What is the effect of increasing the drainage path length on the rate of consolidation?

Step 1: Understand what consolidation means. Consolidation is the process where soil decreases in volume due to the expulsion of water from its pores.
Step 2: Know that drainage path length is the distance that pore water must travel to escape from the soil.
Step 3: Realize that if the drainage path length is increased, the water has to travel a longer distance.
Step 4: Understand that the longer the water has to travel, the longer it takes for the water to escape.
Step 5: Conclude that if it takes longer for the water to escape, the rate of consolidation will decrease.
