Abstract | The increasing evidence of climate change motivates the need of quantifying its impacts on groundwater resources and their associated ecosystems to minimize its negative effects. Climate change is expected to produce an increase in temperature and a decrease in precipitation in many places of the Iberian Peninsula. These changes will reduce the groundwater resources. The rise of the sea level in coastal aquifers is an additional threat to groundwater resources. The effects of climate change in the groundwater resources of the Plana de La Galera and Tortosa alluvial aquifers near the Ebre River Delta have been evaluated with water balance and groundwater flow models and three regional climate models by taking into account simultaneously the reduction of groundwater recharge and the rising of the Mediterranean Sea level. The models were calibrated with historic data from 1998 to 2008 and then used to simulate the impacts of climate change in groundwater levels in the simulation periods 2020–2050 and 2069–2099. The climate models predict an increase in average temperature and a decrease in rainfall in the simulation periods 2020–2050 and 2069–2099 compared to the control period 1960–1990. Consequently, the mean annual recharge in the Plana de La Galera aquifer will decrease 23 % in the period 2020–2050 and 27 % in the period 2069–2099 compared to the mean annual recharge in the control period 1960–1990. The recharge in the Tortosa alluvial aquifer will decrease 22 % in the period 2020–2050 and 31 % in the period 2069–2099. The predicted changes in recharge vary significantly from rain-fed to irrigated (drip and flood) areas. In rain-fed areas, the decrease in groundwater recharge is approximately equal to the decrease in precipitation. According to the models here developed, the reduction in recharge will lead to a significant lowering of hydraulic heads in the recharge areas of the Plana de La Galera aquifer for the period 2069–2099. Near the Ebre River Delta, however, groundwater heads will increase slightly due to the rise of the mean sea level. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
