The knowledge on the hydrodynamic property and mass transfer of bubbles is important since it will give guidelines for selecting the operation condition and for reactor design in such processes. For this purpose, this PhD manuscript has implemented an experimental investigation of single air bubbles rising in various polymer solutions (Breox, Polya...
Le chapitre commence par une description des phénomènes physiques propres aux inondations, en particulier, ceux qui les distinguent des écoulements ordinaires en rivière. Ces différents phénomènes sont rattachés aux différents types d'inondations qui ont été énumérés auparavant. Pour modéliser ces phénomènes en vue de la gestion des inondations, il...
One of the most important current issues in the management of lakes and reservoirs is the prediction of global climate change effects to determine appropriate mitigation and adaptation actions. In this paper we analyse whether management actions can limit the effects of climate change on water temperatures in a reservoir. For this, we used the mode...
Averaging the results of different models and/or model realizations has been suggested as a way to improve the estimations of environmental models, especially in meteorology and climate sciences. We applied ensemble modelling to study the hydrodynamic and thermal behaviour of the Mediterranean reservoir of Bimont (France). We used a single-model en...
Ce guide de caractérisation des échanges nappe/rivière vise à mettre à la disposition des acteurs de l'eau des connaissances et des méthodes développées et mises en oeuvre préalablement dans le cadre de travaux de recherche. L'élaboration de ce guide technique fait suite au projet scientifique soutenu par l'Onema appelé Naprom (nappesrivières : obs...

Swales are stormwater source control infrastructures that manage runoff in two dimensions. Generally, a first part of the volume discharged in a swale is conveyed as surface flow and the other is infiltrated underground. A swale traditionally aims at reducing and slowing runoff flows but swales can also decrease the load of sediment and other pollu...

The large floodplains associated with the Amazon River and its main tributaries affect water transport, influence sediment and chemical budgets and support highly diverse ecosystems and productive fi sheries. Approximately 25% of the Amazon River discharge is routed through these systems along a 2,000 km reach between Sao Paulo de Olivença and Obid...
