Impact of global warming on aquifer-river interactions under groundwater intensive use: Mancha
Oriental Aquifer, Spain
Iordanka Dountcheva, David Sanz, Santiago Castaño and Juan José Gómez-Alday
University of Castilla – La Mancha., Spain
The Mancha Oriental System (MOS) is one of the largest aquifer within Spain (7,260 km2). MOS is located in the SE of Spain
and belongs to the Jucar River Basin. Since the 80’s, the exploitation of groundwater resources have become a key driver
for the socioeconomic development of the Castilla-La Mancha Region. Irrigation agriculture area currently exceeds 1,000
km2, and groundwater abstraction reached 314 Mm3/yr, from which 98% is used for irrigation. This figure contrasts with the
available groundwater resources estimated (265 Mm3) in the Jucar Hydrological Plan. Global warming effects on groundwater
resources have been masked by intensive use of groundwater. Coinciding with the launch expansión of the irrigated area,
regional temperature increased 2°C, not being able to establish a definite trend in relation to precipitation. However, the
temperature rise has caused a decline in aquifer recharge -18.9 Mm3/yr (compared to the full 1940-2010 period), which has
generated a loss in the aquifer storage and a reduction in the Jucar river base flow of about 1.1 Mm3/yr. So far these data have
not been taken into account in groundwater management measures tasks but should be crucial for a new hydrological planning
policy taking into account that global warming continues its current trend.
Biography
Iordanka Dountcheva has completed her master degree studies in 1997 from Technical University – Sofia, Bulgaria in Industrial Automation Engineering and
obtained the corresponding Spanish diploma from the Spanish Ministry of Education, Culture and Sports after complementary courses at the Politecnical
University – Valencia, Spain in 2013. Before starting her PhD studies in Hydrological Modelling with joint supervision from Technical University Sofia and the
University of Castilla-La Mancha, she has worked for the last 9 years in the private sector on Town Planning and Inftrastructural Projects Consultancy. She is
member of the College of Graduate and Industrial Technical Engineers of Albacete.
