Radar finds water for Sudan refugees

A new technique using satellite radar images may hold the key to providing the water needs of 200,000 Sudanese living in sweltering heat in camps along the Chadian border.

Alain Gachet, a geologist who spent most of his working life exploring for oil and mining companies, has developed a system that uses satellites orbiting 800km above the earth to search for water.

A good deal of geological exploration now uses the visual images produced by Nasa shuttle missions.

But this only sees the surface features of the earth. Dr Gachet uses two forms of radar to look deep below the soil.
