The relation between rain movement and areal reduction of rain intensity is
investigated. An approach for calculating areal reduction factors from point
hyetographs and storm speed is suggested. Ver...
Spatial Variability of Soil Water and Evapotranspiration
Spatial Variability Soil Water Evapotranspiration
2009/10/27
Spatial variability in evapotranspiration from a crop covered field exposed to
homogeneous climatic conditions is partly caused by field variability in soil
physical properties and partly by field v...
While snowmelt and rain-on-snow events have received considerable attention
in rural watersheds they have been largely ignored in urban hydrology, despite
the fact that they may result in severe flo...
Swedish evaporation research has gone through a rapid development, and
there is now a need to overview the results. This review presents the research in
a broad sense. The brilliant research by Wall...
Effect of Climate Variability and Change in Groundwater in Europe
Climate Variability Groundwater in Europe
2009/10/26
Public water supply in Europe relies very heavily on groundwater. Recharge of
groundwater takes place mainly in the winter months. An analysis of winter
rainfall data shows that current recharge rat...

Climate Hydrology Vegetation Patterns Hot Weather
2009/10/26
Recent studies at Hot Weather Creek, Ellesmere Island document the climate
and vegetation of a major part of the intermontane zone of Ellesmere Island.
Summer temperatures in this region are much hi...
The Influence of Uncertainty in Air Temperature and Albedo on Snowmelt
Uncertainty Air Temperature Albedo on Snowmelt
2009/10/26
Extrapolating meteorological data to the basin scale represents a major problem
of spatial snowmelt modelling in alpine terrain. Within this study errors in
air temperature introduced by regionaliza...
Modelling the Effect of Climatic Warming on the Hofsjökull Ice Cap,Central Iceland
Climatic Warming Hofsjö kull Ice Cap Central Iceland
2009/10/26
A time-dependent cylindrically symmetric computer model of the Hofsjokull
ice cap, Central Iceland, has been defined in order to investigate the time-scale
of possible glacier variations. The model ...
Effect of Texture,Rainfall and Slope on Rainfall Interrill Sediment Transport
Texture Rainfall Slope Interrill Sediment Transport
2009/10/26
Experiments were conducted with rainfall intensities of 45.0 and 140.0 mmlhr
at slopes of 2, 9 and 20 per cent to separate the dominant effect of rainfall
intensity on sediment transport capacity. T...
Worldwide Testing of the Snowmelt Runoff Model with Applications for Predicting the Effects of Climate Change
Worldwide Testing Snowmelt Runoff Model Effects of Climate Change
2009/10/26
The Snowmelt-Runoff Model (SRM), a simple degree-day model, has been
applied to over 50 basins in 15 countries around the world. Where results have
been reported, the average R' has been 0.84 and th...
One of the most important consequences of future climate change may be an
alteration of the surface hydrological balance, including changes in flow regimes,
i.e. seasonal distribution of flow and es...
Sensitivity of Streamflow Simulation to Changes in Climatic Inputs
Streamflow Simulation Climatic Inputs
2009/10/26
Sensitivity of streamflow simulations to changes in temperature and precipitation
were evaluated for a small basin (A - 53 km2) characterized by low
evapotranspiration and high conversion of precipi...
Seasonal Variations in Suspended Sediment Yield in the Baltic Sea Drainage Basin
Seasonal Variations Suspended Sediment Yield Drainage Basin
2009/10/26
The aim of this article is to describe the seasonal fluctuations of suspended
sediment yield in the Baltic Sea drainage basin and to quantify the monthly
inflow of suspended sediment to the Baltic. ...
Suspended Sediment Yield in the Baltic Drainage Basin
Sediment Yield Baltic Drainage Basin
2009/10/26
The aim of this paper is to quantify the spatial distribution of suspended sediment
yield in the Baltic Sea drainage basin, and to quantify the suspended
sediment inflow to the Baltic. The sediment ...
Frequency of Extremes and its Relation to Climate Fluctuations
Frequency of Extremes Climate Fluctuations
2009/10/26
Possible consequences of climate change concern both changes in long-term
mean values of runoff and changes in frequency and magnitude of extreme
runoff events. The physical safety of dams and prote...
