Floods are an overflow of water that covers normally dry land. Flooding has been a global issue over the past decade, displacing people and destroying assets. Floods impact communities through social, economic, and environmental consequences. Immediate effects include loss of life, property damage, and health issues, while longer term impacts disrupt infrastructure and services. Suggested solutions include better flood warning systems, modifying structures, constructing buildings above flood levels, protecting wetlands, and improving flood defenses. Challenges to implementing solutions include population growth, climate change effects like sea level rise, and deforestation.
2. INTRODUCTION
In the nous of "flowing water", the term
might be suitable to the entry of the tide.
Floods be situated an area of learning of
the self control hydrology and are of
important regarding agriculture, civil
engineering and public health.
WHAT IS FLOOD ??
A flood is an abundant of water
that buried land that is ordinarily
dry.
The Europeon Union (EU) Flood
Directive defines a flood as a
covering by watar of land not
normally covered by water.[1]
[1]."Directive 2007/60/EC Chapter 1 Article2".

3. Flooding has been situated a worldwide
plague for the preceding decade
Flooding tragedy which
displaces the people by
destroying their assets, houses
and other valued properties
and in numerous cases
demanding human lives

4. It was influence on both individual and communities, social,
economic and environmental consequences
The effect of flood,
underlying heavily
on their location,
duration, depth and
speed, as well as the
weakness and value
of the artificial
natural and erected
environments.

➢ the instant effects of flooding
comprise loss of human life,
destruction to property, damage of
plants, lost livestock, and
worsening of health conditions due
to waterborne diseases.
5. EFFECT OF FLOOD TRAGEDY
5
➢ the instant effects of
flooding comprise loss
of human life,
destruction to property,
damage of plants, lost
livestock, and worsening
of health conditions due
to waterborne diseases.
➢ disturbance to provisions
of clean water, wastewater
treatment, electricity,
transportation,
communication, education
and healthiness care
6. EFFECT OF FLOOD TRAGEDY TO ENVIRONMENT
6
➢ Positive impact such as an
important role in maintaining key
ecosystem utilities and biodiversity.
o improve the connectivity between
aquatic habitats
o transfer both precipitate and
nutrients on the landscape, and into
the marine environment.
o as enlarged fish production,
revive of groundwater resources,
and maintenance of recreational
surroundings
7. EFFECT OF FLOOD TRAGEDY TO ENVIRONMENT
7
➢ Negative effects :-
• Loss of habitation
• Dispersion of weed species
• Release of impurities
• Lower fish production
• Loss of wetlands utility
• Harm of recreational areas
➢ Elimination of vegetation in and nearby
rivers:-
• Increased channel dimension, dams, levee bank
• Catchment clearing completely work to reduce
the hill-slopes, rivers and floodplains
• Increase the erosion
• Allocation of both sediment and nutrients
9. It have two type suggestion/solution to overcome the
flood tragedy which are structural or nonstructural
9
SUGGESTION
STRUCTURAL NON - STRUCTURAL
Changing the characteristic
of flood by Dams, levees,
and floodwalls and decrease
probability of flooding at
interest location
Changing the step of impact or expose
of flooding and prevent any altering on
the characteristic
10. THERE HAVE MANY SOLUTION WAS CREATED TO
PREVENT FLOOD TRAGEDY. SOME OF THE SOLUTION
WAS LIST ARE :-
10
SOLUTION
1. Introduce better flood warning systems
2. Modify homes and
businesses to help them
withstand floods
11. 3. Construct buildings
upstairs flood levels
4. Challenge climate change

🌏
Basic wet flood-proofing measures for a residential
structure (Source: Linham and Nicholls, 2010)
12. 5. Rise of expenses on
flood defenses
6. Protect wetlands and
introduce plant trees
strategically
12
7. Reestablish rivers to their
natural developments
Before and after flood restoration
13. 8. Make known a water
storage capacities
9. Expand soil
conditions
13
🌏
10. Create
supplementary flood
barriers
14. Levees, Floodwalls,
Seawalls, and Other
Appurtenant Structures
Designed of the structure to
prevent floodwater. Make a
reaching zone cause surge
storm expose to risk.
MITIGATION MEASURES (STRUCTURE)
Dams
Conserve floodwaters before
they reach areas at risk by a
barriers that possess
hydrologic flows and dams.
14
🌏
15. Floodways, Spillways, and
Channels
To bring floodwaters around a
community by constructing
floodways, spillways, and
channels
MITIGATION MEASURES (STRUCTURE)
Improved Levee Design or
Modification
Come up with improve or
design levees to avoid
continuous stress that
threatens their integrity
15
16. Controlled Overtopping and Breaching of.
Control the risk of levee overtopping will extensive might the
consequences can be terrible.
MITIGATION MEASURES (STRUCTURE)
16
A gated overflow spillway that would control flows into a desired area
17. Levee Armoring
The system that make
a less vulnerable to
erosion of flooding or
overtopping.
Seepage Berms and Cutoff Walls
The system to stop the flow process
through and under of levee 17
Example of an armored levee in Japan
MITIGATION MEASURES (STRUCTURAL)
18. ➢ Structure Elevation
Development the structure
to control flood levels and
predictable alternatives
MITIGATION MEASURES (NON - STRUCTURAL )
18
Levee seepage and control methods
19. ➢ Natural Systems
A system to rehabilitate
or build wetlands and
replant periodically
created to store flood
water flow
MITIGATION MEASURES (NON - STRUCTURAL )
➢ Risk Mapping
Efforts to map to those who live or work
in areas often flooded and in the area of
shooter so that they can make an
informed decision and more strategy in
reducing floods

Example of a home from follow dry and wet low-level flooding.🏃 🏃
MITIGATION MEASURES (NON - STRUCTURAL )
21. Land-Use Planning and
Zoning
the wise use of land
contributes to non-
structural flood reduction
action and is an in effect
tool for reducing risk at
the public level.
NON - STRUCTURAL MITIGATION MEASURES
.
21
Construction Standards
and Building Codes
Construction standards and
building codes can be
established at all level of
well-known especially
government.
22. Insurance
It is necessary to take
insurance where the
financial risk of mortgages
on the landslide is slowly
exchanged and goes towards
premiums from those who
handle your insurance
Acquisition and Relocation
The process of retrieving
plagues and flood-prone
property on a continuing
center caused significant
damage and required FEMA
and USACE-supported flood
reconstruction projects.
22
NON - STRUCTURAL MITIGATION MEASURES .
23. CHALLENGING OF IMPLEMENT
➢ Enhancement of
activities for incentive
improve of live system,
food safety and increase
of infrastructure
construction are a
major complication to
the natural system due
to population increase
➢ Intensify the hydrological
cycle because of Climate
change
➢ sea level rise affects the
risk of flooding in coastal
areas and estuaries.
23
24. CHALLENGING OF IMPLEMENT
➢ Rapid growth and
overpopulation of the city
with its surface is never
transparent to lead to
improved runoff and
highlight downstream
floods
➢ The lack of alternate land
used for economic
undertakings in several
nations
➢ Extensive deforestation
driven by farming,
mining or urbanization

and sanity
United Nation Sustainable Goal
2030
Upgrading water quality by
removing the scars, reduce
release of chemicals
hazardous and eliminating
dumping.
27. Identify potential un-ethical problem
27
Media mindset
The response of community
authorities through or after
disaster is: “everything is under
control, all of the obligatory
actions will be taken by us as
soon as possible”. Along with a
defensive attitude, progress is
prevented by a resistance to
cooperation with “outsiders”.
Public authorities’ attitude
The mass media’s mindset and
attitude after a disaster have been
one of the most irritating, as
charged by study participants,
stating that reporters can
recklessly block the relief efforts
just to get closer images. Images
of dead and wounded people might
be published without any respect
to personhood rights.
28. Identify potential un-ethical problem
28
Relief organizations approach
Several participants complain that international relief organizations
might approach in a paternalistic and imperious manner to local
organizations and society. On the other hand, participants note a
contradiction as they think that relief workers’ qualifications and
medical interventions might be questionable, and some organizations
do not arrive to the scene self-sufficient and therefore create an extra
burden on the already-limited local resources
