Desarrollo del catastro, creación del modelo hidráulico y diagnóstico de la red de alcantarillado en la zona central de Pamplona – Norte de Santander.

Abstract

Due to the fact that Pamplona has had a considerable growth in the last years in its population and student community, it was necessary to obtain the information of the updated cadastre of the sewerage networks in the central area of Pamplona. It is necessary to model the sewerage networks in the EPA SWMM software, to have better information of the conditions of the sewerage system and the service capacity at the moment of evaluating a hydraulic model. For this reason, the sewerage network cadastre was updated and the polygon of the central area of Pamplona was delimited by means of Google Earth, where the topographic survey was carried out implementing drone flight, then a photogrammetry was generated, where the images were imported to Agisoft Metashape to create the multiclass points generating the DEM and the orthomosaic of the central area of Pamplona, Then a detailed plan was made in AutoCAD with all the information of the cadastral survey and consecutively the management of the QGIS software for the import of the orthophoto, where a georeferencing was generated to the orthophoto, collectors and their respective inspection wells, in which the coordinate reference system was implemented (Colombia, Bogota - EPSG: 3116) for its respective export to SWMM. Where its hydraulic modeling of the sewerage system was performed.
