TAILIEUCHUNG - Evaluation of soil erosion risk in Da Nang City using remote sensing and GIS technology

Soil erosion is a naturally occurring process in mountainous areas that affects all landforms. Located in Central of Vietnam, in the tropical monsoon climate Da Nang City is characterized by more than 70 percentage of area with hilly and mountainous topography. This study is objective apply the Universal Soil Loss Equation (ULSE) model developed by Wischmeier and Smith (1978) integrating with remote sensing data and Geographical Information System (GIS) tool to evaluate soil erosion risk in Da Nang City, Vietnam. | Rerearch paper Evaluation of soil erosion risk in Da Nang City using remote sensing and GIS technology Tran Thi An1 Truong Phuoc Minh2 Le Ngoc Hanh2 Nguyen Thi Dieu2 Hoang Thi Dieu Huong2 Tran Thi Tuyen3 1 Faculty of Management Science Thu Dau Mot University Binh Duong Vietnam antt@ 2 Faculty of Geography University of Science and Education The University of Da Nang Vietnam. tpminh@ lnhanh@ ntdieu@ htdhuong@. 3 Faculty of Management of Natural Resources and Environment School of Agriculture and Natural Resources Vinh University tuyentt@ Corresponding author tuyentt@ Tel. 84 Received 5 February 2022 Accepted 11 March 2022 Published 25 April 2022 Abstract Soil erosion is a naturally occurring process in mountainous areas that affects all landforms. Located in Central of Vietnam in the tropical monsoon climate Da Nang City is characterized by more than 70 percentage of area with hilly and mountainous topography. This study is objective apply the Universal Soil Loss Equation ULSE model developed by Wischmeier and Smith 1978 integrating with remote sensing data and Geographical Information System GIS tool to evaluate soil erosion risk in Da Nang City Vietnam. Rainfall erosivity R slope length steepness LS soil erodibility K cover management C and conversation practice P were used to generate soil erosion map of Da Nang City. In this research Open Source Geographical Resources Analysis Support System GRASS GIS and QGIS tools were used for developing potential soil erosion map for study area. This study has revealed that the erosion in the Da Nang City has been changed compared to the potential erosion map. The high erosion levels above 50 tons ha year and the low erosion level less than 5 tons ha year have decreased erosion at medium levels increased significantly. Thus after adding the vegetation cover the amount of soil loss changes to the direction of .
