The proposed concept makes use of several highly innovative modelling approaches and building blocks, that flexibly can be combined to build a tool for decision support on integrated water systems, which may consist of catchments and/or rivers, sewer systems, etc (both large and small scale systems). The modelling approaches are flexible and modular, such that we can create tools tailored to the intended applications. Also, the level of model detail is adaptable, thereby obviating the creation of overly complex and too rigid models. Different temporal and spatial scales can be covered.
Due to their flexibility and very short calculation times, the created models are ideally suited for various applications requiring numerous or long term simulations, and integrated analyses, such as simulations of the effect of climate scenarios, land use changes, water management scenarios; real-time applications, including intelligent real-time control and warning systems; evaluation and optimization strategies: from the installation of blue-green solutions, retention and infiltration basins along rivers and sewer systems, to strategies to optimize the water availability at catchment or regional scale, to integrated flood - drought control strategies, hydropower, etc. The tool can account for uncertainties and probabilistic analyses through ensemble runs.
