The most important impacts of climate change relate to temperature and precipitation. Precipitation is particularly important, because changes in precipitation patterns may lead to floods or droughts in different areas. Also, precipitation is a major factor in agriculture and in recent years interest has increased in learning about precipitation variability for periods of months to annual and s...

Keyword: Pearl River Delta extreme water level sand excavation non-parameters test This paper is concerned with identifying the spatial and temporal patterns in the annual maximum and minimum water level in the Pearl River Delta (PRD) region. The Mann–Kendall test and Pettitt test are used to detect trends and abrupt change points, and the Trend Free Pre-Whitening (TFPW) approach then eliminate...

L’évolution de la pluviométrie dans zone sahélienne a connu d’importante variation depuis les années sécheresse. Cette été considérée par nombreux auteurs comme plus affectée variations climatiques ce siècle. Cependant, à l’intérieur cette même zone, paramètres ont des comportements très variables. Ainsi, étude pour objectif d’analyser variabilité spatio-temporelle au Burkina Faso en tenant com...
