It is open now the inscription period for abstracts. However due to how close in dates is the International Water Association IWA, we have thought that there is no point in having two international conferences in English separated for just one week. We will inform about this decision in another post.
We really regret the situation created but we don't think it is a good idea to interfere with the IWA, we are not that much people working in the same topics and there is no point in having too many conferences in a year.
