Assessing the sources of uncertainty associated with the calculation of rainfall kinetic energy and erosivity – application to the Upper Llobregat Basin, NE Spain
uncertainty associated calculation of rainfall erosivity – application
2011/3/15
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...
Evaluation of alternative formulae for calculation of surface temperature in snowmelt models using frequency analysis of temperature observations
alternative formulae surface temperature snowmelt models frequency analysis temperature observations
2010/4/7
The snow surface temperature is an important quantity in the snow energy balance, since it modulates the exchange of energy between the surface and the atmosphere as well as the conduction of energy i...
Calculation of time of concentration for hydrologic design and analysis using geographic information system vector objects
