Tính toán xác định bồi lắng bùn cát hồ Dầu Tiếng bằng phương pháp kết hợp mô hình SWAT, MIKE 11 và 21

Abstract

Dau Tieng reservoir is one of four top-priority ones managed directly by Ministry of Agriculture and Rural Development (MARD). It was constructed in 1981, and has a capacity of 1,58 billion m³ and 470 million m³ of dead storage. It bears duties of supplying irrigation and domestic water for 5 provinces and cities of  Tay Ninh, Binh Duong, Binh Phuoc, Long An and Ho Chi Minh City. Annually, sand extraction of 674.200 m³, has been more or less affecting its operation and safety. Therefore, the research on the sedimentation process of Dau Tieng reservoir brings to us significances of both science and practice. This paper is a brief on results of calculating sediment flow to Dau Tieng reservoir based on the combined method of SWAT, MIKE11 and MIKE21.
