On behalf of the International Working Group on Data and Models of the IWA and IAHR Joint Committee on Urban Drainage, it is a great privilege to host the 11th International Conference on Urban Drainage Modelling (UDM) in Palermo next September 2018. The UDM Conference deals with problems/modelling of quantity (water) and quality (pollution) related to urban areas such as: rainfalls, flooding, sewer processes, wastewater/stormwater treatment, receiving water body and integration of them, socio-economic interactions and modelling tools, etc…).

The conference has been running since 1986 and in 2018 will be held the 11th edition, a monumental achievement of the urban drainage community. The UDM conference series started back in 1986 in Dubrovnik, former Yugoslavia. The second edition of UDM was organized in 1991 also in Dubrovnik. After the first two editions in Dubrovnik, the conference has travelled across the globe to the River Volga (1994), London (1998), Orlando (2001), Dresden (2004), Melbourne (2006), Tokyo (2009), Belgrade (2012) and Québec (2015). In 2018 we will be meeting in Europe once again. 

The UDM seeks to create a forum for promoting the discussion amongst scientists, professionals and academia on urban drainage thus providing to women and men of this field decisive ideas. We also hope that your participation to the Conference in Palermo will provide you the opportunity to explore the rest of Italy, to savor its diverse and rich mixture of ethnic traditions, culture, cuisine and religious sites. We look forward to welcoming you to the colorful and vibrant city of Palermo and see you in 2018.
