Abstract(s) :

(Anglais) Despite the abundance of natural water resources, urban areas of Latin America and the Caribbean (LAC) countries are facing shortcomings in the delivery of basic services such as safe water supply, while also being affected by floods during the raining season. The cause is manifold and includes the spatial and temporal heterogeneity of water resources, the negative water balance caused by overexploitation, and the insufficient human capacities and governance. In this context, managed aquifer recharge (MAR) is proposed for enhancing traditional water infrastructure with nature‐inspired solutions that allow for a more equitable water provisioning. DIGIRES (“Digitally‐enabled green infrastructure for sustainable water resources management in Latin America and the Caribbean (DIGIRES)” is an international collaboration project funded through the ERANet‐LAC 3rd Multi‐Thematic Joint Call 2017/2018 by funding agencies from Germany, Belgium, Brazil, Guatemala and Cuba. The project aims at the development and utilisation of information and communication technology (ICT) tools for planning of MAR schemes as potential solution for sustainable water resources management in LAC region. The work includes the development of numerical groundwater flow models that are expected to support the understanding and prediction of the processes occurring at MAR sites. The models have mainly demonstrative character and aim primarily at showing the benefits of MAR at locations in the participating countries, as well as the usability of advanced ICT systems for the evaluation of MAR projects at different implementation stages. For the groundwater simulations, the project team uses the free groundwater modelling platform developed by the INOWAS research group at TU Dresden (www.inowas.com). The INOWAS platform contains a collection of web‐based simulation tools of different complexities for the simulation of groundwater processes related to MAR. This presentation introduces the development of a MODFLOW‐based numerical model and its application for the simulation of different recharge and management scenarios at a potential MAR site in Recife, Brazil.
