| Abstract: | Distributed hydrologic models are an integral component of spatial decision support systems for watershed management. At these basin (and larger) scales, a common problem in hydrology and other environmental sciences arises from the need to cope with the increasingly sophisticated models and software tools that are used in the management, processing, and analysis of large volumes of data collected from advanced in situ and remote monitoring instruments. The diversity of these tools, and the need for experts and non-experts alike to be able to easily use them, suggests a non-trivial integration problem of building customized systems from disparate (and in many cases proprietary) components. In this paper we address the systems integration problem within the context of a study of surface-subsurface-atmosphere interactions involving soil moisture remote sensing and hydrologic simulation. The simple early steps that were taken highlight the role of the different components and tools in the integration effort. An alternative approach is presented for creating an integrated system, based on a data flow model with the modular components linked within a flexible framework. An example is developed based on established systems integration techniques from the field of computer aided design. |
