A checkdam constructed from stone, wood or branches of trees. It has an average height of 1m and is spaced at 1m vertical interval. The purpose is to reclaim gully lands to productive lands by controllong the rate of runoff and trapping the soil. By plugging the gully using different checkdams the gully gradient is brought to a gentle slope and flow rates and soil movment is regulated. Constructing of checkdam in a gully starts with smaller checkdams which are regularly maintained and up graded of their heights. Gully plugging by checkdams and vegetative material is suitable to all agro-climatic conditions but the choice of material for establishment depends on the availability of material in the nearby and rate of flow. For a high rate and volume of flows stone checkdams are prefered to wooden or earth chekdams.
