Abstract

The purpose of this Investigation is to recognition areas susceptible to erosion and to study the amount of soil erosion and sediment. The study area is the SimineRood watershed of the city of Bukan with a total area of 1658,872 km2. The erosion zonation map was performed using RS and GIS techniques in 2017, with land use and slope maps, lithology, distance from the road, distance from the waterway, rain fall, soil, and using the Critic weighing method And the WLC method. The results show that the largest area of this basin is located in the high risk area. In the high part of the basin, which is more consistent with the steep slope and rainfall intensity, the most susceptibility to erosion is in the lower parts of the basin, The activity of these factors has decreased, the presence of sensitive formations and poor vegetation also play a determining role in the degree of erosion sensitivity. Keywords: Bukan, Siminerood,sediment, WLC, RS.

Persian Abstract: ﻫﺪف از اﯾﻦ ﺗﺤﻘﯿﻖ ﺷﻨﺎﺧﺖ ﻣﻨﺎﻃﻖ ﻣﺴﺘﻌﺪ ﻓﺮﺳﺎﯾﺶ و ﺑﺮرﺳـﯽ ﻣﯿـﺰان ﻓﺮﺳـﺎﯾﺶ ﺧﺎك و رﺳﻮب می¬باشد. ﻣﻨﻄﻘﻪ ﻣﻮرد ﻣﻄﺎﻟﻌﻪ، حوضه آبريز سیمینه رود شهرستان بوکان با مساحت 4782/1658 كيلومتر مربع می¬باشد، نقشه پهنه¬بندی فرسایش آن با استفاده از تكنيك¬هاي RS و GIS در سال 2017 انجام شد که با نقشه¬های کاربری اراضی و شیب، لیتولوژی، فاصله از جادّه، فاصله از آبراهه، بارش، خاک و با روش وزن¬دهی کرتیک و روش WLC انجام شد. نتایج نشان می¬دهد بیشترین مساحت این حوضه در طبقه پرخطر قرار دارد، در قسمت¬های مرتفع حوضه، که منطبق با شیب¬های تند و شدت بارندگی بیشتر است، بیشترین حساسیت به فرسایش و در قسمت¬های پست‌تر حوضه، از میزان فعالیت این عوامل کاسته شده، وجود سازندهای حساس و پوشش گیاهی ضعیف نیز در میزان حساسیت به فرسایش نقش تعیین‌کننده دارند. واژه¬های کلیدی: بوکان، سیمینه رود، GIS، WLC، RS.
