我们回顾了四种排水网络的定量模型。渠道网络的主要特征是自相似性。但网络并不是确定性的，需要考虑到自然的可变性。第一个模型很简单，它考虑了变异性，可以进行检验。然而，由于模型构建中没有明确考虑自相似性，它不能充分地再现观测结果。第二个模型确实考虑了结构中的自相似性，但它没有考虑可变性，因此无法进行测试。第三种模型既考虑了自相似性，又考虑了变异性。第四个模型定义了更坚实的理论基础，但也需要对照观察进行检验。最后，我们强调需要根据观测结果对模型进行彻底的测试，并分析水力几何和水文相似性的含义。©2018年。阿卡德。科伦布。西恩克。前男友。菲斯。纳特。
We review four quantitative models of drainage networks. The main characteristic of channel networks is selfsimilarity. But networks are not deterministic, there is natural variability that needs to be taken into account. The first model is simple, it takes into account variability and can be tested. Nevertheless, it does not reproduce observations adequately because self-similarity is not explicitly considered in the model construction. The second model does consider self-similarity in the construction but it does not take into account variability and it cannot be tested. The third model considers both self-similarity and variability. The fourth model defines a firmer theoretical basis butit also needs testing against observations. We conclude stressing the need for a thorough test of the model against observations and analysing implications for hydraulic geometry and hydrologyc similarity. © 2018. Acad. Colomb. Cienc. Ex. Fis.
