| There is a lack of knowledge about some rainfall properties which are: representative diameters, drop size distribution, drop velocity distribution, kinetic energy and raindrop arrival rate. This paper presents a study about the characterization of these important properties of the rainfall and their relation with the intensity. The data of rainfall are obtained with a disdrometer. This instrument provides information about raindrop sizes by recording the total number of raindrop impacts, minute after minute, grouped in 20 classes according to their sizes. The model used in the present study was originally developed by Joss and Waldvogel (1967). The disdrometer is installed on the terrace at E.U. Forestry Engineering building of Technical University of Madrid. It is placed where any obstacle could disturb or change the regime of raindrop fall. The sampling surface of the disdrometer recorded rainfalls during two years. The total registered data were more than 3500 minutes of rainfall with different intensities. With the collected data the relationship between drop size distribution-intensity, drop velocity distribution-intensity, the median volume diameter-intensity, the median energy diameter-intensity, kinetic energy distribution-intensity and raindrop arrival rate-intensity are studied for the total number of samples. The results obtained are useful because they can have multidisciplinary applications in hydrology, meteorology as well as soil sciences. | |
