| Abstract | Experiments were conducted at the Soil and Water Laboratory, A.I.T., Bangkok, Thailand, using the 'Sand Box Model' and a mariotte tube. Three sets of experiment, namely: Experiment I (Triangular furrow, 45° side slope), Experiment II (Rectangular furrow, 13 cm x 18 cm) and Experiment III (Triangular furrow, 30° side slope), were conducted in five trials. The soil used was a mixture of 85% river sand and 15% AIT soil. The soi1 was compacted to 1.5 g-cm-3 and the wetted perimeter in the furrow was maintained at 22 cm. Results showed that furrow shape did not affect the horizontal advance, x, but it did affect the maximum horizontal advance, x • It has been shown also that the vertical advance, y, was greatly affected and a considerable effect was observed in the cumulative infiltration, I. Thus, it has been concluded that in rectangular furrows has deeper depth of penetration. However, it seems that the wider the furrow opening, the deeper the depth of infiltration will be resulting in a higher cumulative infiltration. |
