| Sumario: | Climate change and the management of water resources are elements that impact the availability of water in the territories. This work analyzes the behavior of the pluviometric and fluviometric variabilities in the Maule river basin, Chile, one of themain and largest at the national level with an area corresponding to 20,300 km2, and where silvo-agricultural activity predominates. A cluster analysis was performed based on the data available for rainfall (period 2000-2019) and flows (period 2003-2019)whose link between the latter and the former is associated with the magnitude of runoff. The behavior of these shows that an attention to the decrease, presumably due to the mega drought and variations in the mesoscale climatic behavior. The dataanalysis allows us to suppose a relationship between the rainfall behavior and the decrease in the average flow of channels and rivers, causing negative consequences to the socio-economic activities related to the use of water and demanding new formsof water management in the territories. |
