Estimación de caudales medios por subcuencas pertenecientes a la cuenca del río Pamplonita, Norte de Santander, mediante la herramienta de simulación del recurso hídrico Hydro-BID.

Abstract

This project proposes the obtaining of average flows by sub-basins of the Pamplonita River under hydrological simulation scenarios under normal conditions, implementing the Hydro-BID hydrological modeling tool. Initially, to obtain input inputs for the model, the variables of temperature, precipitation and flow, from climatic and hydrological stations installed in the study basin, were downloaded from IDEAM's dhime platform. The climatic data were adjusted using the arithmetic mean methods and normal proportions, being validated by means of the double mass curve and the R2 parameter, as for the flow data they were adjusted using the online Matlab program, applying the grade 8 polynomial model. for the data of the station 16017010, and polynomial model of degree 6 for the station 16017020, verifying its efficiency and reliability through the parameter of R2. For the delimitation and generation of COMID and centroids of the basin, the QGIS program and the AHD database were used. The calibration of the model was carried out using the database of flows obtained from the IDEAM platform where, through a series of iterations, the hydrological parameters of the model were adjusted until obtaining adequate performance statistics, which were subsequently validated, obtaining optimal performance indexes as results, especially for monthly data. Finally, the mean flows and the flow rate per area were obtained for each of the sub-basins.
