The SedDis tool is a decision-support tool for selecting the optimal segmentation for the sediment in TOXSWA simulations. The TOXSWA model is used to calculate exposure concentrations of pesticides and their metabolites in watercourses and ponds. For the parameterization of the water body, its water layer and sediment layer need to be spatially discretized. For the sediment layer, the size of the grid (segmentation) is crucial. Selecting the optimal segmentation ensures that simulated concentrations are calculated with a satisfying accuracy when simulating the transport of strongly sorbing compounds within the TOXSWA model. The theoretical background and methodologyfor the SedDis tool is described. The procedure for using the SedDis tool is provided. Instructions for running the tool with an example (selecting standard or fine segmentation for a given scenario) are given.
