context_page_description: 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 the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as part of drainage basins. This is the topographic region from which a stream receives runoff, throughflow, and its saturated equivalent, groundwater flow. The number, size, and shape of the drainage basins varies and the larger and more detailed the topographic map, the more information is available.
context_section_description: In a radial drainage system, the streams radiate outwards from a central high point. Volcanos usually have archetypal radial drainage. Other geological features on which this commonly develops are modest or hard domes and laccoliths. The radical pattern develops when streams flow in many general directions (meaning quite long-term) from a central peak or dome-like structure. 
  In India, the Amarkantak range and Ramgarh crater are most archetypal; and Dogu'a Tembien in Ethiopia.
