摘要: 沿程淤积与溯源淤积是有关河床纵剖面调整的一对重要概念,但以前的一些文章对此的认识是互相矛盾的。本文对沿程淤积和溯源淤积的概念作了严格的限定,并给出了数量化的定义——沿程淤积与溯源淤积的数学模型。

关键词: 沿程淤积, 溯源淤积, 数学模型, 侵蚀基准面

Abstract: Downward sedimentation and headward sedimentation are a pair of important concepts concerning the regulation of the river bed profile, Because of the inconsequent understanding of above two concepts existing in earlier papers, this paper gives new and strict definitions of them as well as their mathematical model.
