Besides work related to the [[Generation and Modification of Computational Grids|generation and modification of grids]] the preparation of proper boundary conditions is one of the most important but also sometimes tedious steps preparing simulation runs using [[Mathematical Models for Coastal Areas and Estuaries|mathematical models]]. In addition to initial-conditions, time- as well as spatially varying boundary conditions must be prescribed for all boundaries of the modelling domain during the whole simulation period. Data needed may be for example bottom roughness, wind above the water surface (see in this respect also Wind über Ästuaren), water level elevation at the ocean boundary (e.g. North Sea), fresh water flow, etc.
