Abstract

GULLY EROSION is a type of water erosion that tends to land degradation and instability of natural and agricultural lands. Whereas, gully MORPHOLOGY is a function of gully initiation process, so morphological investigations of gully is very important. This research tries to introduce the most important morphological characteristics of gullies in order to MORPHO-CLIMATIC classification of gullied regions in CHAHARMAHAL AND BAKHTIARY province. To this case, two gullied regions covering an area about 500 ha were selected for each climate zone and three representative gullies were chosen in each region. The morphological characteristics were measured in each studied area. Gullied regions were classified using CLUSTER ANALYSIS based on similarity of quantitative characteristics. The most important variables were determined by variance analysis and comparison on mean value of groups. The results indicate that gullied regions in CHAHARMAHAL AND BAKHTIARY province with 245.2 km2 area can be divided to three groups basing on MORPHO-CLIMATIC characteristics. Maximum similarity level in groups was 94.12 percent. A comparison of variance analysis and mean value of variables in groups shows that, annual rainfall , elevation above sea level and gully length were significant in 1% probability level. In addition gullied region area and top width of gully were significant in 5% probability level. The other variables were no significant in separating of groups. Generally, we can emphasize that among all of the morphological characteristics, only gully length and top width of gully have the main role in MORPHO-CLIMATIC classification.
