The key
aims of this thesis are to identify the
challenges and strategies for implementing Flood Resilience and Smart
Water
Management (SWM) solutions at both the policy and field level to for
efficient
water management. In the next decade, more than 4 billion people
worldwide will
be living in areas of water scarcity and more than two thirds of the
world’s
population will face water-stressed conditions. This future water
shortage
requires immediate action on development of resources, reduction of
demand and
higher efficiency in treatment and transmission. In addition, future
flood risk
management requires immediate action in risk assessment, defence and
alleviation systems, forecasting and warning systems and institutional
and
governance measures. And with the climate change impacts, extreme
events will
be more frequent and severe. As a result, there is a necessity to adopt
alternative strategies rather than the traditional predict-and-prevent
approach
which mainly focuses on reducing the probability of occurrence of
disturbances;
where this type of approach often led to an extensive construction of
protection dykes, flood defenses and other structural solutions along
river
channels and floodplains, creating a false sense of safety, which
increases the
vulnerability to the consequences of possible floods. The first half of
the
thesis explores the various applications of flood resilience strategies
and the
available solutions that are and can be implemented to mitigate flood
impacts.
It also examines the effectiveness of flood resilience solutions
through
hydrological hydraulic simulations of a real case study in South Korea.
From the analysis,
recommendations and strategies are developed where it is found that
Smart Water
Management is an enabler for the implementation for Flood Resilience
solutions
and has great synergy with Flood Resilience concepts. The second half
of the
thesis explores the concept of Smart Water Management and discusses the
technologies required for the implementation and their challenges and
limitations. Successful case studies of smart water solution
implementations
are investigated and used to validate the direction and action plans
for the
implementation of smart water solutions. In addition, a framework for
the
implementation of Smart Water System for an urban city, which includes
the
water demand system and water supply system, as well as a leakage
detection
indicator for water supply system are proposed. Finally,
it discusses the importance of smart
city connections between
the different domains of a smart city with the smart water system and
how these
connections occur within the smart water system.
