黄河泥沙科学的新进展

New Developments of Sediment Science of the Yellow River

泥沙问题是黄河难治的症结，本文系统回顾了黄河泥沙科学的新进展，其中包括水流泥沙运动、黄河水流挟沙力、高含沙水流运动、河床演变规律和减淤措施研究、泥沙数学模型、河工动庆模型试验研究等方面，并提出了有待于今后深入研究的主要课题。

The key difficulty in regulation of the Yellow River is to control sediment. The new developments of sediment science, including sediment flow movement, capacity of sediment transportation, hyperconcentrated flow movement, river evolution and regulaion laws, measures of deposition abatement, mathematical model and physical model of engineering sediment, etc., are reviewed in this paper and main problems needed to be studied deeply are also presented.
