Drainage line Treatment
PURPOSE
|
TREATMENT MEASURE
|
EFFECT
|
Stop further deepening of gullies and retain sediment run-off.
|
Plug the gullies at formation.
|
Stops erosion, recharges Groundwater at the upper level.
|
Reduce run-off velocity, pass cleaner water to the downstream side.
|
Crete temporary barriers in nalas.
|
Delayed flow and increased groundwater recharge.
|
Minimum sedimentation in the storage basins.
|
Use various methods to treat the catchments
|
|
Low construction cost.
|
Use local materials and skills for constructing the structures.
|
Structures at locally maintained.
|
Area Treatment
PURPOSE
|
TREATMENT MEASURE
|
EFFECT
|
Reduce the impact of rain drops on the soil.
|
Develop vegetative cover on the non arable land.
|
Minimum disturbance and displacement of soil particles.
|
Infiltration of water where it falls.
|
Apply water infiltration measures on the area.
|
In-situ soil and moisture conservation.
|
Minimum surface run-off.
|
Store surplus rain water by constructing bunds, ponds in the area.
|
Increased soil moisture in the area, facilitate ground water recharge.
|
Ridge to valley sequencing.
|
Treat the upper catchments first and then process towards the outlet.
|
Economically viable, less risk of damage and longer life of structures of the lower catchments.
