A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
water area
A body which is made up predominantly of water, e.g. rivers, lakes, oceans, etc.
Relationships      
Parents geographic area A geographic location, generally having definite boundaries. Note that this differs from its immediate superclass Region in that a GeographicArea is a three-dimensional Region of the earth. Accordingly, all astronomical objects other than earth and all one-dimensional and two-dimensional Regions are not classed under GeographicArea.
Children anchorageAnchorage is the subclass of WaterAreas where WaterVehicle may anchor with some shelter or safety. Anchorages may be inside a Harbor or offshore.
 body of waterA BodyOfWater is a connected body of water with established boundaries marked by either geographical features or conventional borders.
 fresh water areaA WaterArea whose Water is not saline, e.g. most rivers and lakes.
 harborHarbor is the subclass of WaterAreas that provide shelter and anchorage for WaterVehicle.
 hydropower water areaHydropowerWaterArea is the class of WaterAreas with waterflow strength adequate for the production of hydropower.
 inland water systemAn instance of InlandWaterSystem comprises two or more lakes or rivers, canals, or other waterways that are interconnected.
 river mouthRiverMouth is the subclass of WaterAreas that are the outfalls of a river or stream into another body of water.
 river systemA RiverSystem comprises all the tributary streams and rivers (StreamWaterAreas) that drain along converging paths into the main river of the system, which discharges into a StaticWaterArea.
 salt water areaA WaterArea whose Water is saline, e.g. oceans and seas.
 ship berthShipBerth is the class of areas where a Ship may be moored, whether at an Anchorage or dock.
 static water areaA WaterArea in which water does not flow constantly or in the same direction, e.g. most lakes and ponds.
 stream water areaA relatively narrow WaterArea where the water flows constantly and in the same direction, e.g. a river, a stream, etc.
 stream water confluenceA StreamWaterConfluence is the place where a stream or other tributary joins a river.
 water currentWaterCurrent is a subclass of FlowRegions consisting of moving water, especially those currents found within a well-identified area and having an established pattern of movement, such as an OceanCurrent, a RipTide, or a River. WaterCurrent is disjoint with StaticWaterArea. As a consequence, Lakes for example cannot be FlowRegions, however, currents may be present in a lake.
 waterwayWaterway is the class of navigable waters, including Oceans, SeaLanes, Rivers, Canals, Lakes, and inland bodies of water.
