Watershed Management

Outlet

Ridge line

Drainage line

Watershed is a geo-hydrological unit (Ha)

which drains to a common point on a natural

drainage system.


2/13

To promote the socio-economic development of village community

through optimum utilisation of natural resources

To harvest runoff and to recharge ground water

To conserve water, soil and vegetation effectively To promote sustainable farming

To cover the non-arable areas effectively through afforestation and

pasture land development

To improve the economic and social condition of the resource poor

and disadvantaged sections of the watershed community, by

adopting alternate enterprises

Restoration of ecological balance

Prevents nutrient

and fertile soil loss

Conserves moistureIncreases the

productivity

Contour bunds constructed along contour to check soilerosion or in situ moisture conservation fortified with localvegetation

Nadi

Water Harvesting Structure in the

field for life saving irrigation


6/13

Khadin

Water Harvesting Structure (khadin)It is an earthen bund constructed across the slope on flatter lands in the desertareas where rain water is received from relatively impervious uplands withgentel slopes. The submerged land of the khadinis cultivable both in KharifandRabidepending upon the quantity of runoff received


7/13

Tanka

Tanka is a pucca storage tank in the desert areas that collects runoff waterfrom artificial catchment constructed around it

It is used for harvesting surface runoff water for dryland horticulture/agroforestry and drinking purposes.


8/13

Earthen check damsIt is an earthen embankment, usually constructed in nallah bed across thedrainage lines and are fortified with dry stone pitching or vegetation. These are

preferred in rilles/ gullies to check soil erosion, ground water recharge &drinking water for live stock.


9/13

Loose stone check damsThese structures are constructed in small and medium size gullies/ valley

using locally available stones/ boulders as dry masonry to check erosive

velocity of runoff and to arrest silt carried by runoff.


10/13

Vegetative Gully plugs

These check dams are usually preferred in rills/ gullies having smaller catchment area toarrest soil and water .Mainly grass and shrubs like Agave, Ipomea.

, Ratanjot, Vetiver etc are planted across the drainage line.


11/13

Agro forestrySuitable forestry plants like

Khejri, Ardoo, Desi Babool,

Neem, Kumtha etc. are plantedon the field boundaries to meet

the fuel & fodder requirements of

the farmer.

Horticulture Insurance in Drought

Improves the income

Proper nutrition of the cultivators.


12/13

Silvi-Pasture development works are implemented on community land to meet out fuel

fodder demant of the community at large at the same time such works help in improvin

degraded lands.


13/13

Anicut is a weir structure constructed across the natural drain for

impounding the water in the drain. This helps in recharging of

surrounding wells and store water.
