Construcción del modelo conceptual de la avenida libertadores entre la calle 8 norte y la avenida 2 de la ciudad de Cúcuta, Norte de Santander, para la simulación de la lluvia en el SWMM

Abstract

The objective of the research was to build the conceptual model from Avenida Guaimaral to Avenida Libertadores between Calle 8 Norte and Avenida 3 in the city of Cúcuta, Norte de Santander. Initially, a spatial recognition of the basin selected as a case study was carried out through the help of a geographic information system (GIS) and a digital elevation model (DEM) downloaded from a free source, the delimitation was obtained with a slope raster of the basin, knowing the possible contributions upstream of the area. Subsequently, field visits were made to verify the tributary areas to the basin, the existing drainage network and the streets or paths that serve as a means of transporting surface runoff to produce rainwater were also identified in situ. land use and important points where changes in permeable and impermeable zones occur. Similarly, the cadastral and cartographic information of the study area was collected, requested from public entities and government entities in charge of the rainwater evacuation systems. Finally, with a supervised and unsupervised classification, the permeable and impervious zones were discretized in order to know the percentage of these areas and once the areas of the sub- basin were known, the data required to determine the geomorphological parameters was loaded, in order to obtain the conceptual model.
