IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

1. INTRODUCTION
Many deltas in the world cope with drowning and loss of delta land by sediment starvation and accelerated soil subsidence, because of embankment of channels and drainage of land. The urgency of the problem is enhanced by sea level rise (Syvitski et al., 2009). Loss of delta land is a problem, since most deltas are densely populated and seen as valuable because of their ideal location for harbours, agriculture, aquaculture, or tourism (Kirwan and Megonial, 2013). Moreover, deltas encompass vast wetland areas of great ecological value. Delta restoration by re-introduction of natural processes and sedimentation is considered as a mitigation measure, but it is difficult to implement, since natural processes are often in conflict with current activities in the delta. Furthermore, several deltas are subject to sediment starvation, because of a decrease in sediment delivery from upstream. For these delta¡¯s it is uncertain whether delta restoration will be effective
