The watersheds of the Quindío River in Colombia South America have high levels of contamination by total suspended solids (TSS). The objective of this work was to represent the entire hydrographic network of the watersheds of the Quindío department by means of a graph and, using network theory, analyze the different centrality measures to identify areas most prone to TSS contamination. Similarly, partial differential equations were used to simulate the transport of TSS pollutants between specific points of the basin. For this purpose, a network of 409 nodes and 408 edges was created based on topographic maps and reports from the corporations in charge of preserving these watersheds. With information on contamination zones, the network, and partial differential equations, TSS transport was calculated throughout the hydrological network, identifying eight critical zones with high levels of this parameter. Some of these zones are on major rivers, such as the Quindío River near the city of Armenia; the Roble, Espejo, and San Juan rivers also have considerable levels.

使用网络理论模拟山地盆地中总悬浮固体的动力学

哥伦比亚南美洲的金迪奥河流域的总悬浮固体 (TSS) 污染程度很高。这项工作的目的是通过图形表示昆迪奥省流域的整个水文网络，并使用网络理论分析不同的中心性度量，以确定最容易受到 TSS 污染的区域。同样，偏微分方程用于模拟流域特定点之间 TSS 污染物的传输。为此，根据地形图和负责保护这些流域的公司的报告，创建了一个由 409 个节点和 408 个边组成的网络。利用有关污染区、网络和偏微分方程的信息，计算了整个水文网络中的 TSS 传输，确定具有高水平此参数的八个关键区域。其中一些区域位于主要河流上，例如亚美尼亚市附近的金迪奥河；罗布尔河、埃斯佩霍河和圣胡安河也有相当大的水位。
