The influence of dredging activities on the morphological development of the Columbia River mouth

This is a numerical modelling study on the impact of dredging and disposal activities on the long-term morphological development of the Columbia River mouth (MCR). Dredging activities removed 120 Mm3 of sand from the MCR during the studied interval between 1958 and 1999. Only one-third of this volume was disposed in the active littoral zone....

Morphological modelling of the Atrato river delta in Colombia

The Colombian government aims to establish a connection that bridges the Atlantic Ocean and the Pacific Ocean. The new connection will largely take place on the current Atrato River, which has not yet been upgraded for a more extensive use of navigation in the near future. A bottleneck in the river is the delta area. Without structural dredging...
