Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

The study on climatology comprises the compilation and processing of historic data on the Río de la Plata and its adjacent region. It involved a total of 7,757 oceanographic stations performed between 1911 and 2003. The data were grouped in a warm period (November- March) and a cold one (June-September). The variability in the continental discharge of the Río de la Plata made it necessary to group data as a function of three flow levels: high, mean and low. Previous studies reveal a marked change in the average flow regime of the river basin that stars at the beginning of the 70’s with a cycle of humid characteristics during which 86% of the oceanographic stations were collected. Consequently, the hydrological series used to determine the discharge levels corresponds to the 1972-2001 period. The mean flow was 24,045 m3 s-1 and the high and low discharge values were determined at 28,000 m3 s-1 and 17,370 m3 s-1, respectively. The data were analyzed in ten horizontal levels between the surface and 500 m; the levels were defined at: 0 m, 10 m, 20 m, 30 m, 50 m, 75 m, 100 m, 150 m, 250 m and 500 m. Temperature and salinity horizontal distribution for every level, every warm and cold period and every flow condition was mapped. Over a 0.5º latitude by 0.5º longitude grid, mean value, standard deviation and number of observations were also calculated.
