Quantitative Analysis of Hydro-Geomorphology Problems of the Likvan Chay Basin with Emphasis to Soil Erosion and Sedimentation (South - East of Ardebil)
The Likvan Chaybasin with 352.72 mm annually precipitation and 5.36% gradient is located on the south-east of Ardebil province. Based on the active tectonic (Bs=2.23), Vf=1.4 & 0.33) vast extension of potentially sensitive formation, impact, runoffs leads to intensive soil erosion. The result of...

| description | The Likvan Chaybasin with 352.72 mm annually precipitation and 5.36% gradient is located on the south-east of Ardebil province. Based on the active tectonic (Bs=2.23), Vf=1.4 & 0.33) vast extension of potentially sensitive formation, impact, runoffs leads to intensive soil erosion. The result of drainage system morphometric, coefficient and geometrical shapes of basin and evaluation of sedimentation with different formulas such as Arnolds, Fournieh, Sepaskhah,… indicate the rate of soil erosion very numerous in the basin. The average erosive caused by rain by results of mentioned formulas is 291.51 ton/ ha/y and the total annually erosion of the soil in the basin is estimated 22446270 ton/ ha/y which indicates high rate of soil erosion. Also the result of some climatic indies such as hydrothermal coefficient and soil wetness' fluctuation showed the basin very prone to gullification and runoffs erosion. The average of PH is 6.14 which desired to cultivation. |
