Fig. 8.12 Number of days by month when Rapel dam gates were opened, allowing the supply of
sediment to the beach of El Yali wetland. ENOS 3.4 index is also shown and it is observed that,
especially in the past century, there used to be a correlation between the opening of the dam gates
and the index that indicates the anomalous increase of temperature in the 5°N–5°S, 120°–170° W
