About the project
Riverine floodplains are important for hydrodynamics, ecology, and socio-economics. The variety of functions can be organized within the framework of ecosystem services, which is a trending policy instrument. Some of the fluvial ecosystem services can be computed based on landscape ecological units, such as ecotopes. Ecosystem services vary with spatial and temporal scale, and should be accompanied with a matching ecotope map. However, at the moment there is no comprehensive multi-spatial scale and multi-temporal scale ecotope classification that can be tied closely to ecosystem services. No multi-scale monitoring methods exist that can automate the ecotope mapping. Further need for monitoring arises from the flood reduction measures that are currently implemented and which lead to a high spatio-temporal variability of floodplain ecotope distribution.
The focus of this research is on ecotope mapping using remote sensing methods on different spatial scales. Remote sensing data of different platforms will be used, ranging from mobile terrestrial, via airborne to spaceborne platforms. Temporal aspects of vegetation development will be included in the classification, in order account for the temporal variation of ecotopes. In addition, remotely sensed thematic information, like topography, hydrodynamics and river morphodynamics will be used to refine the classification. Read two-pages overview >>
