Hypothesis (a):
Interpolation techniques are suitable tools to control the quality of digital
elevation model
Objective (a):
To find which interpolation method gives the best result based on statistical
methods and watershed and stream network delineation
Hypothesis (b):
For any flood hazard assessment, simulation of variability of flood crisis
scenarios and flood frequency analysis is necessary for civil protection purposes
Objective (b):
To apply different DEM resolutions, to investigate how much the accuracy of
the results is influenced by provided input data
To investigate river changes over time and see how river morphology affects the
flow propagation
To simulate variability of dyke scenarios and to estimate the capacity of the
channel and dykes' resistance to the different volume of water. Additionally, to
determine the hydraulic characteristics (i.e., propagation rate, flow depth, and
velocity) for each simulation
To model different hydrodynamic models and to investigate advantages and
disadvantages for any future research in similar characteristic river channel and
flood plain
To analyze probability distribution and return period analysis
Hypothesis (c):
Topographic elements can be used as strategic flood defense systems especially
to delay flood waters in order to evacuate people
Objective (c):
To simulate the variability of flood crisis scenarios for dyke failure
Hypothesis (d):
Climatic variables influence flow distribution
Objective (d):
To find any probable abrupt points and trend analysis in spatial distribution of
observed data sets (climatologic and hydrologic parameters), statistical methods
should be implemented
Hypothesis (e):
Flow propagation in the Ubaye river is affected by anthropogenic activities and
land use change
Objective (e):
To detect land use change from the past until present. GIS process analysis
should be used to ensure any affects on flow regime of the Ubaye river
1.4 Work Plan and Structure of the Thesis
This thesis is structured into eight chapters.
Chapter 1
provides a foundation for the
research and introduces the problem and subsequently, the hypothesis, the aim, and
objectives of the research, the workflow and structure of the thesis.
Chapter 2
gives a
comparative overview of the major challenges faced when dealing with flood
hazards.
Chapter 3
is constituted by the conceptual and methodological approaches
leading the research dealing with digital elevation model (DEM) quality control
modeling, interpolation technique comparisons, and hydrodynamic simulation with
respect to different flood crisis scenarios, frequency analysis, climate change
detection, and land use change estimation from the past to the present.
Chapter 4
describes the study area and the Ubaye River characteristics.
Chapter 5
covers
available data.
Chapter 6
explores the results of SOBEK and HEC-RAS simulations,
climate change detection, and statistical analysis for land use change and attempts to
estimate the feedback and interaction between all achieved results scientifically.
Chapter 7
provides an overall conclusion derived from the results of the applied
