The use of radar for rainfall and runoff estimation is beneficial because of the high spatial
and temporal resolution and large areal coverage; the main objective of this research is the
calibration of the weather radar of Annaba for hydrological applications. To improve rainfall
distribution estimation for the maritime watershed (1,129 km2)(Seybouse, Annaba), located
in the north eastern of Algeria, a new technique was used based on the creation of six virtual
rainfall stations uniformly throughout the area. The rainfall data for these virtual stations are …
