Creek (UK and India)
A tidal inlet, typically in a saltmarsh or mangrove swamp. Alternatively, between enclosed and drained, former saltmarshes or swamps. In these cases, the stream is the tidal stream, the course of the sea-water through the creek channel at low and high tide
A stream smaller than a creek, especially one that is fed by a spring or seep. It is usually small and easily forded. Brook and stream are mutually exclusive terms, with a brook being characterized by its shallowness and its bed being composed solely of rocks.
A stream, brook, beck, burn, crick, or creek, is a body of water with a detectable current, confined within a bed and banks. Stream is also an umbrella term used in the scientific community for all flowing natural waters, regardless of size.
