Quality Assurance in Model Based Water Management

During the last decade a growing interest could be noticed in problems related to model based decision support in general (Scholten & Udink ten Cate, 1996) and also specifically in water management. These problems are manifold and include, but are not restricted to technical problems associated with modelling and simulation software, data handling, measuring errors and other uncertainty in system observations, selection of an appropriate model, lack of data, error propagation in coupled models, the increased technological power to calibrate complex models, soft, procedural items associated with stakeholder participation, and translating model results to the level of understanding of managers and decision makers.
