Design and characterisation of customised-roughness beds for open-channel flow ...
Isidoro, Jorge; Martins, Ricardo; Pereira, Luísa Gomes; de Lima, João L.M.P.The use of laboratory channels or flumes for open-channel flow research is widespread. However, this type of equipment is often expensive, susceptible to damage, and require regular maintenance. In open-channel flow, the roughness of the channel bed is a critical property in governing the flow characteristics. Unfortunately, changing the bed properties, particularly its roughness, proves to be a challenging and...
Quality control of outsourced LiDAR data acquired with a UAV : a case study
Pereira, Luísa Gomes; Fernandez, Paulo; 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...
An interactive Web-GIS fluvial flood forecast and alert system in operation in ...
Mourato, Sandra; Fernandez, Paulo; Marques, Fábio; Rocha, Alfredo; Pereira, Luísa GomesFloods 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...

Planning and acquisition of control data to validate forest inventory and the e...
Tomé, Margarida; Pereira, Luísa Gomes; Gonçalves, Gil; Soares, Paula; Cambra, Sílvia; Carvalho, SérgioThe estimation of forest and fuel variables by using LiDAR data and CIR high-resolution images is the main objective of the project PTDC/AGR-CFL/72380/2006 financed by the Portuguese foundation Fundação para a Ciência e Tecnologia (FCT). To estimate those variables a novel software system needs to be developed and tested. To this end, control data are necessary. In this article it is addressed the planning and ...
