تحليل مناطق نشاط التعرية المائية في حوض وادي تويلكة

Abstract EN

Wadi Twilka is located in Sulaymaniyah Governorate, east of Chamchamal district, in northern Iraq, at latitudes (35 ° 04'24.0 ") and (35 ° 18'34.0") in the north, and longitudes (45 ° 09'30.0 ”) and (45 ° 25'20.0 ") to the east, with an area of (264.92 km2), erosion within the basin boundaries was estimated by multiple models, so collision rain erosion was calculated using the (Forneh -Ornalds) law, then groove erosion was found according to the Bergsme law, as well as laminar erosion affected by the slope, and for the purpose of producing maps that take into account most of the rain-erosion areas, the final erosion map was produced (after overly and then collecting process) by adopting maps of the Previous types of erosion.

It was found that the areas of severe and very severe erosion in the basin of the research area formed (26.68% ) and (11.11% ), respectively, with an area exceeding (94) km2, concentrated in the middle of the basin as well as the southern regions of it and part of its northern regions.
