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

Peak above-ground biomass of six annually mown salt-marsh angiosperm communities was measured over a 13-year period. Top soil salinity and soil moisture content in the six communities were measured during two dry years. Over the 13-year period the communities showed a synchronous pattern in peak biomass. Year-to-year variation in this biomass could be explained by the rainfall deficit during the growing season, while inundation frequency did not contribute to the regression model. Soil salinity and soil moisture content were significantly correlated with the rainfall deficit over a 2-year study period. Climatically induced year-to-year variation in soil conditions was held responsible for the observed year-to-year variation in peak above-ground biomass.
