O código FREEWAT (FREE and open source software tools for WATer resource management) é um código aberto e gratuito que integra o código de modelação numérica de diferenças finitas MODFLOW (escoamento e transporte subterrâneo) ...

This paper deals with flow field and sediment flux measurements at alpine desanding facilities. 3D flow velocities and turbidity were recorded and water samples were taken at three alpine desanding facilities. The samples ...

Desanding facilities are located between the water intake and the penstock of medium and high-head hydroelectric power plants to avoid the entrance of suspended sediments into the penstock and therefore to reduce hydro-abrasion ...

As alterações climáticas causam impactos no ciclo hidrológico e nas disponibilidades hídricas, criando desafios adicionais à gestão integrada e sustentada dos recursos hídricos, nas suas componentes de qualidade, quantidade ...

A research project on laboratorial characterization of the breach processes involved in the failure by overtopping of earth dams is currently ongoing at LNEC and IST. The breach evolution process is a complex phenomenon ...

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 ...

A condição de fronteira Rio (“River”) dos modelos de diferenças finitas baseados no Modflow requer a caracterização, nem sempre fácil, de um conjunto de parâmetros. Neste artigo apresentam-se sugestões para a caracterização ...

The quantification of the breach hydrograph of an overtopped earth dam remains a challenge, even in controlled laboratory conditions. In this work, the breach hydrograph is calculated as the product of the velocity normal ...

The main goal of this study is the 3D numerical simulation of river flows with submerged vegetated floodplains. Since, vegetation layers are usually dense and present a large spatial heterogeneity they are here represented ...
