March 2021 - Tunisia: Modeling Training

March 2021 - Tunisia: Modeling Training

21 January 2022 admin

During the last week of March 2021, CONCEPT provided senior engineers withNational Sanitation Office and from theCompany of Promotion of the Lake of Tunis (SPLT) training on the modeling of watercourses using the HEC-RAS software, applied to the North Lake Belt canal in Tunis.
ONAS and SPLT have been jointly managing this 5 km long canal since the 1980s, which has a dual function: on the one hand, to protect the lower town of Tunis against flooding in wet weather and, on the other hand, to avoid the frequent pollution of the North Lake by the effluents of the combined sewerage system of this part of the city.
The objectives of the training were to:

  • Master the theoretical bases of free surface hydraulics (knowledge of the methods of calculation of the water line, of flows in the right of structures)
  • Know the prerequisites for the implementation of river hydraulic modeling (data and basic tools needed)
  • Know how to model the flow of a 1D river in steady state and in transient state and exploit the results
  • To understand the model of the Tunis North Lake Beltway which integrates lateral weirs and pumping stations.
    This training concludes the study of improvement of the functioning of this canal system, study entrusted to CONCEPT by the two organizations mentioned above.
