Welcome to the Global Tide and Surge Model homepage!

The Global Tide and Surge Model (GTSM) is a depth-averaged hydrodynamic model, developed by Deltares, with global coverage. GTSM is based on Delft3D Flexible Mesh software and has a spatially varying resolution which increases towards the coast. GTSM can be used to simulate water levels and currents, that arise from tides and storm surges. There is a broad range of applications and (research) projects which make use of GTSM. On this page, we provide an overview of the main developments and applications. We also include a list of publications that make use of GTSM.
