Types of drainage design

Earth Technology

The draining pattern of an area depends on following factors

Geological period of time of draining basin.

Nature, framework and form of rocks.

Slope and topography of these area.

Rainfall, volume of flow and periodicity of movement of drinking water.

TYPES OF DRAINAGE STYLE

Dendritic the term dendritic originiates fromgreek word dendrites (pertaining such as a tree). In dendritic drinking water channels join together in a manner that it is similar to like the twigs of a tree. It is seen in the areas the place that the water programs follow the slope of ground. Example waterways of north plains ganga, Yamuna, and so forth

Trellis drainage with this drainage program the tributaries flow seite an seite to each other and also to the main channel. They sign up for the mainstream of riv at around right sides, thus similar to like trellise. These are you will of collapse mountains. Example- The old collapse mountains of singhbhum( chotanagpur pleateau) has trellis draining pattern.

Rectangular draining: this draining pattern can be marked by simply right angled bends juctions between tributaries and popular. It more irregular as well as its tributaries are neither long nor seite an seite as in trellis pattern. Case ” Square drainage pattern is found in Vindhyas mountains.

Parallel- Here the waterways and its tributaries flow around parallel to each other. It is as a result of steep mountains with some pain relief. Due to steep slopes the streams are often swift and are also almost directly. The estuaries and rivers have hardly any tributaries and all of them circulation in the same direction. Example ” in western ghats, small and swift rivers originiate and adhere to parallel drainage pattern and discharge all their water in Arabian ocean.

Great ” the radial drainage pattern grows when waterways originiating by a hill( central point) flows in all directions and is similar to like the spoke of a steering wheel. Example Kid, Mahanadi, Narmada etc originiating from Amarkantak range and flowing in all directions.

Centripetal drainage- It truly is opposite of Radial draining pattern. In this article rivers discharge there water from all directions within a lake or a depression. Case ” Loktak Lake of Manipur.

Annular draining system ” when the fields flow through approximately round or concentric path along the belt of weak rock system and resemble into a ring like pattern, it is known as annular pattern. Case ” Nilgiri hills seen in Tamilnadu and Kerela features annular drainage pattern.

Deranged draining pattern ” when you cannot find any coherent draining pattern of flow for the rivers and lakes, it truly is referred since deranged drainage pattern. It occurs in regions of geological disruptions like lately vacated glaciers sheets etc . The melting of ice- sheets keep the property with many problems leading to crazed pattern. Case in point ” Deranged drainage routine are found in the glaciated miles of Karakoram range.
