[en] Pegase, a model dedicated to surface water quality assessment that helps stakeholders implementing the WFD. That presentation showed 2 different applications directly made by the stakeholders in charge of the water management at the basin scale. The end-users analysed results of the Pegase model in the scope of implementation of the WFD. Differents scenarios were build in order to simulate the way to reach the good status for water bodies. Associated costs were estimated and relevant decisions were oriented using the results of the numerical Pegase tool.
