Process-model-based Situation Assessment in a Case-study in Limnology
نویسندگان
چکیده
The paper describes work in progress the application of process-oriented modeling to situation assessment within a research project in limnology. In the field study, some 50 lakes in Southern Germany are monitored in order to explore and document the changes in the distribution of a particular aquatic plant, Najas marina, and understand their preconditions. The ultimate objective is using this native plant, which is dependent on favorable temperature conditions, as an indicator for predicting the possibility of the intrusion of thermophilic neophytes. We discuss how process-oriented modeling is used to perform situation assessment, i.e. in this case to explain the (non-)occurrence of Najas marina in a lake, and also discuss challenges to process-oriented modeling, especially concerning spatial and temporal representations and reasoning.
