The space–time dynamics and the effect of urban growth on territory transformation were simulated with Iber 2D to analyze flooding events in the lower basin of the Sabinal River, Mexico. We classified the main coverages and land uses of the study area. Soil roughness and water infiltration in the soil were evaluated. Both values were used as input data in a simulation model with Iber 2D to analyze and compare the levels of water height and maximum flood level area with different precipitation values in two reference years, 1986 and 2014. Residential use land cover increased considerably while tree, pasture and agricultural use covers decreased. Consequently, in 2014, precipitation of similar magnitude led to higher values of direct runoff, increasing water levels and therefore the risk of overflowing. The water levels and moments of river overflow provided feedback for flood‐risk warning systems and tools to monitor basins lacking adequate infrastructure.

城市流域溢流阈值的模拟：墨西哥TuxtlaGutiérrez的案例研究

使用Iber 2D模拟了时空动态和城市增长对领土转变的影响，以分析墨西哥萨比纳河下游盆地的洪水事件。我们对研究区域的主要覆盖范围和土地用途进行了分类。评价土壤粗糙度和土壤中的水分入渗。在使用Iber的仿真模型中，两个值都用作输入数据使用二维进行分析和比较两个参考年（1986年和2014年）中不同降水量的水高和最大洪水位面积的水平。住宅用地的覆盖率显着增加，而树木，牧场和农业用地的覆盖率减少。因此，在2014年，类似规模的降水导致直接径流的值更高，水位增加，因此有溢水的风险。水位和河流溢流时刻为洪水风险预警系统和监测缺乏适当基础设施的流域的工具提供了反馈。
