Effect of dyke construction on water dynamics in the flooding savannahs of Venezuela

摘要

In the flooded savannahs water is the main factor determining the ecosystem and its change. During flooding, the level of water and the duration of flooding are highly dependent on the relative height position of the ecosystem unit. To understand the spatial processes in the ecosvstem one must know the water dynamics in the area. In order to quantify the water content during the year, a digital elevation model (DEM) is needed.
