The Dependent Stratification tool is a Matlab® software packet developed in commission of Flanders Hydraulic Research (FHR). The tool is a standalone executable which facilitates and automates the stratification of a main extreme value distribution and the dependent stratification of secondary extreme value distributions in order to generate synthetic quantiles with corresponding frequencies. The tool is part of a suite of software tools to facilitate the probabilistic formulation of hydraulic boundary conditions. This report is a manual for the tool. It assists the user when installing the tool. Furthermore it provides an in depth description of the workflow and the functionalities of the tool.
