ERA5-Land Reanalysis Temperature Data Addressing Heatwaves in Portugal
In this research, heatwaves in Portugal were analysed using high-resolution daily minimum and maximum temperature data (Tmin and Tmax) from the European Reanalysis of Global Climate Observations (ERA5-Land) fo...

Rainfall trends over a North Atlantic small island in the period 1937/1938–2016/2017 and an early climate teleconnection
Changes in the rainfall amounts in a small island in the North Atlantic Ocean—Madeira Island—were analysed based on complete daily rainfall series aggregated into 1-, 3-, 6- and 12-month rainfall and annual ma...

Rainfall Trends over a Small Island Teleconnected to the North Atlantic Oscillation - the Case of Madeira Island, Portugal
For improving sustainable water resources management and planning at local and regional scales, specifically in small islands, long-term and recent rainfall trends due to temporal shifts in major climatic driv...

Rainfall Trends in Southern Portugal at Different Time Scales
The evidence about the climate change is now considered to be unequivocal. But if visible changes are occurring at an increased rate over shorter periods, then the time series of the hydrologic variables more...

Using Climate-Flood Links and CMIP5 Projections to Assess Flood Design Levels Under Climate Change Scenarios: A Case Study in Southern Brazil
The Intergovernmental Panel on Climate Change (IPCC) assessed with medium confidence that there has been an anthropogenic influence in the intensification of heavy rainfall at the global scale. Nevertheless, w...

A Bayesian peaks-over-threshold analysis of floods in the Itajaí-açu River under stationarity and nonstationarity
In this paper we revisit the case study of Silva et al. (Stoch Env Res Risk A. doi:10.1007/s00477-015-1072-y, 2015), the Itajaí-açu River at Apiúna (Southern Brazil), with an augmented data set and Bayesian infer...

Disaggregation Modelling of Annual Flows into Daily Streamflows Using a New Approach of the Method of Fragments
For many decades, synthetic streamflow series have been utilized in hydrology to analyze numerous stochastic problems whose solutions depend on the values of the streamflows and their temporal pattern. The sto...

On some aspects of peaks-over-threshold modeling of floods under nonstationarity using climate covariates
This paper discusses some aspects of flood frequency analysis using the peaks-over-threshold model with Poisson arrivals and generalized Pareto (GP) distributed peak magnitudes under nonstationarity, using cli...

SPI Modes of Drought Spatial and Temporal Variability in Portugal: Comparing Observations, PT02 and GPCC Gridded Datasets
Regional drought modes in Portugal are identified applying the Principal Component Analysis (PCA) and Varimax rotation to the Standardized Precipitation Index (SPI) computed on various time scales using the th...

On peaks-over-threshold modeling of floods with zero-inflated Poisson arrivals under stationarity and nonstationarity
The peaks-over-threshold (POT) model with Poisson arrivals and generalized Pareto (GP) distributed exceedances remains a popular and useful tool for modelling hydrologic extremes. The use of the Poisson–GP mod...

Analysis of Temporal Variability of Droughts in Southern Paraguay and Northern Argentina (1961–2011)
The study presents an analysis of droughts using monthly rainfall data, from January 1961 to December 2011, from 11 rain gauges located in Paraguay and Northern Argentina. The characterization of the drought e...

Investigation on the properties of the relationship between rare and extreme rainfall and flood volumes, under some distributional restrictions
The fact that rainfall data are usually more abundant and more readily regionalized than streamflow data has motivated hydrologists to conceive methods that incorporate the hydrometeorologial information into ...

Regional Frequency Analysis of Droughts in Portugal
This study investigated the frequency of droughts for the period September 1910 to October 2004 in mainland Portugal, based on monthly precipitation data from 144 rain gauges distributed across the country. Th...

Open AccessThe challenge and status of IWRM in four river basins in Europe and Asia
This paper assesses the implementation of four selected IWRM principles in four very different river basins in Europe and Asia. The four principles relate to all the different aspects of sustainable developmen...
