Abstract
Deltas worldwide are at risk of elevation loss and drowning due to relative sea-level rise. Management strategies to restore or enhance sedimentation on delta plains, Sedimentation-Enhancing Strategies (hereafter SES), are now being pursued in many deltas but there has been limited cross-disciplinary and cross-delta review. Here we compare 21 existing ... read more

Note: Funding Information: Agencies involved in planning and implementation of SES vary ( Table 1 ). Sometimes it is a top-down decision where a national government decides to target delta sedimentation and employ research institutes or private consultancies to design and test solutions (e.g., Canal del Dique, CDD ( Sokolewicz et al., 2016 )). In other cases (e.g., Beel Bhaina, GBB) residents implemented an SES, which was then later acknowledged and extended by the national government. In the Danube and Wulan deltas (GBP, GBP, WPS), NGOs coordinated and funded the SES with the support of local research institutes. Kooragang Island (HKI) and the Jiuduansha wetlands (YJW) projects are exceptions, as they were organised and developed by a local university (in collaboration with local authorities). Often projects are also supplemented with EU (Rhine-Meuse: RNW, RZK) or World Bank funding (Danube: DBP, DCP) and in some cases (Kooragang Island: HKI) funding from private organisations.
