Source Documents for Andalucia Water Supply research

Source documents for our Water Supply in Andalucia research ranging from the Andalucia Government Budgets, hydrological and drought monthly and annual reports. Three cycles of five year plans for each of the water basins, special plans for the drought.

Annual reports on Hydrological year in Andalucia - Informe Balance Año Hidrological
The six-page annual reports on Hydrological year in Andalucia for years 2008/9 to 2014/2015 can be downloaded from Portal Ambiental de Andalucía. There are no reports published after 2014/2015. Monthly reports were only published from October 2009 to February 2012.

It looks like the Hydrological reports were replaced by the drought reports in 2016. A drought report is different from a water shortage report. It looks at current rainfall against historic rainfall and predict probable time to return to normal. It is probably of more interest to a farmer than for hydrological research.

The Standardised Rainfall Drought Index evaluates accumulated rainfall anomalies relative to the median on a monthly basis. It is therefore a good indicator of the duration and intensity of periods of rainfall deficit. Its dimensionless nature means that, for its interpretation, categories have been established according to the distribution of rainfall as a function of its values depending on their correspondence to certain return periods of return periods of 3.33 years (moderate drought), 7 years (severe drought), 20 years (exceptional drought) and 50 years (exceptional drought).

Monthly analysis of the drought in Andalucia. A sub-provincial study. - Análisis de la sequía en Andalucía.
Synthetic values are obtained to measure the incidence of drought by agricultural region (similar to Comarcas) based on the study of precipitation and vegetation stress. Forecasts are made for the coming months.

It also produces a five traffic light system for each Comarca in Andalucia. Again this is more measure of drought in the meteological sense and not drought in the water shortage sense.

 

Status	Description	Action
Normal	There is no rainfall shortage	It is not necessary to take short-term measures.
Moderate	Return period of 3.33 years
Severe	Return period 7 years.	Severe shortages include a clear risk of not being able to meet demand.
Extraordinary	Return Period 20 years.
Exceptional	Return Period 20 years	Grave.

Reports from September 2016 to about six weeks ago can be downloaded.

Andalucia Government Budgets
Andalucia Government Budgets are complex series of documents published at the end of each year for the following year's budget. They do contain a small sections on water management.

Four special Andalucia decree Laws to alleviate the effects of the exceptional drought

Decree-Law 2/2024 of 29 January, approving additional measures to alleviate the effects of the exceptional drought situation on users of the intra-community hydrographic demarcations of Andalusia and adopting urgent administrative and fiscal measures to support the agricultural sector.
Fourth Andalucia drought decree-law. Regional Government approved the fourth drought decree-law with a budget of 200 million euros. 50 million euros will be earmarked for measures to help the agri-food sector. Emergency works include Jerez de la Frontera (Cádiz), Bajo Guadalhorce and Antequera (Málaga) and Motril (Granada). The improvement of water supply in Axarquia, with the Trapiche Drinking Water Treatment Plant; the Fuengirola and Río de Guadalmansa boreholes, portable desalination plants, and the Guadarranque canal boreholes. Water storage tanks in the Almanzora Valley (Almeria); improved storage in Santa Olalla del Cala and the villages of Cueva del Moral, Monteblanco, and Almonaster la Real (Huelva), and a floating intake (for near-surface water) on the Guadarranque reservior. The decree's foresees an investment of 30 million euros in the following infrastructures: In the Corumbel System (Condado pipeline in Huelva); in the Barbate System (supply pipeline to Tarifa (Cadiz); in the Campo de Gibraltar System (Pinar del Rey wells, supply to the northern area of San Roque, Guadiaro and El Tesorillo reservoirs, and wells on the Guadiaro river); Viñuela-La Axarquía System (La Rosaleda pumping, Guadalhorce-Limonero and Axarquía System, and El Atabal) and in the Cuevas de Almanzora System.

Decree-Law 3/2023 of 25 April, approving additional measures to alleviate the effects of the exceptional drought situation on users of the intra-community water districts of Andalucia and adopting urgent administrative and fiscal measures to support the agricultural sector.

Decree-Law 2/2022 of 29 March extending the urgent measures to alleviate the effects produced by the exceptional drought situation in the intra-community hydrographic demarcations of Andalucia, and adopting urgent administrative and fiscal measures to support the agricultural and fisheries sector.

Nine Hydrographic Confederations in Spain – Three covering Andalucia

There are nine Hydrographic Confederations in Spain, of which one Confederación Hidrográfica del Guadalquivir covers most of Andalucia and a little of its neighbouring regions. Since the River Guadiana is the border between southern Spain and Portugal, the Confederación Hidrográfica del Guadiana includes the western part of Huelva province and also Extramadura. There is also a very small part of the Confederation Hydraulica de Segura in eastern Andalucia.  

 

Three Andalucia Coastal Zones

These Hidrographic demarcations are wholly located in Andalucia and therefor are agencies responsible to the Junta de Andalucia – Consejería de Sostenibilidad, Medio Ambiente and Economia Azul (Regional government environment department) rather than the national government.

Along the Mediterranean and Atlantic coasts of Spain rainwater flows away from the watersheds of the Confederations Hidrogtaficas down towards the to the coast. In Andalucia these are divided into three zones; two Atlantic Ocean and one Mediterranean Sea:
