   Very intensive rainfall at the beginning of July 1997 caused extensive flooding in the eastern part of the Czech Republic. On Friday, 4 July, a low pressure system, which originated in northern Italy, tracked northeast to the Moravia region of the Czech Republic. This system brought extreme rainfall as it moved to the southeast of Poland and Silesia on the morning of 6 July. Over a 5-day period the total rainfall for one-third of Moravia (10 000 km2) was 500 mm. The average rainfall for the Czech Republic is 600 mm yr. This event caused 100-400-yr discharges in regional streams. On Tuesday, 8 July, the first RADARSAT image was ordered and the satellite imaged the northern part of Moravia on 10 July. An additional four images were ordered to archieve intermediate stages of the flood. Areas of flooding were determined on all images. Delineation of flooded areas in post-flood images was possible owing to high radar sensitivity to the high soil-moisture contents.
   Changes in soil moisture, detectable over thousands of square kilometres, can also serve in studies of soil permeability or hydrogeological conditions, if imaged at successive time intervals
