TL;DR
A splash block is the rectangular concrete or plastic trough placed under a downspout outlet to receive roof water and carry it a couple of feet away from the foundation while preventing soil erosion at the discharge point. It works only when sloped away on grade that already falls from the house; on flat or settled ground, water still pools at the wall and a buried extension or drain line does the job instead.
