TL;DR: In this article, a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts is described. But despite the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work.

TL;DR: In this article, differences in groundwater samples from six groundwater bodies covered with different land uses were analyzed based on the monitoring plan of the Alqueva multi-purpose project, created in the sequence of the construction of the Guadiana River, in South Portugal.

TL;DR: The role of nitrate-contaminated groundwater discharge in the appearance of algal blooms in the Ria Formosa lagoon, south Portugal, is assessed by setting up a regional water balance for its drainage basin and determining annual N loads on groundwater.

TL;DR: In this article, a geostatistical methodology is developed with the aim of simulating three-dimensional grids of transmissivity, which is applied to a case study of a highly heterogeneous massif rock body, mainly composed of granites and schists with distinct weathering and fracture conditions, that surrounds and is part of a former uranium mine in central Portugal.

TL;DR: Carvalho gave his last lecture at the School of Engineering of Polytechnic of Porto in January 2014, bringing to a formal close an outstanding career in multidisciplinary hydrogeology teaching and practice (in Europe, Africa, Middle-East, Asia, South America) and in applied research as discussed by the authors.
