A river mouth or stream mouth is a part of a stream where it flows into another stream, river, lake, reservoir, sea, or ocean. At the mouth of a river a delta can form causing sediment pileup. A river can flow into a lake, sea or into an ocean. 1  Confluence. 2  River delta. 3  Estuary. 4  Liman.
A river that meets the sea or a large lake may form a delta at its mouth: a triangle-shaped area of sediment with distributaries flowing across it. The area of water around a river mouth where seawater mixes with freshwater is called an estuary. The land around a stream is a valley.Valleys come in all sizes and have a variety of names, just like streams. The smallest streams, rills, run in tiny channels also called rills.he bottom end is its mouth. In between, the stream flows through its main course or trunk. Streams gain their water through runoff, the combined input of water from the surface and subsurface. Most streams are tributaries, meaning that they drain into other streams.
