Modélisation complète du bassin de la Meuse

Partners have finalised the report and summaries of Action 6 - hydraulic modeling. The papers describe the methodology to run a full modeling of the Meuse river from spring to mouth and present results at the basin scale as well as on a selected numb...

Modélisation hydraulique

  • Hydraulic modelling of the river Meuse and main tributaries for potential floods in 2030-2050 and beyond 2050.

Hydraulic modelling is necessary for the identification of future consequences of floods and low-flows.

Models already exist in the countries and regions of the river Meuse. Presently, each hydraulic model is based either on the outputs of rainfall-runoff models or on statistical hydrological data. The hydraulic models along the Meuse do not use the flows or water levels from upstream models.

After listing the characteristics of the different models, the partners will work on ensuring their compatibility. A methodology will be set up for the comparisons, the exchange of outputs, and the hydraulic run itself.

The most upstream hydraulic models of the river Meuse, as well as a limited number of major tributaries, will run the scenarios agreed previously. The outputs will be fed into the downstream model which will run and forward data to a third hydraulic model and so on until the mouth of the river is reached. This will be the FIRST INTERNATIONAL RUN of the MEUSE RIVER.

Special efforts will be developed in the area between Ampsin & Maaseik where hydraulic modelling is of great importance for both sides of the frontier. Current models are too heterogenic and improvement is needed to give coherent outputs.

The largest flood recorded at the Dutch/Walloon border measured around 3000 m³/s (1926 and 1993), but the design discharge is much larger. We need to achieve a better insight in the propagation of (extreme) flood waves in the Walloon/Flemish/Dutch border region. The measures of peak flows on both sides of the border can deviate up to 10%; this problem will thus be solved in parallel.

The Walloon model accounts for a detailed 2D spatial resolution and iterates on time to produce inundated areas corresponding to steady statistical discharges. The Dutch/Flemish models are dynamic with a limited spatial resolution. Each can be improved by learning from the others.

At least 3 meetings are planned during this Action. They can be hosted at the IMC.
