không tuyến quan trọng trục đường thủy Việt Trì Tuyên Quang mà cịn tuyến lũ quan trọng hệ thống sơng Lơ Trong tình hình kinh tế nay, nước ta lại nước phát triển nên tuyến giao thơng thủy Hà Nội – Việt Trì – Tun Quang tuyến giao thông quan trọng việc vận chuyển hàng khách, đóng góp niều cho phát triển kinh tế xã hội tỉnh Tuyên Quang, tỉnh Phú Thọ, tỉnh Vĩnh Phúc tỉnh lân cận Vì sơng ngồi việc có nhiệm vụ tiêu lũ lâu dài cho lưu vực cịn phải đảm bảo quan hệ hình thái cho việc giao thông thủy thuận lợi, đem lại hiệu kinh tế cao Tuy sau thời gian dài khai thác tuyến giao thơng thủy Việt Trì – Tuyên Quang nhiều đoạn sông bắt đầu bị thay đổi chế độ thủy động lực diễn biến lòng dẫn Nhiều đoạn sông bị thu hẹp mở rộng, xuất bãi bồi, hố xói, điều dẫn đến thay đổi khả tiêu thoát lũ qua đoạn sơng này, từ ảnh hưởng đến tồn q trình lũ hệ thống sơng Khơng thế, việc thay đổi cịn ảnh hưởng khơng tới việc lại tàu thuyền sông, làm giảm hiệu ngành kinh tế đường sông Về mùa nước kiệt, việc xuất bãi bồi lớn sông làm tê liệt tuyến giao thông đường thủy nội địa quan trọng Việt Trì - Tuyên Quang Do đặc thù đoạn sông Lô qua Đoan Hùng là: có cửa phân lưu sơng Chảy có đoạn thắt hẹp nên chế độ thuỷ động lực diễn biến lịng dẫn đoạn sơng phức tạp tồn hệ thống sơng Lơ Cùng với phát triển kinh tế xây dựng dẫn đến nhu cầu khai thác cát, sỏi sông diễn mạnh mẽ, điều làm cho diễn biến lịng dẫn đoạn sơng lại phức tạp thêm Trước tình hình thực tế trên, muốn chỉnh trị tổng thể đoạn sông phục vụ đa mục tiêu, đáp ứng nhu cầu ngành kinh tế cần thiết phải nghiên cứu chế độ thuỷ động lực quy luật diễn biến lòng dẫn đoạn sơng tình hình Từ đề xuất giải pháp chỉnh trị phù hợp để ổn định lịng dẫn, phục vụ giao thơng thuỷ lũ an tồn Đây lý cho thấy cần thiết đề tài luận văn nghiên cứu: “Nghiên cứu chế độ thủy động lực
