The International Conferences on Hydroscience and Engineering ICHE have been a good place for information management, e.g. integrated environmental modelling, in the past. The 10th conference ICHE2012 themed The Water Cycle Under a Changing Climate: Using Hydroscience and Engineering for a Sustainable Future takes place in Orlando in November.
On the IHCE2012 website you find the conference topics. Rainer Lehfeldt chairs a Special Session on Information Management, i.e. metadata, thesaurus, gazetteer, web services, data exchange, web portal, etc. He would very much appreciate if experts in one of these fields participate.
A deadline for abstracts with up to 500 words is March 1 or mail directly to rainer.lehfeldt [at] baw.de.
Please spread the word to others who might also be interested.
