Time series analysis and modelling represent a large study field implying the approach from
the perspective of the time and frequency with applications in different domains. Modelling
hydro-meteorological time series is difficult due to the characteristics of these series as
long range dependence spatial dependence the correlation with other series. Continuous
spatial data plays an important role in planning risk assessment and decision making in
environmental management.In this context in this book we present various statistical tests and
modelling techniques used for time series analysis as well as applications to
hydro-meteorological series from Dobrogea a region situated in the south-eastern part of
Romania less studied till now. Part of the results are accompanied by their R code.
