| Zusammenfassung |
| The integration of hydrological models and Geographical Information Systems
(GIS) usually takes two approaches: loose coupling and tight coupling. This
paper presents a tight coupling approach within a GIS environment that is
achieved by integrating the urban flood model with the macro language of
GIS. Such an approach affords an uncomplicated way to capitalize on the GIS
visualization and spatial analysis functions, thereby significantly
supporting the dynamic simulation process of hydrological modeling. The
tight coupling approach is illustrated by UFMArcGIS (Urban Flood Model with
ArcGIS), which is a realization of an urban flood model integrated with the
VBA (visual basic of application) language of ArcGIS. Within this model,
major stages of model structures are created from the initial parameter
input and transformation of datasets, intermediate maps are then visualized,
and the results are finally presented in various graphical formats in their
geographic context. This approach provides a convenient and single
environment in which users can visually interact with the model, e.g. by
adjusting parameters while simultaneously observing the corresponding
results. This significantly facilitates users in the exploratory data
analysis and decision-making stages in terms of the model applications. |
