Context / Background

Hydrodynamic modelling is an essential method to study scenarios for hydro-environmental problems, such as pollutant or cooling water discharges, sediment transport, lake eutrophication, river training, etc. Delft3D is a world leading 3D modeling suite to investigate hydrodynamics, sediment transport and morphology and water quality for fluvial, estuarine and coastal environments. Since 2011, the Delft3D flow (FLOW), morphology (MOR) and waves (WAVE) modules are available in open source. The hydrodynamic module Delft3D-FLOW is a multidimensional hydrodynamic simulation program that calculates non-steady flow and transport phenomena resulting from tidal and meteorological forcing. The primary purpose of the computational model Delft3D-FLOW is to solve various one-, two- and three-dimensional, time-dependent, non-linear partial differential equations related to hydrostatic free-surface flow problems on a structured orthogonal grid. The equations are formulated in orthogonal curvilinear co-ordinates on a plane or in spherical coordinates on the globe. The hydrodynamic module is based on the shallow water equations. The equations are solved with a robust and highly accurate solution procedure.

Some supported features are:
• Propagation of long waves (barotropic flow);
• Density gradients due to a non-uniform temperature and salinity concentration distribution (density driven flows);
• Transport of dissolved material and pollutants;
• Transport of sediments, including erosion, sedimentation and bed load transport;
• Many options for boundary conditions, such as water level, velocity and discharge boundaries
• Simulation of drying and flooding of inter-tidal flats;
• Turbulence modelling to account for the vertical turbulent viscosity and diffusivity;
• Online visualization of model parameters enabling the production of animations.

Obs.: The course mainly uses the structured grid version, however examples are provided also for the flexible mesh version.
