Uniformitarianism is the principle that the same physical processes we observe today have operated throughout the geologic past. This means that geological processes that occur today also occurred in the past and at the same rate or intensity, so the study of present-day processes help us understand the past. It does not assume that catastrophic events have regularly occurred or that the Earth is quite young, as these ideas go against the idea of uniformity.
