Debris-flows not only cause a great loss of property, but also kill and injure people every rainy season in the mountainous regions of China. In order to reduce hazard and risk, several methods of assessing rainfall thresholds have been provided at present, based on statistical models. However, the limited rainfall data with debris-flow occurrence or non-occurrence makes threshold analyses very difficult.

A year after a devastating earthquake triggered killer avalanches and rock falls in Nepal, scientists are wiring up mountainsides to forecast hazards.

Moroccan Pre-Saharan zone is an oasis system, which it is characterised by extreme events, like drought and flood. The flood risks will likely increases in frequency and magnitude due to global and regional climate change. Flood tends to have an important impact on isolated and poor regions such as oasis regions. This paper aims the analysis of applicability of Flood Vulnerability Index (FVI) in pre-Saharan region of Morocco. The FVI, it is a numerical index that reflects the status of a region’s flood vulnerability.
