No âmbito do projeto MARSOL (http://www.marsol.eu/) foram realizados no Algarve diversos ensaios de gestão de recarga de aquíferos, com recurso a diferentes técnicas. Na presente comunicação apresentam-se os resultados de um desses ensaios, de injeção de água num poço, onde se colocou sal como traçador. Este ensaio foi monitorizado com recurso a perfis de resistividade elétrica e a sondas de registo contínuo da...
Water scarcity episodes are being experienced in many parts of the Mediterranean Basin as a result of changes in rainfall intensity and duration, causing more intense extreme events, like droughts and river floods. Adaptive and innovative water management strategies, such as the storage of reclaimed water or excess water from different sources in Managed Aquifer Recharge (MAR) schemes, can greatly increase the ...
Este artigo apresenta os resultados de um ensaio feito em escala de demonstração (DEMO) na Estação de Tratamento de Águas Residuais (ETAR) de S. Bartolomeu de Messines (SBM), onde foram construídos sistemas de tratamento em bacias (Soil-Aquifer Treatment, SAT, em nomenclatura anglo-saxónica). Os sistemas SAT visaram melhorar a qualidade do efluente tratado antes da sua descarga no ribeiro Meirinho, cujas águas ...
INTRODUCTION AND MAIN GOALS The main objectives of WP4 “DEMO Site 2: Algarve and Alentejo, South Portugal” are to demonstrate how MAR can contribute as an alternative source of water, in the context of an integrated and inter-annual water resources management, as well as in solving groundwater quality problems caused by previous agricultural practices and wastewater discharges. Three DEMO sites (Figure 1) have ...
The work progress of WP4 between month 19 and 27 was conducted with the strong collaboration of the three Portuguese partners (LNEC, TARH and UAlg) as well as with the regional water authorities (APA Algarve and APA Alentejo), the water supply company (AdA, Águas do Algarve), and the General Direction for Agriculture (DRAPALG), some of the main potential users of MAR. As reported before, the main purposes of th...
Neste Relatório de Atividades 6 e 7 apresentam-se os trabalhos desenvolvidos no âmbito da Atividade 6 – Elaboração do modelo hidrogeológico conceitual e modelo numérico, e da Atividade 7 – Ajuste, calibração e validação do modelo numérico, do Contrato n.º PSHPE 010/2014. A avaliação de consistência das séries de precipitação em 68 estações, num período de 30 anos, entre 1984 e 2013, permitiu identificar as esta...
Workpackage 12 deals with modelling MAR solution’s implementation. To study the effectiveness of these solutions, Task 12.5 was conceived and developed using physical models - which represent the real case study sites in a small and controlled scale - to demonstrate the effectiveness of MAR, namely clogging issues and physic-chemical treatment of recharging water. Besides the physico-chemical treatment, the exp...
A utilização de técnicas de MAR (managed aquifer recharge, em nomenclatura inglesa ou gestão de recarga induzida de aquíferos) visa armazenar água em aquíferos durante períodos de excedentes podendo ajudar a resolver posteriores desafios de escassez de água e, assim, melhor gerir a variabilidade temporal da disponibilidade de água. Além disso, a qualidade da água pode ser melhorada através da sua circulação pel...

The infiltration basin constructed in the GABARDINE project in Rio Seco stream (Algarve, Portugal) was rehabilitated during MARSOL project and a new infiltration test has been performed. The hydrogeological framework is presented and the new infiltration test is described and interpreted. The results are similar to those obtained during GABARDINE project, with calculated infiltration rates varying with water he...
