Abstract :
The Availability of water for irrigation purposes can be broadly divided into
two types, namely the availability of water in the land and availability of water in
take buildings. The availability of irrigation water both on land and in buildings is
expected to meet the need of making irrigation water needed in irrigation areas were
reviewed in accordance with its area and cropping patterns that exist.
The research done is to calculate the availability of irrigation water, the water
requirement of rice plants and distribution efficiency. To calculate availability and
water requirements of rice plants needed data as a reference, namely data from the
Meteorology and Geophysics Musi rawas district , while to analyze the efficiency of
distribution used discharge data measured by the method of floating then compared
the results of discharge at the beginning and the discharge end of the channel.
The results of calculations and measurements, availability of water in the
Senaro Village can be fulfilled It can be seen from the average availability, in the first
planting season (September to Januari) average of 0,92 m3/sec with an average water
demand for -0,04 m3/sec and the second planting season (Januari toMei) average of
0,47 m3/sec with an average water demand of 0,04m3/sec. As for the value of the
efficiency of each tertiary channel in Senaro village is 1-4m ka has efficiency values
of 91%, 2-4m ka has efficiency values of 86% ,3-4m ka has efficiency values of 74%
4-4m ka has efficiency value of 64%. 5-4m ka has efficiency value of 72%
