Since 1981, the IWA/IAHR Joint Committee on Urban Drainage (JCUD) has organized the triennial International Conferences on Urban Drainage (ICUDs). Recognized as the most important international events in the field of urban drainage, the ICUDs are held in different parts of the world by groups of active researchers selected and designated by the JC after a competitive assessment of submitted proposals. The ICUD conference aims to present latest advances and innovative approaches in fundamental and applied research on urban drainage, taking into account meteorological, hydrological, hydraulic, water quality and socio-economic aspects worldwide. Among its specific interests are urban water quality, sewer sediments, source control, stormwater management, combined sewer overflows, real time control of urban drainage systems, drainage in cold and alpine climates, and data and models related to urban water. The ICUD strives to maintain its long-standing broad international recognition as a prominent platform for the advancement of the scientific knowledge in the field of urban drainage. It considers its activities in the wider context of urban water systems, with the ambition of developing and promoting a sustainable and integrated urban water management.
