The rate of drainage is directly proportional to the height of the column
of water (this assumes that the medium in question is the same in each

You can demonstrate this in the kitchen sink if you have three sponges of
the same size and shape. They should be dry to start and you add the same
quantity of water to each. Leave one lying flat on it's face, the second is
stood on one side edge and the third is stood up on end. Let them drain for
a time then weigh each one and see which has lost the most water. Or
squeeze them out and measure the volume of water.

If you put an inch of junk in a pot 5" tall, as an example, you will have
reduced it's drainage rate by about 20% and this may not be what you wish
to have happen.
