the term natural drainage means the natural run off of water from an area in rivers and streams . Drainage pattern, drainage system and network of rivers are terms use dto describe the nautural drainage of an area. ( extracted from 'THE ENVIRONMENT OF Pakistan " By Huma Naz Sethi )
Four main types of stream drainage patterns are Dendritic, Radial, Rectangular, and Trellis.
Dendritic looks like tree branches, with the river being the trunk and the tributary streams being the branches.
Radial starts from a center point, usually on a mountain top, and works downward in all directions.
Rectangular forms distinct changes in direction (rectangles) because the streams follow less-strong rocks.
Trellis forms long lines (the rivers) with tiny streams jutting out at all sides.
The dendritic pattern is the most common drainage pattern
The four types of Drainage patterns are:-
What is radial drainage
A drainage map shows the watershed of an area, the direction and elevation that water flows from into a stream, river, or lake.
trellis
surface drainage system
Surface drainage systems.
Rocky slopes mean little vegetation. Drainage also affects vegetation, if there is poor drainage in an area, there are most likely going to be swamps that arise.
Dentritic drainage patterns are like tree branches and represent the most common drainage pattern
dendritic drainage pattern.
Ordinarily, a dendritic drainage pattern. That is, resembling the branches of a tree. Another common pattern is a fault controlled drainage pattern, where major geologic features control the drainage pattern. There are several other systems.
Dendrtitic river system has a tree like pattern (more common) and trellis river system has a rectangular pattern throughout

Dendritic drainage pattern.
Inner drainage, interior drainage, internal draqinage, inland drainage, closed drainage, endor(h)eism -- a pattern of streams that drain toward the centre of a basin rather than toward the sea.Ref: Dictionary Geotechnical Engineering by Herbert Bucksch (Page 327).
