Comparing soil physico-chemical characteristics and trapezoidal and v-shaped gully morphology with different land uses in dry areas, case study: Hossinzahi and Nalint regions of Chabahar

The aim of this research was to compare the soil physico-chemical characteristics and the morphology of two types of gullies in dry areas. In this research, places with gully erosion were recognized. Then, two trapezoidal and V-shaped gullies were selected based on soil physico-chemical characteristics and gully morphology. Gullies’ length and their wide at the head and 25, 50 and 75 percent of the length were measured. The area, mean depth, mean wide, soil depth, head plan, overall plan, slope cross section shape, also, gully erosion reasons were investigated. Soil samples were taken from 25, 50 and 75 percent of the length and from the end of gulliesThe data were analyzed using SPSS software. Results showed that soil parameters such as EC, clay, CEC, SAR, Ca Mg and So4-- at the 0.05 level (P
