Given its

geographic

location, the

Guadalquivir

basin is very

vulnerable to

changes in

atmospheric

circulation.

In the last

decades some

changes have

been observed in

basin rainfall

Trends in last fifty years: rain (13 reservoirs,

distributed along the whole basin)

In the last 50 years the average rainfall hasn’t changed

very much, but not-average years are more frequents

Trends in last fifty years: rain (13 reservoirs,

Rainfall year distribution: 1967/1992 vs 1993/2017

• Also the yearly distribution in changing, been more

“mediterranean” and les “atlantic”; more rainfall in

Let’s see what’s happening at the atlantic coast.

We are going to compare the 1984/1999 and 2000/2015 periods

Average increasing is not big: average 2000/2015 year

is “only” 0,2ºC hotter than the 1984/1999 one

Agreements with other corporations

CHG have specific agreements with

several scientific and academic

institutions in order to improve water

management in a changing scenario

We can highlight the design & use of

International Agreements for dealing

with climate change.

The spanish water administration is present

in several specific agreements related with

climate change.

Among them we could highlight:
