SummaryThe main goal of this proposal is the production of value added information from TerraSAR-X archive data for applications related to water resource management in semi-arid regions. This proposal is framed in a wide set of activities devoted to provide innovative tools for making proper management decisions concerning the use of water in semi-arid regions.
In this context, two pilot projects have been already developed in Burkina Faso and India (see references [1] and [2] in the “Detailed Description” Section). The two case studies are located in the northern basins of the Volta Basin in Burkina Faso, and in Rajastan, in the northwest of India. The chosen regions share similar climates, characterized by the separation between the rainy (3 months) and the dry (9 months) seasons. Such a climate poses great challenges in the water management. The human response to this climate changes as a function of the social, economic and technical background of the people and their environment. Value added of the project will be the comparison of the solutions for the considered countries.
In semi-arid regions, remotely sensed data are crucial for monitoring and forecasting the spatial and temporal dynamic of the physical phenomena at different scales. High resolution images give a relevant value-added support to the decisional processes if appropriate simulation and interpretation models are provided and they can be understood by the population making local decisions. The already developed projects showed the great potentiality of 3m Stripmap data. The TerraSAR-X archive data will be used with two main goals:

1. The extraction of physical information from TerraSAR-X data and the integration between Cosmo-Skymed and TerraSAR- X data.
2. The scaling of the developed activities to wider test areas and different socio-economic contexts, by using the TerraSAR-X Spotlight and Scansar data available in the archive.

Innovative models for surface and Synthetic Aperture Radar (SAR) description as well as for image interpretation will be implemented to this purpose. The proponent team is formed by hydrological engineers devoted to the water phenomena modelling and the definition of the relevant physical parameters to be retrieved and by remote sensing engineers devoted to the development of the algorithms for both direct and inverse problem solutions. Value added products will be provided as a result of the activities organized as follows:

1. Hydrologic model development
Water dynamic models and soil erosion models will be defined along with the principal physical parameters to be retrieved according to the project objectives, both in India and Burkina Faso.
2.SAR processing and image interpretation
A direct chain will be implemented for the modelling of the main physical phenomena and for the simulation of TerraSAR-X data. A complete SAR inverse chain will be developed and implemented on in order to extract physical information from TerraSAR-X data.

3.Products and data integration
Ad-hoc data fusion procedures will be implemented to integrate TerraSAR-X data with multispectral data coming from sensors of the Disaster Monitoring Constellation (DMC), namely UK-DMC 2 and Deimos-1. With these procedures, relevant information coming from TerraSAR-X data will be integrated with maps of water quality, soil and vegetation stress deriving from multispectral data processing.

4.Value added maps production
Value added products will be available as a support for the decision processes in water applications, with particular emphasis on water harvesting. Comparison of techniques, background and results will be provided in technical reports and disseminated in conferences and with publications.
