PPT Downloaded from http://www.pravinkolhe.com/
Land Smoothening: Process of
forming uniform slope in the
direction of irrigation without
changing the natural land
slope.
Land Grading: Process of
developing desired land slope
in the direction of irrigation by
changing natural land slope
Land Leveling: It is the process
of giving zero slope in the
direction of irrigation and as
well as in cross direction.

9. Land Leveling
 This technique is
mainly used for
basin irrigation
where low land
paddy is grown and
field-to-field
irrigation is
practiced.

10.  Infilteration: It is the
downward entry of water
into the soil.
 Infiltration rate (Ir): The
actual rate at which the
water enters the soil under
specified conditions
 Cumulative Infiltration (Y):
It is the quantity of water
that enters the soil in a
given time
 Measurement of
Infilteration:
