Estimación de ecuaciones de transferencia hidrológica para el cálculo de caudales en la Cuenca Baja del Río Magdalena.

Abstract

The princial objective of this work is estimate magdalena´s river lower watershed the necessary and appropiate equations to calculate flows in the non-measured station from measured hydrologic stations information by the transfer flows method. Initially, the measured station must have sufficient information as flow and drainage area. This information will be get through the Instituto de Hidrologia, Meteorologia y Estudios ambientales de Colombia (IDEAM), besides of existing literature and investigations on the subject. Also, in this work is necessary to guarantee that the selected stations are into homogeneous subregions hydrologically and they have similar characteristics in terms of the hydrological environment, such as topography, vegetation type, soil type, geology, besides it consider the relationship between drainage area and flow to get lowest possible variability in the data. Knowing and ensuring previously, in this work will be used the statistical regression method to obtain the flow transfer equations, which results will be proved with cross-validation. If as result of this comparison, the difference between the theoretical and observed data is minimal, the found equations will consider correct and will be select the most suitable equation. From the equations raised and with reference to the procedures described in the Journal of the American Water Resources Association, who need it, you can without any problem to calculate unmeasured flow in the lower basin of the Magdalena River stations.
