Ecosystem modeling of sediment dynamics in the constructed wetland carla in central Greece

Abstract

Constructed wetlands are complex dynamic ecosystems. Ecosystem-level modeling of the processes that take place in a constructed wetland is a useful tool for understanding wetland function and structure and for making predictions. We present a primary productivity model for the wetland that is currently under construction in the area of Carla in central Greece, restoring one of the most important wetlands in Europe that was drained in 1962. The model includes the area's hydrology and geomorphology and is used to explore the role of different wetland structures and functions on the dynamics of primary producers and sediments in the constructed ecosystem, in order to provide a better understanding of the processes involved and the nutrient dynamics in these processes. © 2009 WIT Press.
