The Precipitation Concentration in the Cheliff Watershed, Algeria: A Critical Analysis for Sustainable Water Resource Management
In this study, a statistical analysis of historical and projected values of the annual, seasonal, and supra-seasonal precipitation concentration index (PCI) was conducted for different stations in the Cheliff watershed. Statistical methods such as breakpoint and trend analysis using Pettitt and Mann...

According to the Pettitt and Mann–Kendall tests, there was an insignificant change in precipitation distribution during the study period.

For the climate projection scenarios, projected PCI values align with historical PCI values.
