The Estimating of Erosion and Deposition in Basins of East and North of Hormoz Striate (Between of Shoor River and Jask)

Earth landscape generally covered by soil and every deposit. Soil is a dynamic natural material composed of fine particles in which plants grow, and which contain both mineral fragments and organic matter. Soil erosion is the important problems in this time, Human intervention has a major impact in soil . Farmers in most area learned to plant slopes at the same elevation not vertically up and down the slope. Planting on the contour prevents water from flowing straight down the slope and thus reduces soil erosion. The aim in this article is researches for surveying of erosion in east and north basins of Hormoz striate. The rivers in this area are Mazabi, Gaz, Haivi, Shoor, Minab, Jalabi , Jamash and Hasan Langi , tools of this research are every maps for example topographic and geology maps , soil and fertility maps , vegetation and other maps . Farther statistics advantages of hydrometers and meteorology stations and aireal photos and remote sensing and other techniques. The M.Pesiac model is an important tool for analyze of erosion in this basins . For this work, the nine parameters in farther steps examined. Advantages show the quantitative of erosion is 25435/95 tone in per square kilometer and deposit is 5458/48 tone in square kilometer in these basins , The maximum of erosion is in Jask - Sirik basins .
