| 词条 | Reach (geography) |
| 释义 |
A reach is a length of a stream or river, usually suggesting a level, uninterrupted stretch.[1] The beginning and ending points may be selected for geographic, historical or other reasons – and may be based on landmarks such as gauging stations, river miles, natural features, and topography.[2][3] A reach may also be an expanse, or widening, of a stream or river channel. This commonly occurs after the river or stream is dammed. A reach is similar to an arm. The term "reach" can also refer to:
As of 2015, the US Board on Geographic Names records 334 place names in the US with the characterization of a named "reach".[4] See also
