COLLABORATIVE ENVIRONMENTAL MODELING: A ROADMAP FOR INTEGRATED WATER RESOURCES MANAGEMENT

摘要

Collaborative modeling (CM) is motivated by modern environmental problems, complex policies, and solution decisions. CM is empowered by environmental science along with modern computer technology that allows modelers to scrutinize the environmental processes using a holistic approach. Such modeling systems are characterized by a dynamic and interdependent nature and involve social, economic, and environmental contemplations. In this paper, a collaborative system has been developed which evaluates the hydrological, environmental ecosystem and socio-economic dynamics in lakes and wetland watersheds. The developed system consists of the following models for: surface hydrology, groundwater hydrology, lake/reservoir water balance and operation, environmental ecosystem and a socio-economic interactions. These models have been developed to be spatially and temporally synchronized and they are coupled using the OpenMI standard to produce simultaneous simulations. A model calibration service has also been incorporated in the modelling system. Output visualization is presented in elegant and useful tabulated and graphical formats. The system has been applied to the Lake Karla watershed, located in Thessaly region, Greece. However, it is general enough that can be easily applied to other similar case studies. The design of the modelling framework follows the loose integration paradigm allowing the inclusion of other similar, yet heterogeneous models, with seamless modifications. We finally include a version of a web service tool for the intercommunication between the surface hydrology and the lake water balance model via the internet. This modeling and model coupling methodology sets the foundation of an online repository of models which may run and interchange online time series data.
