Description:

Conventional check dams are base don the gravity dam principal, which are heavy dams, difficult to construct (since they use RCC) and costly. The innovative checkdam is based on the arch load bearing principal, which drastically reduces the material and therefore the cost of construction of the check dam. Also, this check dam can be constructed usieng locally available material like stone blocks, bricks etc. and is therefore easier to construct.

The innovator of this design, Sh. Bhanjibhai Mathukiya, is an illiterate small farmer but a creative artisan. He has also developed small three and four wheel tractors for small and marginal farmers.
