TELEMAC summer school

Module 1 - Meshing in TELEMAC (1 day) 
The day begins with an introductory presentation, followed by a practical focus on creating unstructured meshes. These meshes are well suited to complex geometries and large‑scale applications, particularly where local refinement is required in intricate or high‑gradient areas. The software used will be Blue Kenue, a freely available tool for pre‑ and post‑processing TELEMAC files. This hands‑on session will demonstrate the key functionality and workflows within Blue Kenue.

Module 2 - Introduction to TELEMAC 2D and 3D (1 day)
This day the focus will be on setting up simulations in TELEMAC‑2D and 3D, modifying input files and interpreting simulation results. It will also cover available parameters and schemes of the TELEMAC software for simulating processes as turbulence and friction.

TELEMAC‑2D is a two dimensional in the horizontal (2DH) shallow water flow model. TELEMAC‑3D is a three-dimensional (3D) model that uses the same horizontally unstructured mesh as TELEMAC‑2D. Applications of TELEMAC‑2D and 3D include:

• Simulations of well mixed flows in the 2DH domain.
• Simulation of flows in vertically stratified water bodies such as estuaries and reservoirs.
• Evaluation of impacts of schemes for tidal power generation.

Module 3 - Introduction to GAIA  (1 day)
This day of the course will focus on morphodynamic modelling, including an overview of the fundamental sediment transport processes implemented in GAIA. GAIA is the sediment transport module of the TELEMAC system and solves the equations governing bed load, suspended load, and bed evolution for a range of sediment types, including uniform sands, sand mixtures, and sand–mud mixtures. GAIA can be coupled with both TELEMAC‑2D and TELEMAC‑3D, and it can also incorporate wave forcing from the TOMAWAC wave model.

Module 4 - Introduction to TOMAWAC and ARTEMIS  (1 day)
This day will focus on modelling waves processes. TOMAWAC represents the generation of waves due to winds or offshore climates and propagation into shallow water. It includes the processes of refraction due to the seabed and ambient currents, wave growth due to the wind, energy dissipation due to bottom friction and white capping, wave breaking and wave blocking. Breaking wave stresses are computed in the TOMAWAC model and these can be used within TELEMAC‑2D or 3D to represent wave-driven longshore currents. ARTEMIS is a model for harbour disturbance assessment that solves the mild slope equation in elliptic form. It includes the processes of wave refraction by bed shoaling, partial reflection and diffraction due to structures.

Environmental consultants, researchers and students who are working on riverine, coastal and maritime hydrodynamic modelling projects and are wishing to learn about numerical modelling and the open source TELEMAC software suite.

At the end of the course participants will understand:

• the components of the TELEMAC suite; 
• applications of TELEMAC; 
• pre and post processing; 
• how to set up and run a TELEMAC-2D model; 
• how to set up and run a TELEMAC-3D model; 
• how to set up a model and perform wave modelling with ARTEMIS and TOMAWAC; 
• the process of modelling with SISYPHE and the different parameters.
