Analysis of the environmental suitability of agricultural land by the impact of groove erosion in the Tawilka Valley basin (Applied Geomorphological Study)

Abstract

Tawilka Valley basin is located in the Governorate of Sulaymaniyah, an area of (264.92 km2), the research aims to study the environmental potentials provided by the basin for agricultural activity as well as the risks of geomorphic erosion that stand in the way of it, the research identified major problems are (what is the area of arable land that is not affected by erosion The gully in the Tuilika Valley basin? What is the environmental status of the basin and what it offers of properties that help in agriculture?) , The research adopted the methodology (the deductive or inductive method) as well as the statistical analysis, and the research found that (114,53 km2), i.e. (43,25%) of the research area is suitable for agriculture within the outputs of the environmental suitability of agricultural lands, and the areas of severe erosion to very severe has an area of (0,80 km2) and high to severe erosion (139,19 km2) and it constitutes (52,53%) of the basin , As for the outputs of congruence between appropriateness and erosion, the area suitable for cultivation has become (161.38 km2), at a rate of (61.13%) of the research area. Valid for grazing and forests, while the most important recommendations were to pay attention to the agricultural reality in the basin and increase the area of agricultural lands to produce the various crops required locally and regionally.
