The diverse sources of uncertainty associated with the calculation of rainfall kinetic energy and rainfall erosivity, calculated from precipitation data, were investigated at a range of temporal and s...
Quantifying uncertainty in urban flooding analysis considering hydro-climatic projection and urban development effects
Quantifying uncertainty urban flooding analysis hydro-climatic projection
2011/3/15
How will the combined impacts of land use change, climate change, and hydrologic modeling influence changes in urban flood frequency and what is the main uncertainty source of the results? Will such c...
Uncertainty in climate change impacts on water resources in the Rio Grande Basin, Brazil
Uncertainty in climate water resources Rio Grande Basin
2011/3/15
We quantify uncertainty in the impacts of climate change on the discharge of Rio Grande, a major tributary of the Paraná River in South America and one of the most important basins in Brazil for water...
Spatial uncertainty assessment in modelling reference evapotranspiration at regional scale
evapotranspiration regional scale
2010/12/22
Evapotranspiration is one of the major components of the water balance and has been identified as a key factor in hydrological modelling. For this reason, several methods have been developed to calcul...
Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity
soil hydraulic parameters performance two hydrological models different complexity
