Abstract

River deltas are actively propagating systems as redundant fluvial sediment accumulated hereon after part of the amount being taken away by marine currents. Anthropogenic activities in drainage basins strongly modified such propagation processes by increasing sediment productions over the past millennia and decreasing sediment loads in the past century. The most significant feature is the delta erosion or flooding as a result of sediment trapping in upstream reservoirs in combination with relative sea-level rise. In addition, human interventions within deltaic regions may complicate the morphological patterns with strong spatial variations. Understanding the controlling factors and future trends of delta erosion is of high importance for sustainable development and comprehensive protection of these dense-populated areas.
