ABSTRACT

One-dimensional models of solute transport typically rely on the Advection-Dispersion Equation (ADE) and thus cannot accurately simulate the solute transport phenomenon in rivers with storage zones. Our proposed model employs a minimum number of parameters (only one parameter) and focuses on simplicity and physical reasoning. This study mainly aims at investigating the applicability of non-linear flux dispersion in the ADE. It then assesses the efficiency of the proposed model using hypothetical and real examples and employing other well-known models. The results of the present study and the observed concentrations indicate that the output of the developed model is highly compatible with the observed ones. Consequently, the proposed model can be recommended as a proper simulation tool of solute transport in rivers with storage zones and replace the available classic simulation models for natural rivers.

摘要

溶质运移的一维模型通常依赖于对流-弥散方程 (ADE)，因此无法准确模拟具有蓄水区的河流中的溶质运移现象。我们提出的模型采用最少数量的参数（只有一个参数），并侧重于简单性和物理推理。本研究主要旨在研究非线性通量色散在 ADE 中的适用性。然后，它使用假设和实际示例并使用其他知名模型来评估所提出模型的效率。本研究的结果和观察到的浓度表明，所开发模型的输出与观察到的模型高度兼容。最后，
