6.1 Introduction
Based on the objectives of the dissertation, the results of interpolation methods
will first be discussed. The main aim here is to find interpolation methods which
give the best results based on statistical methods such as the root mean square
(RMSE) and watershed and stream network delineation. Then, two integrated
hydrodynamic models (SOBEK and HEC-RAS) will be applied to investigate
changes in the flood hazard and to compare different flow characteristics over time
in the Barcelonnette basin, with the aims of: first, to model different hydrodynamic
scenarios for civil protection purposes; second, to simulate probability distribution
and the return period analysis and third, to determine and compare different
hydraulic characteristics (i.e., propagation rate, flow depth, and inundation time).
In the subsequent section, the results of statistical methods will be presented in
order to detect trend and to find probable abrupt points in spatial distribution of the
observed time series (climatological and hydrological parameters). Additionally,
to detect land use changes from the past until the present and to ensure any affects
on the flow regime of the Ubaye River, the results of the GIS-based process
analysis will be shown. The majority of flood events depicted in this research are
associated with the latter cause of flooding. Therefore, the last and main objective
is to ensure a scientific relationship between climatic and hydrologic parameters,
land use and flood events over time. In this regard, the integration and estimation
of all achieved results seem to be necessary.
