EPSRC supported research into afflux at river structures
Afflux is an increase in water level that can occur upstream of a structure at high flows. More formally, afflux can be defined as the maximum difference in water level, for a specific flow, if the structure were to be removed. It is caused by energy losses at high flows through bridges and culverts, and it is made worse by blockage. Afflux can be physically significant in terms of flood levels and leads to a potential for increased losses due to blockage. It therefore needs to be represented in river modelling tools and understood by river engineers and other professionals.

International Association for Danube Research
(IAD) was founded in 1956 with the goal of promoting and coordinating activities in the fields of limnology, water management, and water protection in the Danube River basin. With a length of over 2,800 km, the Danube is -after the Volga- the second longest river in Europe.
