Spatial variability of concentration and aggressiveness of Precipitation in north-east of Algeria

In this study, the spatial variation of daily and monthly concentration precipitation index and its aggressive ness were used in 23 rainfall stations in the extreme north-east of Algeria over the period 1970-2010. The trend was analysed by the Mann-Kendall (MK) test. The results show that daily prec...
