It is believed that forests are effective in producing water, preventing floods and reducing soil erosion. Today, using advanced techniques and the latest technologies, floods are directed to aquifers, to make optimal use of the minimum rainfall, especially in arid and semi-arid regions. It is possible to create vegetation and especially to create a forest park in the urban suburb of arid and semi-arid areas. Therefore, this study seeks to evaluate the role of flood spreading in the creation of tree vegetation. Therefore, in this study, soil moisture storage and the amount and speed of permeability in the treatment without flood spreading and flood spreading in arboreal vegetation (dense forest) were investigated. The results show that the cost-effectiveness index in flood spreading treatment with tree cover is less than flood spreading treatment without tree cover (rangeland). In fact, combining flood spreading with planting trees is less than planting shrubs at 88000 Rials per cubic meter of water. Therefore, by using flood spreading technology and combining with suitable tree species, in addition to increasing the effectiveness of moisture retention, more water can be stored to penetrate the aquifer into the soil.
