Popis: International audience; Currently, the distribution areas of aquatic species are studied by using air temperature as a proxy of water temperature, which is not available at a regional scale. To simulate water temperature at a regional scale, a physically based model using the equilibrium temperature concept and including upstream-downstream propagation of the thermal signal is proposed. This model, called Temperature-NETwork (T-NET), is based on a hydrographical network topology and was tested at the Loire basin scale (105 km2). The T-NET model obtained a mean root mean square error of 1.6 °C at a daily time step on the basis of 128 water temperature stations (2008–2012). The model obtained excellent performance at stations located on small and medium rivers (distance from headwater
