Abstract The analysis of extreme wave conditions is crucial for understanding and mitigating coastal hazards. As global reanalyses allow to extend the evaluation periods locations not covered by in-situ measurements, their direct use common. However, in areas, accuracy lower, particularly waves. Here we compare two leading against 326 buoys, demonstrating that both consistently underestimate significant height, 50-year return period mean most around world. Different calibration methods...
An experimental burning program took place in maritime pine (Pinus pinaster Ait.) stands Portugal to increase the understanding of surface fire behaviour under mild weather. The spread rate and flame geometry forward backward sections a line-ignited front were measured 94 plots 10–15 m wide. Measured head spread, length Byram’s intensity varied respectively intervals 0.3–13.9 min–1, 0.1–4.2 30–3527 kW m–1. Fire was modelled through an empirical approach. Rate described as function wind...
The relative influence of the factors acting on burn probability, namely fuel and weather, is not well understood, especially in Europe. We use a digital fire atlas (1975–2008) apply survival analysis to individual fires (1998–2008) describe how probability changes with age Portugal. typical return interval median fire-free vary regionally from 23 52 18 47 years. Increase hazard burning time generally near-linear, denoting moderate fuel-age dependency, as some other shrub-dominated...
During the 2017 wildfire season in Portugal, unprecedented episodes burned 6% of country’s area and underscored need for a long-term comprehensive solution to mitigate future disasters. In this study, we built calibrated national-scale fire simulation system including underlying fuels weather data used quantify exposure communities natural areas. We simulated 10,000 replicates under extreme generate 1.6 million large perimeters estimate annual burn probability intensity at 100 m pixel...
Thresholds for surface fire spread were examined in maritime pine ( Pinus pinaster Ait.) stands northern Portugal. Fire sustainability was assessed after ignition of 2 m lines or larger burns conducted 10–15 wide plots. The experiments carried out from November to June three fuel types: litter, litter plus shrubs, and with a nonwoody understorey. Moisture content fine dead fuels, on-site weather variables, descriptors the complex all had highly significant influence on probability...
Maritime pine (Pinus pinaster Ait.) stands are prone to high-intensity fire. Fuel treatments lessen potential fire behaviour and severity, but evidence of their effectiveness when tested by wildfire is extremely scarce in Europe. We assess the longevity prescribed burning maritime plantations decreasing severity. Heights crown scorch stem-bark char were measured treated untreated adjacent areas after fire-treatment encounters Portugal, Italy, Australia. Treatment effect was quantified as...
In northern Europe, beach erosion, coastal flooding and associated damages to engineering structures are linked mid-latitude storms that form through cyclogenesis post-tropical cyclones, when a tropical cyclone moves north from its origin. The present work analyses the hydrodynamic forcing morphological changes observed at three beaches in coast of Northern Ireland (Magilligan, Portrush West’s southern sectors, Whiterocks), prior to, during, immediately after Katia. Katia was second major...
Satellite imagery is crucial for studying shoreline evolution due to its ability provide consistent, high-resolution, and large-scale data over time (Gomes da Silva et al., 2024); it plays a role in countries with limited coastal information sources. The aim of this study explore the use satellite investigate at three different locations Mozambique: Morrungulo Beach, Barra Tofo Beach Inhambane Province. These are characterized as exposed mesotidal beaches were selected representative typical...
Abstract Contemporary shoreline change is driven by a complex combination of factors, and as such often highly variable along the coast. While differences in beach morphology can explain some variability change, geological constraints imposed coastal geology are overlooked. This work examines influence foreshore configurations with varying degrees non‐dynamic control, which analysed hydrodynamic forcing to investigate seasonal multiannual evolution five barriers Outer Hebrides, Western...
Coastal storms can promote damaging impacts on barrier islands, induced by coastal flooding and beach erosion (Leaman et al., 2021). Process-based morphodynamic models, implemented with high- resolution topo-bathymetric oceanographic data, enable the assessment of these hazards at regional local scales development early warning systems. The advent global models to characterise wave forcing (global reanalyses) topo-bathymetry digital elevation DEM) allows quantification storm be extended...
