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...

A critical review of the different hydrodynamic mathematical models available for nonideal flow configurations of both low-rate and high-rate anaerobic reactors is presented, including upflow anaerobic sludge blanket reactors, anaerobic fluidized bed reactors, anaerobic biofilters, wet and dry digesters. The review highlights the role of mathematic...
Dans la vallée du fleuve Sénégal et le delta intérieur du fleuve Niger, la crue annuelle inonde un vaste lit majeur par des chemins d'écoulement complexes. Pour représenter la propagation d'écoulement entre lits mineur et majeur sur ces zones très plates, on utilise un modèle sans données topographiques initialement développé pour les lits mineurs ...
