Ứng dụng mô hình MIKE 21 FM (HD+ST) đánh giá khả năng tái tạo cát, sỏi, phục vụ quản lý hiệu quả hoạt động khai thác, bảo vệ dòng sông. (Thử nghiệm tại đoạn sông Hồng qua Huyện Phúc Thọ, Hà Nội)

Bài viết trình bày kết quả tính toán mô hình áp dụng thử nghiệm cho đoạn sông qua địa phận huyện Phúc Thọ, thành phố Hà Nội cho thấy, quá trình thành tạo mỏ cát Vĩnh Khang được mô phỏng trong thời gian từ 2010 đến 2019 có sự tái tạo cát mở rộng bãi bồi và vẫn có xu thế tái tạo với tốc độ và quy mô nhỏ hơn trong những năm tiếp theo. | 86 Journal of Mining and Earth Sciences Vol. 61 Issue 4 2020 86-94 Applying MIKE 21 FM HD ST model to evaluate the ability to regenerate sand and gravel for efficient management of river exploitation and protection A case study at Red River crossing Phuc Tho District Hanoi Anh Thuc Thi Nguyen 1 Huan Ngoc Tran 1 2 Huong Thi Vu 3 1 Hanoi University of Natural Resources and Environment Vietnam 2 University of Rostock German 3 Enviromental Water Resources Institude Vietnam ARTICLE INFO ABSTRACT Article history Sand and gravel in River bed are common construction materials Received 02nd Jun. 2020 indispensable in urban development infrastructure and wharves . due to Accepted 23rd July. 2020 the shortage of supply throughout the rivers in Vietnam. Determination Available online 31st Aug. 2020 of the volume of regenerated sand annually or according to a certain cycle Keywords can use the MIKE 21 FM HF ST hydraulic model given by Danish Eploration Institute of Water and Environmental Engineering. Calculation results of the experimental model for the river section across the Phuc Tho district Eploitation Hanoi city show that the Vinh Khang sand mine was more simulated Model MIKE21 FM HD ST during period from 2010 to 2019 and still lower regenaration in the Regeneration Sand comming years. These results will be significal basis for Mining lisener to River bed. orient mine development adjust capacity and limit exploitation in sediment-deficient areas avoid locations where there are high erosion trend. The simulation results from the model also are scientific basis for the state management to make master plane locate sand and gravel material potential areas. But in completing a model it takes time synthesized data of fields such as geology hydrometeorology surveying geophysics it is essential that the functional ministries would make coordinate to bring benefits for organizations and individuals to use lifting data to get high reliability for model results.
