Prediction of rain cell growth and decay using numerical weather prediction models

Radar rainfall nowcasting stands for the prediction of rainfall amounts and intensities over the next 6 hours by means of statistical extrapolation of radar measurements. It is the principal ingredient for modern flood forecasting and early warning systems. Radar forecasts are generated by identifying and tracking rainfall cells in radar images...

Inferring catchment precipitation by doing hydrology backward: A test in 24 small and mesoscale catchments in Luxembourg

The complexity of hydrological systems and the necessary simplification of models describing these systems remain major challenges in hydrological modeling. Kirchner's (2009) approach of inferring rainfall and evaporation from discharge fluctuations by “doing hydrology backward” is based on the assumption that catchment behavior can be...

A resonating rainfall and evaporation recorder

We propose a novel, accurate quantification of precipitation and evaporation, as needed to understand fundamental hydrologic processes. Our system uses a collection vessel placed on top of a slender rod that is securely fixed at its base. As the vessel is deflected, either by manual perturbation or ambient forcing (for example, wind), its...

Rainfall generator for the Meuse basin; Development of a multi-site extension for the entire drainage area

A stochastic weather generator is constructed to simulate long series of precipitation and temperature for the Belgian and French Meuse basin. This weather generator is based on the principle of nearest-neighbour resampling, a method which samples daily data from a historic record with replacement such that the temporal and spatial correlations...

Development of conceptual rainfall-runoff models for the personal computer

Nowadays, the development in the personal computer hardware and software is very fast. It is more and more applicable with its recursive calculation character in hydrological modelling. By applying system analysis and system synthesis, it becomes a fashion in hydrological modelling to use the conceptual models instead of black-box models. This...
