Long-range climate forecasting water management Pacific Northwest region North America
2009/12/7
Ongoing research by the Climate Impacts Group at the University of Washington focuses on the use of recent advances in climate research to improve streamflow forecasts at seasonal-to-interannual, deca...
Extension of the measurement range of electrical conductivity by time-domain reflectometry (TDR)
electrical conductivity time-domain reflectometry
2009/6/8
The electrical conductivity (EC) of a medium invaded by TDR sensors can be estimated from the impedance of a TDR reflectogram. Four categories of sensor were tested in salt solutions and the impedance...

momentum roughness length canopy densities
2009/6/8
Values of the momentum roughness length, z0, and displacement height, d, derived from wind profiles and momentum flux measurements, are selected from the literature for a variety of sparse canopies. T...
Cascading model uncertainty from medium range weather forecasts (10 days) through a rainfall-runoff model to flood inundation predictions within the European Flood Forecasting System (EFFS)
Generalised Likelihood Uncertainty Estimation weather forecasts uropean Flood Forecasting System
2009/5/18
The political pressure on the scientific community to provide medium to long term flood forecasts has increased in the light of recent flooding events in Europe. Such demands can be met by a system co...
