Abstract
The beneficial use of water resources is one of the important ways of compatibility with drought and preventing desertification process. It should also be tried to use rainfall and surface currents as effectively as possible. The study area including three sites (crescent pond, contour furrow, and control) had the same conditions in terms of topography, general slope, aspect, hydrographic network density, soil texture, and soil structure. Then, 15 transects of 100 meters were laid in each site in a random-systematic way on which 30 plots were established. The plot size was calculated to be 16 square meters using the minimal area method. In each plot, vegetation parameters such as canopy cover percentage, density, and production were measured. The collected data were examined in terms of the homogeneity of variances with Leven test, and the normality of the data was tested using the Kolmogorov-Smirnov test. The differences among the study sites were analyzed with one-way ANOVA using SPSS software. The results showed significant differences among the three study sites (p < 0.05). Our results clearly showed that crescent pond and contour furrow were more effective in restoration and increasing of vegetation cover as compared with control. Moreover, crescent pond was more effective in increasing of vegetation cover.
