ABSTRACT: The distribution
system of water on the field of Suka Maju villages is done through tertiary
canal (a soil canal). This can resulted in
waterloss through evapotranspiration, percolation
and seepage so
that conveyance efficiency
of water become so little. Therefor it’s needed to study about
the system further more. This research
was aimedto study the tertiary
irrigation canal in the Suka Maju village Sei Krio Sunggal, Deli Serdang
district. The resultshowed that in the field conveyance efficiency
(at the same
distance) was 68,39%
for canal 1
and 95,92% for
canal 2. Additionally
the sedimentation was also found in the canal, so that it was important
to redesign the dimensions of the tertiary canal. Thus the sedimentation
as well as the scoured
could be reduce.
The best tertiary
canal dimensions for
canal 1 was a combination
of 0,02% slope,
canal width (B)
of 0,42 m and
the depth of
water (D) of
0,21 m, while
for canal 2 a combination
of 0,02% slope, canal width (B) of 0,51 m and the depth of water (D) of 0,26 m.
