how difficult a hill-climbing challenge would be after they have run on a treadmill to exhaustion. The researcher wants to know if people judge hypothetical physical tasks as being more difficult if they are already tired. Assume the rating scale provides interval data that ranges from 0 – very easy to 10...
