Analyzing green behavior and the rational use of water in Portuguese higher edu...
Barreiros, Ana M.; Durão, Anabela; Galvão, Ana; Matos, Cristina; Mateus, Dina; Araújo, Ivo; Neves, Luís; Matos, Mário; Mourato, SandraIn the forthcoming years Portugal expects to be an increasingly hot and dry country dealing with the risk of water scarcity. According to the Portuguese Institute for Sea and Atmosphere data, annual precipitation values have decreased 20 mm/decade. On the other hand, it is also verified that the periods of rain occur in a shorter interval, although more intensively. Water scarcity is one of the major challenges...

Recurso ao focus group para identificação de perceções sobre riscos naturais
Veiga, Anabela; Mourato, Sandra; Anastácio, R.F.; Quinta-Nova, L.C.The aim of this article is to present the results obtained through the application of the Focus Group technique as part of a process of public participation and involvement of the local community of the municipalities of Leiria, Ferreira do Zêzere and Ourém within the Project CLIMRisk - “Climate change adaptation measures in the management of natural and environmental risks”. The methodology used consisted of d...
An interactive Web-GIS fluvial flood forecast and alert system in operation in ...
Mourato, Sandra; Fernandez, P.; Marques, Fábio; Rocha, Alfredo; Pereira, LuísaFloods are one of the natural disasters not preventable, affecting people and causing significant damage to economic activities and infrastructures. Thus, it is of foremost importance to, within a disaster risk-reduction strategy, develop a useful flood forecast and alert system to prevent people from suffering flood disasters and mitigate its consequences. This article presents the Flood Forecast and Alert Sys...
Quality control of outsourced LiDAR data acquired with a UAV : a case study
Pereira, Luísa Gomes; Fernandez, P.; Mourato, Sandra; Matos, Jorge; Mayer, Cedric; Marques, FábioOver the last few decades, we witnessed a revolution in acquiring very high resolution and accurate geo-information. One of the reasons was the advances in photonics and LiDAR, which had a remarkable impact in applications requiring information with high accuracy and/or elevated completeness, such as flood modelling, forestry, construction, and mining. Also, miniaturization within electronics played an importan...

Downscaling climate change of water availability, sediment yield and extreme ev...
Zhang, Rong; Corte-Real, João; Moreira, Madalena; Kilsby, Chris; Birkinshaw, Stephen; Burton, Aidan; Fowler, Hayley J.; Forsythe, NathanA robust hydrological impact assessment is indispensable for mitigation and adaptation planning. This study presents an integrated modelling methodology for evaluating climate change impacts on water availability, sediment yield and extreme events at the catchment scale. We propose the use of the spatial–temporal Neyman–Scott Rectangular Pulses (STNSRP) model—RainSim V3 and the rainfall conditioned daily weathe...
A Generalized Dynamic Programming Modelling Approach for Integrated Reservoir O...
Rani, Deepti; Mourato, Sandra; Moreira, MadalenaIn water resource systems, the demands at each reservoir are generally known. However, in the integrated operation of a system involving inter-basin water transfers, the import/export of water among various reservoirs also plays an important role in the sustainable and optimal management of available water. Generally, a trial and error approach is adopted to simulate a system for integrated operation. Prior inf...
Recurso ao Focus Group para identificação de perceções sobre riscos naturais
Veiga, Anabela; Anastácio, R.F.; Mourato, Sandra; Quinta-Nova, L.C.A utilização da técnica do focus group (FG) tem vindo a alargar o seu campo de aplicação a diferentes áreas do conhecimento, como é o caso da prevenção de riscos naturais. Consiste numa técnica de recolha de dados através da interação de um grupo baseada num tópico apresentado por um moderador. este método comporta três componentes essenciais: permite a recolha de dados; localiza a interação na discussão do gru...
Geostatistical analysis of settlements induced by liquefaction: case study rive...
Veiga, Anabela; Mourato, Sandra; Rodrigues, HugoIn the present work the result of the application of geostatistical methods to soil settlement data is presented. The settlements are induced by liquefaction as a result of an earthquake of magnitude 5.5. In the present paper the ArcGIS Geostatistical Analyst software was used, where a number of Kriging methods are available. Geostatistical analysis was performed on two phases: (i) modelling the semivariogram t...
