Abstract

FLOODWATER SPREADING is an efficient and appropriate method for the optimization of runoff utilization, particularly in arid and semiarid region. Beside the reduction of damage caused by the floodwater, this technique would also be useful in the artificial recharge of groundwater, rangeland rehabilitation and desertification control. This research was conducted on the effects of FLOODWATER SPREADING on some of the characteristics of VEGETATION and SOIL SURFACE parameters. Two key areas were selected within and outside FLOODWATER SPREADING in the GAREH BYGONE plain. Three transects of 100 m were selected on each key area and 30 random plots of 4 m2 were sampled systematically. Canopy coverage and density of different species were measured using plots and production was measured by double sampling method. To assess the soil characteristics, 6 profiles were dug along each transects, which 3 of them was under story and the other was outside of canopy coverage of shrubs. Statistical results indicated that FLOODWATER SPREADING have significant effect on canopy cover and production. So density of dominant shrub (Helianthemum lippii) was significantly increase in FLOODWATER SPREADING area (p<0.05). FLOODWATER SPREADING significantly reduces the pH but increased the electrical conductivity, Organic matter and total nitrogen in the SOIL SURFACE (p<0.05).
