Reach hydrology
WebThis short review extensively synthesizes information available in the long-term hydrologic changes experienced by the Apalachicola River in Florida, throughout its reach. Hydrologic changes in this river were induced by human interference along the river reach. A reach is a segment of a stream, river, or arm of the sea, usually suggesting a straight, level, uninterrupted stretch. They are traditionally defined by the capabilities of sailing boats, as a stretch of a watercourse which, because it is straightish, can be sailed in one reach (that is, without tacking). Reaches are often named by those using the river, and a reach may be named for landmarks, nat…
