PLANNING SUPPORT BUILDINGS IN THE TISSUES IRRIGATION STEMS ANAI PHASE II DISTRICT THE PADANG PARIAMAN

Abstract

Irrigation is an effort to obtain water using buildings and channel for agricultural purposes.
The Irrigation Shaft Mounds (13.604 ha) is an Irrigation Area in West Sumatra that was
implemented in phases where phase I (6,575 Ha) have been completed and the remaining
phase II covering 6.840 Ha. The purpose of this writing is to analyze the needs of water in
the rice fields with the availability of water in the irrigation area of the Shaft Mounds And
the plane complementary building along irrigation canals. Data - data that are needed in
writing is obtained through, observation ( direct observation ), consultation, literature
( review of pustaka ). Debit calculation method using Mock F.J. mainstay, for 10 years,
from the year 2002 to the year 2011. Based on water balance graph can be recommended:
the alternative clean water needs looks I in the rice fields of maximum (Net Requirement
Field/N.F.R) for 0,783 ltr/sec/ha, the primary Building dimensions Results obtained with a
value of 1.50 m (b), (h) 0.80 m, (w) 0.20 m, (m) 1.5 m. Skunder Building (b) 0.70 m, 0.04
