This book is an introductory textbook in probability and statistical inference. No prior knowledge of either probability or statistics is required, although prior exposure to an elementary precalculus course would prove beneficial in the sense that the student would not see the basic concepts discussed here for the first time. The material discussed in this book is enough for a one-year course in introductory probability and statistical inference. It consists of a total of 15 chapters.

The weak cohesion of the sediment materials often causes localized surface slumping phenomena with significant amplitudes, extending up to several meters, disrupting the equilibrium trend of sedimentation and leading to an accumulation of sediment towards the dam intake culvert. These observations provide insights into the dynamics of the reservoir surface sediment environment, while also demonstrating that current reservoir operation and exploitation conditions can ensure the longevity and safety as per the design of the Cua Dat Hydroelectric project.
