Resumen
En este trabajo se identificaron tendencias significativas en la mayoría se las series de precipitación, caudal, evapotranspiración real y humedad del suelo analizadas en sub-cuencas de las cuenca Amazónica. Algunas variables presentan tendencias mezcladas, los caudales presentan tendencias crecientes generalizadas y la humedad del suelo tendencia decreciente generalizada. Las señales detectadas no parecen estar directamente relacionadas con las pérdidas de bosque, pero si con las variabilidad hidro-climática o cambio climático. En general las series son homogéneas con algunas excepciones. Las tendencias encontradas contradicen la hipótesis de estacionariedad esta puede ser una de las causas por la cual la ecuación de balance hídrico no se cumple.
Abstract: In this thesis, long-term trends were identified in most of the series of precipitation, flow, real evapotranspiration and soil moisture analysed in sub-basins of the Amazon basin. Some variables have mixed trends, but the flows present generalized increasing trends and soil moisture generalized decreasing trends. The signals detected do not appear to be directly related to forest losses, but to hydro-climatic variability or climate change. In addition, we found that the series are homogeneous with some exceptions. The trends found contradict the hypothesis of stationary this may be one of the causes for which the water balances equation is not applicable.
