Day 5: Feb 20th, 2017

Today, second week of the Face to Face Meeting

09:00 - 11:30 : Conferences
    • IRSN: Protection of Nuclear Installation against Floodings
    • EDF: TELEMAC Cases of study
14:00 - 15:00 : Review of the presentation done the last week on Friday.

            Many things to learn and remember for the next presentation:
    • Be extremely careful when trying to compare two graphs. 
      • Verify that the axis are the sames, 
      • Do not forget the axis label and units
      • Do a superposition of the curves to be compared
      • Do not show results that are not good
    • Try different models to be sure that at least one will work and do not present a model results if it's going wrong
    • Have a real part in the presentation where the answers to the answers asked are given
15:00 - 17:30 : Teamwork

        We've been asked a new question that is the following:

"Impact & Consequences of numerical methods on hydrological & hydraulic models"

    We have tried to select the key words in this question to be able to develop the team organization and the structure of the                presentation for the days coming.

    Differents groups have been made working on the following things:
  • Introduction: Strategy / Objectives 
  • (Theoretical Background) Hydrological Models: MIKE SHE (Finite differences) & HEC-HMS (?)
  • (Theoretical Background) Hydraulic Models: IBER (Finite volumes) & HEC-RAS 2D (Finite differences)
  • (Results) Hydrological ModelsMIKE SHE (Finite differences) & HEC-HMS (?)
  • (Results) Hydraulic ModelsIBER (Finite volumes) & HEC-RAS 2D (Finite differences)
  • Impact & Consequences for both

Day 4: Feb 16th, 2017

Today at first we discuss the construction of presentation and made a plan of it with division of tasks.
The group working on HEC-HMS, has finished working on the model and the other model has been built and we still doing the calibration until obtaining the final model.

The group working on Mike SHE they have completed the task on the calibration, inputing new rainfall data to thier model. 

The Flood Resilience report has been finished obtaining the results for the macro scale study of the flood event of 1994 in Nice. Considering a economic and social scenario, the overall Flood Resilience Index (FRI) obtained is 3,2 for the chosen scenario. The radar chart below represents the different FRI for each urban dimension.


At the end we discuss the results of our work from the week and make conclusions and we are preparing the presentaion for 17/02/2017  

Day 3: Feb 15th, 2017

The group for MIKE-SHE finished the original model running with 75m resolution data, and started model calibration.  Because of the limited server resources, the calibration has not been completed. But we have started to adjust the rainfall data (with ArcGIS) which are prepared in order to find how it affects the simulation result.

In addition, Anna Krawczyk and Sara Sampé have been working on the Flood Risk Management report for this week. The mapping of the Flood Resilience Index (FRI) has been finished for the parcel scale using ArcGIS which can be seen in the figure below.

For the group working on HEC-HMS the model has been set-up and it running. However the calibration should be performance. In the figure below we can see the progress in the map and the results in the outlet of the model.

Day 2: Feb 14th, 2017

Today, for the MIKE SHE group, the measurement points are inputted in the Arc GIS software. Hence, we can start to change the geometry data for the Var catchment and add the value of spatially distributed. Moreover, we already finished to set up the MIKE SHE modeling. 

The group working on HEC-HMS, has continued working on the model, and finishing the data preparation. The two groups has been working together in the selection of the data. 

Furthermore, two participants of the group are working on the resilience project. 

Day 1: 13th Feb, 2017

In this first memorable meeting, we have discussed the presentation we did that morning. and the supervisor gave some comments about the PPT. Once we got the question (Interest and added value of spatially distributed parameters and variables like rainfall), we divided into two groups and distributed the task. 

Scheme of the work distribution for this day:

After that, all of us became familiar with the models MIKE-SHE and HEC-HMS, which were chosen by our team to study with . Also, we decided the detailed plans for this week.
