The tide forms a boundary condition downstream in the estuary, which, synchronized with high discharges resulting from high amounts of precipitation, impedes the discharge of water, increasing the risk of flooding [4,16,17].
In Chile, years with ENSO have higher probability of precipitation; together with PDO, ENSO considerably affects snow accumulation and mountain flow regimes. The Andean mountains influence precipitation patterns across the country, affecting both temperature and precipitation.
13 sie 2020 · The hydrological cycle is expected to intensify with global warming, which likely increases the intensity of extreme precipitation events and the risk of flooding.
Explore the overview for a general context of how climate change is affecting Chile. This page presents a high-level insight into extreme events and how extreme events differ from mean climate. Extremes are often related to different physical processes than those that govern long-term means.
Floods, as part of the natural water cycle, have already posed a threat to early urban settlements and put at risk people, their assets and the ecological environment. Regularly occurring floods do also have a history in Santiago de Chile, the capital of Chile with approx. six million inhabitants.
Chile is recognized as vulnerable to climate change impacts, and overall, is ranked 29th out of 181 countries in the 2020 ND-GAIN Index. Within the Index, Chile is also ranked 22nd in terms of vulnerability and 36th in terms of readiness. The more vulnerable a country is the lower their score, while the more ready a country is to improve its
