Analysis of spatial variability of extreme rainfall events influenced by decadal oscillations in the Paute River Andean basin

Abstract:

Paute River basin is located in southern Ecuador, has an area of 5066 km2 and an elevation range of 1840-4680 m asl Its importance relay in different water uses as human consume for the city of Cuenca (near 400.000 inhabitants), irrigation, industry and an important hydropower plant for nearly 30% of the national system energy. Rainfall perturbations found in 1963-1993 period cause decadal oscillations of precipitation, which identifies the climate variability of the region. Positive perturbation belong to wet period and the negative belong to dry period, and between both there are transition periods. These oscillations seem to have influence of regional weather patterns such as ENSO. Consequently, the importance in knowledge of spatial and temporal variability of rainfall and it extremes is necessary for a better water resources management. Further, unimodal precipitation region (UM) with one yearly rainy …
