In order to understand the subject in its entirety, we must be able to understand the context of our study. A scientific context that define: where is our work positioned, what are the peer researches on this subject, what are the different methods used to conduct these researches?

To overcome this analysis time, it would be possible to perform direct measurements. That is, detecting the presence of BIF through one or more proxy variables.

Today, in order to quantify the fecal indicator bacteria (these are the organisms observed in priority, if there are too many of them, the bathing area is closed), the Paris City Administration carries out water samples that take more than 24 hours to analyze.

To know with precision the quantity of rain fallen on a certain surface we use radar data !

Context of the study: in this part we are interested in the history of urban bathing in Paris, in the new initiatives to reintegrate bathing areas into the urban fabric and in the location of our study site: the bassin de la Villette.

These different data allow us both to feed the model (these are the forcing data) and to compare our simulations with reality!

TELEMAC is a finite element computer program.

It is even possible to dispense with field measurement facilities thanks to indirect measurement methods. With the help of meteorological and other data and hydraulic or statistical models, it is possible to model these FIBs and their proliferation.

Presumably, the contaminations occur after the episodes of rain above the Ourcq canal which flows upstream of the La Villette canal (that we know thanks to the review of

But also the practical context of our study: what are the fields of application of our research? In our case, my work is related to the urban policy of the Ile-de-France region. It is then necessary to integrate many actors, directives or regulations to our project.

With these models, it would then be possible to use the weather forecasts to anticipate the periods of contaminations!

The laboratory has installed two measurement stations on the La Villette basin. They transmit numerous data such as water temperature or conductivity. In a punctual way of other type of measurement are also carried out (speed of current, bacteriological statements).

Review article

In parallel to my report, the collection of bibliographical references is also used to write a scientific review article.

I am working on hydraulic simulations that could help anticipate contamination episodes in bathing areas along the La Villette basin in Paris.

Here are the main steps of my internship.
