Tính toán lưu lượng trầm tích của các lưu vực ven biển nhỏ: sự điều chỉnh của các phương trình toàn cầu
Tóm tắt
Hai loại phương trình hồi quy được sử dụng để tái tạo lưu lượng trầm tích của 26 lưu vực ven biển nhỏ ở phía đông nam Trung Quốc. Loại đầu tiên là các phương trình toàn cầu được đề xuất bởi Milliman và Syvitski (1992), Mulder và Syvitski (1996), Syvitski et al. (2003), và Syvitski và Milliman (2007). Loại thứ hai là các phương trình đã được sửa đổi theo các đặc điểm của các lưu vực ven biển, bao gồm diện tích lưu vực, lưu lượng nước trung bình và lưu lượng trầm tích trung bình. So với các quan sát từ các trạm thủy văn, các phương trình toàn cầu đã ước lượng lưu lượng trầm tích cao hơn 1–2 bậc kích cỡ. Bằng cách sử dụng các phương trình được sửa đổi, độ chính xác của ước lượng lưu lượng trầm tích đã được cải thiện đáng kể, với sai số tương đối trong khoảng 7%–24%. Nguyên nhân của sự ước lượng quá cao chủ yếu do sự khác nhau về miền của các tham số và hệ số hồi quy giữa các con sông toàn cầu và các lưu vực ven biển nghiên cứu. Nghiên cứu này chứng minh rằng cần phải tính đến sự điều chỉnh khi sử dụng các phương trình hồi quy toàn cầu để tái tạo lưu lượng trầm tích của các lưu vực ven biển nhỏ ở phía đông nam Trung Quốc.
