Abstract
El trabajo de investigación “Modelamiento de la zona de inundación en el margen del Rio Magdalena en el municipio de Girardot-Cundinamarca” tiene como fin determinar las posibles zonas de inundación para la comunidad rivereña, y así evitar que sufran de daños personales y materiales a causa de los desastres naturales, se modelo una huella de inundación, realizando un análisis de los caudales históricos del rio magdalena de las estaciones más cerca a Girardot, tales como, Neiva, Natagaima, Purificación, Nariño y Guaduas, después de obtener estos datos de la plataforma del IDEAM, se procede a hacer una cuantificación por el método Estocástico y con las fórmulas de cálculo de datos faltantes por promedios para series Determinísticas, una vez teniendo las tablas completas, se realizó un histograma para tener más clara la variación de las cinco estaciones ya que por medio de HEC-RAS se modelo la batimetría del rio que fue facilitada por la empresa SAP agregados, y con los caudales históricos se pudieron hallar los caudales para los periodos de retorno para 10, 25, 50 y 100 años, luego se procedió a modelar esa información a HEC-RAS para saber la cota de la lámina de dichos caudales, por medio de la plataforma de Colombia en Mapas, Google Earth Pro y Grilla de 1:25000 de Colombia, se buscó que marco servía para el sitio a desarrollar, que fue en el municipio de Girardot en el rio magdalena, se descargó y se extrajeron las curvas de nivel para desarrollar en ArcGIS el modelo digital de elevación en 2D, ese modelo se pasó a ArcScene se digito a 3D al igual que la imagen descargada de la grilla y se calcularon la zona de inundación con las cotas ya establecidas en HEC-RAS.
The research work "Modeling of the flood zone on the banks of the Magdalena River in the municipality of Girardot-Cundinamarca" aims to determine the possible flood zones for the river community, and thus prevent them from suffering personal and material damage to cause of natural disasters, a flood footprint was modeled, performing an analysis of the historical flows of the Magdalena River from the stations closest to Girardot, such as Neiva, Natagaima, Purificación, Nariño and Guaduas, after obtaining these data from the IDEAM platform, a quantification is made by the Stochastic method and with the formulas for calculating the missing data by averages for Deterministic series, once having the complete tables, a histogram was made to have a clearer view of the variation of the five stations since through HEC-RAS the bathymetry of the river was modeled, which was provided by the company SAP aggregates, and with the historical flows s it was possible to find the flows for the return periods for 10, 25, 50 and 100 years, then proceeded to model that information to HEC-RAS to know the level of the lamina of said flows, through the platform of Colombia in Maps, Google Earth Pro and Grid of 1:25000 of Colombia, it was found which framework was used for the site to be developed, which was in the municipality of Girardot on the Magdalena River, it was downloaded and the contour lines were extracted to develop in ArcGIS the digital elevation model in 2D, that model was transferred to ArcScene, it was digitized in 3D as well as the image downloaded from the grid and the flood zone was calculated with the heights already established in HEC-RAS.
