DIAZ-GRANADOS ORTIZ, Mario A  y  CAMACHO BOTERO, Luis A. Assessment of Hydrologic Changes in the Bogotá River Basin. rev.ing. [online]. 2012, n.36, pp.77-85. ISSN 0121-4993.

In this article some refections are presented about hydrologic design related to extreme events, with some considerations regarding stationarity, and implications of the nonstationarity on hydrologic design. Some analyses are shown to illustrate hydrologic variations in the Bogotá river basin, using statistical tests for trends and step jumps in the mean, changes in soil uses and urbanization processes, sedimentation of streams in some reaches, and inclusión of macroclimatic phenomena in frequency analysis of maximum fows. Finally, some remarks are presented regarding the different natural and anthropogenic infuences that affect hydrologic systems. Likewise, it presents the need of historical data analysis with contextual supporting information, and the importance of incrementing hydrologic measurements, analysis and modeling in the Bogotá river basin.

Palabras clave : Bogotá river basin; hydrologic design; stationary.
