Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...
The Digital Chart of the World (DCW) is a comprehensive digital map of Earth. It is the most comprehensive geographical information system (GIS) global database that is freely available as of 2006, although it has not been updated since 1992.
A drainage divide, water divide, ridgeline, [1] watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges , and may be in the form of a single range of hills or mountains , known as a dividing range .
The eastern drainage flows into the watersheds of the Susquehanna River, Potomac River, and James River, all of which flow into Chesapeake Bay before entering the Atlantic Ocean. At its northern terminus, the Eastern Continental Divide originates at Triple Divide Peak [ a ] in Ulysses Township, Pennsylvania , about 10 mi (16 km) south of the ...
In water supply system drawing there will be hot water piping and cold water piping and hot water return piping also. In drainage system drawings there will be waste piping, Soil piping and vent piping. The set of drawing of each system like water supply, drainage etc is consist of Plans, Riser diagram, Installation details, Legends, Notes.
Point drainage, which intercepts water at gullies (points). Gullies connect to drainage pipes beneath the ground surface, so deep excavation is required to facilitate this system. Support for deep trenches is required in the shape of planking, strutting or shoring. Channel drainage, which intercepts water along the entire run of the channel.
Drainage basin of the Ohio River, part of the Mississippi River drainage basin. In hydrology, the drainage basin is a logical unit of focus [clarification needed] for studying the movement of water within the hydrological cycle. The process of finding a drainage boundary is referred to as watershed delineation. Finding the area and extent of a ...
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.
