This file includes all simulation start files and developed solvers described within the doctoral thesis of Tabea Broecker. The thesis is entiteled "High-resolution integral modelling approach for flow and transport in groundwater-surface water interaction space" and was submitted to the Technische Universität Berlin in 2020. For all simulations the OpenFoam version 2.4.0 was used. , In the folder "solvers" all solvers, which were not included in OpenFoam 2.4.0 but developed and used for the described test cases, can be found. They have to be installed before running. The codes as well as the installation of a new solver in OpenFoam are described in the thesis in Appendix A. In the folder "testCases" all simulation start files and corresponding evaluations of the described test cases can be found. For a precise description of the test cases and the results I refer to the doctoral thesis. In Appendix B of the doctoral thesis an overview of all test cases including a general description of each case and all applied settings can be found.
