1.6. Second week

During the second week of HydroEurope 2017, we have received this topic:

"Resilience estimation for 94 event (Nice area, left bank) and uncertainty analysis"

For this second topic, this is our presentation, that we will show on Feb, 23rd. 

Presentation of 2nd week

    To answer to this topic, we decided to follow these contents: 
    To start the study of resilience estimation, we need a flood map which represents an event. For our case, we use a flood map of the 1994 event for Nice area.
On the pictures, you can see the location of our flood map, provided by our tutor:

Concept of Resilience 

    Now, we speak about the concept of resilience, it's necessary to define a few notions: 

Resilience: the ability of a system, to cope with change and capacity to recover a normal state.

Tool to measure resilience: 
We use the FRI (Flood Resilience Index). It's a tool to help decision maker, which enables the evaluation of flood impact to reduce the flood damage.
If FRI is small -> resilience is small -> and we need to improve the flood responses. 

To estimate the resilience: differents steps
Flood modelling -> Flood map -> Resilience estimation (field study).

Estimation of Resilience: FRI tool with building and city scale

 To build the Building and city scale, we used the following formula & criteria:

        For Building scale: 

 We analysed 8 urban functions: Health, Leisure and Tourism, Food, Safety and Administration, Working, Education, Housing, Religion and Cemetery. For different critical requirement: 

    For City scale: 

    We analysed for 5 dimensions: Social, Physical, Natural, Institutional, and Economic. And for 91 indicators, like an example: 

Uncertainties related to the resilience:

The following questions are asked by the supervisors during the presentation:

1. Oliver Delestre --  Related to uncertainties of the flood depth, did you manage to build a 2D model to show the water depth uncertainties?
-- Our task is to estimate the flood resilience and analyze the uncertainties due to resilience, so we focus on the resilience study, not the model building. In fact, we did 1D, quasi 2D and 2D model of lower Var catchment last week, so this week we start with the flood map.

2. Oliver Delestre -- But the flood map you showed in the presentation came from your Tutor?
-- Yes, we took the flood map from out Tutor because we tried to build the flood map in three different software -- ArcGIS, HecGeoRAS and Iber but we did not get a better results than the one from our tutor.

At the end, what we have to mention, from both our teammates and our supervisors, our topic this week is the resilience study. So if we are asked to build models (like the question last week - comparison of 1D, quasi 2D and 2D model), we definitely will do it with heart and souls. The resilience study follows the process we mentioned in the slides, which is confirmed before we started this week.
