In the Algarve southern Portugal region, Managed Aquifer Recharge (MAR) research activities have been developed to provide not only water surplus storage in aquifers during wet years, focusing in the Querença-Silves aquifer ...

In recent decades the groundwater overexploitation and unabated use has led to severe environmental problems such as resource depletion, land subsidence and seawater intrusion in coastal areas. Globally, climate change is ...

Este relatório apresenta os resultados da monitorização do nível piezométrico e da qualidade das águas subterrâneas efetuada nos furos e nos poços localizados no interior do perímetro do campus do LNEC, bem como dos ...

In Europe, numerous urban sites exist where top layers of soil are enriched in potentially toxic elements. The land uses in urban environment are a matter of concern for human health and food security in cities, also in ...

A previsão rigorosa da profundidade de cavidades de erosão associadas a pilares complexos, utilizados como apoio de tabuleiros de pontes, pode não ser garantida pela utilização dos métodos actualmente existentes. De entre ...

The longitudinal development of compound channel flow and the corresponding mixing and boundary layers are investigated. An experimental campaign was carried out in a laboratory compound channel. Six uniform flows were ...

The paper summarizes recent contributions of the authors on the effects of relative flow depth, relative sand size, time and fluid viscosity, on the scour depth at single piers. These contributions rely on unique experiments ...

Dam overtopping is one of the major causes for the failure of earth dams. The objectives of the present paper are the characterization of the breach evolution and the quantification of the breach hydrograph caused by dam ...
