The evolution towards integral and integrated catchment modelling is impeded by a large number of factors, where of the two most important are the incompatibility of the existing models and the computational effort needed to run simulations. Incompatibilities arise because of differences between software suppliers, time and space scales, the level of detail, the intentions of the different models and many more. Calculation times of full hydrodynamic models limit the use of integrated catchment models for flood prediction systems, real-time control, uncertainty analysis and other applications.
The intention of the present study is to develop and apply a methodology for integrated catchment modelling based on the use of conceptual models for each subcomponent. These conceptual models will replace the existing (hydrodynamic) models for simulating river courses, sewer systems, estuaries, rainfall-runoff, groundwater hydrology and water quality components. Conceptual models can be situated somewhere between empirical and physically-based models: they have a limited physical basis but need to be calibrated with measurements or model results.
This report summarizes the results of the first work package of this study. A literature review was set up to identify the possible conceptual model structures that can be used for modelling every subcomponent of the integrated model. The overview contains a description of the derivation, algorithms and application of a large number of conceptual models. One of the key elements here was the possibility of these models to conduct longterm simulations in a very short period.
A generalization of the selected model structures was then carried out to allow an application of one technique to multiple (sub)components of the system. This has led to a proposal of a limited number of conceptual model structures that will be used further on in the study for constructing the integrated catchment model.
