KAJIAN KOEFISIEN REMBESAN SALURAN IRIGASI PENAMPANG TRAPESIUM PADA TANAH LATOSOL DALAM SKALA LABORATORIUM
ABSTRACT: Seepage is one of
the causes of lost of water in irrigation channel. It is difficult to measure
the seepage directly on the field. Therefore there should be a model or
equation to determine the channel seepage that is the first stage through
laboratory scale. This research was done to analyze the seepage coefficient of
trapezoidal cross-section irrigation channel on Latosol soil through laboratory
scale. The water balance component which was measured were evaporation,
percolation and seepage through channel wall. The research showed that the
coefficient of seepage was about 3732,48 to 5339,52 mm/day. The evaporation
value was 1,33 mm/day and channel percolation was 376,41mm/day.
Key Word: coefficient of
seepage, irrigation channel, trapezoidal cross-section, Latosol soil,
laboratory scale
