Since 1980, the Hydraulics Laboratory of the State University of Ghent has been responsible for control and maintenance of the gauging stations, the stage-discharge measurements and the collection, the processing and the publication of the data
Aggregation and ecological effects in geographically baseddata
in the analysis of individual-level data can be magnified when the analysis based on aggregated data is carried out. The models provide an approach to the problem of adjusting an area-level analysis to correct for aggregation effects. The data come from the 1991

Evaluating soil erosion models using measured plot data : accounting for variability in the data
The objective of this study was to construct a method for incorporating erosional variability into a system of model evaluation whereby model predictions are compared to measured erosion plot data. The result is a quantitative, statistically based
Estimation of net productivity in China using remote sensing data
In this paper a net primary productivity (NPP) model based on remote sensing data and climate data is developed. And then using this model and 1km resolution monthly AVHRR NDVI data, the spatial distribution and seasonal change of NPP in China
The visualization of turbulence data using a wavelet-based method
This technical communication presents some MATLAB routines for visualizing the structure in turbulent signals based on a standard conditional averaging and thresholding approach. The latter information is derived from a wavelet decomposition
of the signal and may assist in providing a process-based explanation of observed flow features.
Rapid labour data collection for secondary crops: cocoyam and soybean farming systems in Nigeria
A comparative method for the collection of databased on a combination of literature study and field survey is described, and would be relevant for the research worker studying West African land use. (EMS).
