Effects of Land Cover Change on Surface Runoff Using GIS and Remote Sensing: A Case Study Duhok Sub-basin پێشکەش بە ئامادەبووانی بەڕێز کرد. 

پۆختەی سمینار: 

A catchment area is an area from which runoff is resulting from precipitation flows. Land cover changes are the most significant factors that directly impact the runoff process. Dueto urbanization, the continuous growth in urban areas has led to a significant transformation of land cover pattern in built-up areas which has significantly affected the surface runoff behavior in the urban realm. The objective of the study is to examine the impact of projected land cover changes on runoff in the Duhok sub-basin during the study period of 1990–2016. The study describes long-term hydrological responses within the quickly developing watershed of Duhok. Land use and land cover were integrated with a hydrological model SCS-CN to compute the runoff volume from the catchment area. Yearly average storm event rainfall data was used as a hydrological input to the SCS-CN model to estimate surface runoff over the years due to changes in the land cover of the Duhok watershed. The study indicates that the urban growth of thewatershed increased from 10% in 1990 to 70% in 2016. Surface runoff volume increased from 12% in 1990 to 36% in 2016, while the vegetation land decreased from 47 to 14% in the same period. The study points out that an increment in built-up area or barren land cover and a decrease in vegetation cover have occurred, leading to larger surface runoff volumes in urban catchment areas.
