Annual extreme rainfall series of 1-3 day durations at stations located inside the Indus basin in India were subjected to statistical analysis in order to estimate point Probable Maximum Precipitation...
Rainfall-Runoff Modeling for an Experimental Watershed of Western Greece Using Extended Time-Area Method and GIS
Rainfall-runoff modeling Forested watershed Time-area method
2015/1/6
In this study, an effort was made to simulate the transformation of rainfall into runoff, in a small experimental mountainous-forested watershed in western Greece. The main objective was the productio...
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...
Spatial interpolation of hourly rainfall – effect of additional information, variogram inference and storm properties
Spatial interpolation hourly rainfall additional information variogram inference
2011/3/15
Hydrological modelling of floods relies on precipitation data with a high resolution in space and time. A reliable spatial representation of short time step rainfall is often difficult to achieve due ...

Areal Intensity-Duration-Frequency Curves for Short Term Rainfall Events in Lund
Areal Intensity-Duration-Frequency Curves Short Term Rainfall Events
2009/10/28
Design Storms, which are usually derived from point intensity-durationfrequency
(i-d-f) relationships, neither reflect the areal variations of the rainfall
pattern nor the dynamics of the moving sto...

Excess Rainfall Time Catchment Area Hydrograph
2009/10/27
The effect of triangular excess hyetographs on catchment area runoff process is
investigated, thereby fixing the precipitation time. The approach accounts for
the kinematic wave theory and allows a ...
