Abstract:
The main objective of this research is to compare two
different irrigation methods according to parametric evaluation system
in an area of 15831 ha in the North Molasani region`s soil located in
Khuzestan province, Southwest Iran. Soil properties of the study area
including texture, depth, electrical conductivity, drainage, carbonate
content and slope were derived from a semi-detailed soil study regarding
North Molasani plain in a scale of 1/20000. After analyzing and evaluating
soil properties, suitability maps were generated for both methods by means
of Remote Sensing (RS) and Geographic Information System (GIS). The results
showed that 163 ha of the studied area were highly suitable for Surface
Irrigation methods. Whereas 2288 ha of the study area was highly suitable
for drip irrigation methods. Also, it was found that some series coded
2, 3 and 5 covering an area of 7582 ha, were not suitable to be used for
surface irrigation systems and two series coded 3 and 5 with an area of
1381 ha were classified not suitable for drip irrigation systems. Moreover,
the results indicate that by applying drip irrigation instead of surface
irrigation methods, suitability classes of 8732 ha (55.16%) of North Molasani
plain`s land will improved. Ultimately, drip irrigation system was suggested
as the best method to be applied to the said study area. The main limiting
factors in using both surface and drip irrigation methods in this area
were soil carbonate and drainage.
