Short Presentation of the Project

IllustrationThe course project is a flood analysis study of the Var river catchment, which is located in the South of France nearby the city of Nice. The Var catchment has an area of about 2822 km2 and elevation from 3000 m in the mountains to 0 m at the mouth to the Mediterranean Sea. In November 1994 the Var river had a large flood with a peak discharge of 3500 m3/s.This flood destroyed two weirs, leads to large flooding areas and several damages on the infrastructure (e.g. bridges, roads).You will find several photos from this event in the Var exercise presentation by Prof. Gourbesville in the Project section.

IllustrationThe course project deals with the flood analysis during November 1994 in the Var catchment using modern Hydroinformatics methods and tools.The goal of this case study is the evaluation of removing embankments and to discuss consequences for flood events based on the flood Nov 1994.

The project has several main tasks (work packages):

  • Runoff analysis based on rainfall data and DEM
  • Simulation of Var river for the flood Nov 1994 with Mike11
  • Validation of simulation results by measurement data
  • Discuss recommendations for management of the Var river catchment
  • Discuss alternative solutions for flood prevention in the lower valley of the river
  • Project performance in team work based on Web-based Collaborative Engineering
  • Reporting of all project work as Web documents

The data files for the case study are stored in the Data section.

  • The catchment is described by an digital elevation model (DEM) with a grid size of 300 m and of 75 m. Land use and vegetation for this DEM are given for the 300 m grid. This data are part of the Var data set 1.
  • Var data set 2 contains data from the flood Nov 1994, river data (network, cross sections, weirs, boundary conditions) of the lower valley for Mike11 as well as guides for flow resitance parameter.
  • Rainfall data for the flood period are given in two files with 1 hour and 24 hour time step.
  • Discharge data are given for 1974 - 2001 for each month.

Please read carefully the description of the different data sets, before you start your work!
