This study was conducted aiming to evaluate and compare the land suitability for surface and drip
irrigation systems in Hendijan plain with a surface area of 23500 ha in Khuzestan province, southwest Iran.
In order to perform the land suitability evaluation, the topographic and physiochemical characteristics of soil
were utilized. Parametric approach in terms of FAO framework were used in order to determine the suitability
classes of each soil series for mentioned irrigation systems. The results showed that Capability Index (CI) for
drip irrigation was 65.73 (moderately suitable) while it was 56.38 (marginally suitable) for surface irrigation.
On the other hand, it was found that the soil series 13 with a percentage of 1.40 (330.21 ha), the soil series 1
and 11 with a percentage of 17.35 (4075.19 ha) and the soil series 2, 3 and 12 with a percentage of 29.66
(6967.21 ha) had moderately (S2), marginally (S3) and permanently non suitable (N2) class for both surface
and drip irrigation systems, respectively. As a result, drip irrigation was suggested as the best irrigation system
for more than half of the study area soils due to soil and topographic conditions. Also based on achieved results,
the main limiting factor for both surface and drip irrigation systems in this region was the high quantities of soil
salinity and alkalinity.
Key words: Drip irrigation, FAO framework, land suitability, parametric approach, surface irrigation, ,
