WATERMED

WATer use Efficiency in natural vegetation and agricultural areas by Remote sensing in the MEDiterranean basin.

The WATERMED project runs from year 2000 to 2002. The project is funded from the European Union 5th Framework Programme within the INCOMED programme.


Objectives
The general objective of the WATERMED project is to develop a comprehensive method for the study of the water use and the resistance to the drought of the natural and irrigated vegetation in the Mediterranean Basin, by means of a combined historical and current space-based remote sensing database, vegetation models and field measurements. The general concept is to integrate all available data of the studied environments.

To carry out a climatology of the study area to distinquish the most fragile areas to the drought and the evolution of the ecozones. The study will map the land cover change in the time period chosen. The study will be made by using NOAA AVHRR satellite data, high resolution imagery, airborne remote sensing measurements and field measurements.
A study of water use efficiency in four specific test areas chosen in the following critical zones:
the Guadalentin Basin (SE Spain)
the Ouarzazate province and Marrakech (SE of Morocco)
the lower Rhone valley (SE France)
the northern region of the Sinai Peninsula in Egypt.
The contribution from Risø is focussed on the upscaling of surface heat and water vapour fluxes from point scale to a scale of 1 km * 1 km. This is the resolution the NOAA AVHRR satellite data. The study will be based on high resolution satellite data from selected sites. The surface flux modelling will be done with a new version of the microscale aggregation method. Further will the upscaling results be compared to other methodologies.
