Day 3 : Wednesday 15 February

At the start of the afternoon, we still worked on our respective work:

  •          Calibrating of hydrological model : Mike SHE
  •        Calibrating of hydraulic model 1D :  Mike 11
  •         Calibrating of hydraulic model 2D : Mike 21

 

The second step is to reorganize our ideas, concerning uncertainties. We obtain the following list:

HUMAN

DATA (Collection + Input)

MODELS Sensivity (Coupling / Models)

OTHER UNCERTAINTIES

  •          Collecting data (instruments)
  •         Reading data
  •         Inputting data
  •         Model's manipulation
  •         Localization choice
  •          Model choice (related to the model)
  •          Rainfall
  •          DEM
  •          Discharge
  •          Resistance (Land use : manning or strickler number)
  •          ETP
  •        Infiltration
  •         Snow melting volume
  •         Groundwater

 

 

  •          Hydrology -> DISCHARGE
  •        Hydraulics -> RIVER (Input + Physical parameters)
  •          Flood Map production (input + physical parameters)
  •          Case study
  •         Accumulation of uncertainties
  •          Nature of uncertainties
  •          Objective : historical simulation or forcasting (Future uncertainties)

 

Concerning 2D models, we have also uncertainties related to method following:

  •          Quasi 2D (link between two 1D models)
  •          Coupled 1D/2D models
  •          2D models

 

We choose to modify one parameter of different models, to see the sensibility.

  •          For Mike SHE : DEM
  •         For Mike 11 : Boundaries conditions
  •          For Mike 21 : Manning’s number
