Application of soil acidification models with different degrees of process description (SMART, RESAM and NUCSAM) on an intensively monitored spruce site

    Abstract

    A one-layer (SMART) and a multi-layer (RESAM) soil acidification model with temporal resolutions of one year and a multi-layer model with a resolution of one day (NUCSAM) were applied to an intensively monitored spruce site in Solling, Germany. The major aim was to study the influence of model simplifications and reduction of temporal and vertical resolutions on the simulation of soil solution concentrations. Results showed that all the models were able to simulate most of the concentrations reasonably during the examined period (1973-1989). However, the one-layer model, SMART, had difficulties in simulating strong changes in soil solution concentrations owing to a lower retardation in the soil system.
