3. Disaster
• Disaster is a natural or human , caused
phenomenon, which causes serious
disruption of the functioning of a
community or a society causing
widespread human, material, economic
and environmental losses which elicited
the ability of the affected community,
society to cope using its resources.
• Floods are a common feature in the
country that occur every year inmany
parts including South India.

4. INTRODUCTION
Aflood occurs when the Geomorphic
Equilibrium in the river system is disturbed
because of intrinsic or extrinsic factors or
when a system crosses the geomorphic
threshold.
(a) Flooding in a river due to aggradation of
river bed (intrinsic threshold);
(b) Flooding in a river due to heavy rainfall
(extrinsic threshold)
Floods in major cities especially
during rainy season are proving to
disastrous not only to the
environment but also have serious
implications for human life and
property.

MANAGEMENT

5. TYPESOFFLOODS
• Types of floods
•Flash floods
•River floods
•Coastal Floods
•Urban Flood
• According to their duration flood can be divided into different categories:
•Slow-Onset Floods: Slow Onset Floods usually last for a relatively longer period, it may last for
one or more peeks, or even months.
•Rapid-Onset Floods: Rapid1Onset Floods last for a relatively shorter period, they usually last for
one or two days only.
•Flash Floods: Flash Floods may occur within minutes or a fe1w hours after heavy
rainfall, tropical storm, failure of dams or levees or releases of ice dams. And it causes the
greatest damages to society.

6. The soil becomes
saturated and
overland flow and
through flow reach
the river and
discharge increases.
Overland flowarrives
first.
The time from peak rainfall topeak
discharge is the LAGTIME.
The discharge starts to
fall slowly as water is
added from through
flow and groundwater
flows which are much
slower.
The base flow supplies
the river with water
between storms and
keeps it flowing in
summer.Rainfall is intercepted
or infiltrated into the
soil moisture store
Start of the storm there is a
slow rise in discharge, as onlya
small amount of water falls
into the channel

Krishna River in Karnataka.
This water along with rain
water reached Andhra Pradesh
near the Srisailam dam. It
causes a hevy floods in
andhrapradesh

8. Causes of floods

9. FACTORS
VEGETATION COVER
This varies seasonally. The type and
amount will affect interception and
stemflow/throughfall. Overland flowis
reduced. Lagtime will be increased.
ROCKTYPE
Impermeable rocks prevent groundwater
flow and encourage through flow and
overland flow. These rocks will decrease
lag time. Permeable rock will have the
opposite effect.
LAKES&RESERVOIRS
These will store floodwater and
thus reduce lag time andcontrol
river response to heavy rainfall.
SOILTYPE&DEPTH
Deep soils store more
water, pipes in the soil
encourage through flow.
Soils with small pore
spaces will reduce
infiltration and increase
overland flow.
LAND USE
Impermeable surfaces
created by urbanisation will
reduce infiltration and
encourage overland flow.
Different types of crops
affect interception rates e.g.
cereals 7-15%.
RAINFALLINTENSITY&DURATION
Intense rain will increase overland
flow and reduce lag times. Gentle
rain over a longer time will allow
more infiltration.
SLOPES
Steep slopes will encourage
overland flow and gentle
slope will slow run off down.
CLIMATE
The distribution of rainfall over the
year and the temperatures will
affect the lag times.

10. FLOODS IMPACTS
• Human Loss
• Property Loss
• Affects the Major Roads
• Disruption of Air / Train / Bus services
• Spread of Water-borne CommunicableDiseases
• Communication Breakdown
• Electricity Supply Cut off
• Economic and Social Disruption
• Increase in Air / Water Pollution

11. Flood forecasting
• Anticipating floods before they occur allows for precautions to be taken and
people to be warned so that they can be prepared in advance for flooding
conditions.
• For example,
– Farmers can remove animals from low-lying areas and utility services can put in place
emergency provisions to re-route services if needed. Emergency services can also make
provisions to have enough resources available ahead of time to respond to emergencies as
they occur.
• In order to make the most accurate flood forecasts for waterways, it is best to
have a long time-series of historical data that relates stream flows to
measured past rainfall events
• Radar estimates of rainfall and general weather forecasting techniquesare
also important components of good flood forecasting.

12. Flood Control
• In many countries around the world, waterways prone to floods are often carefully
managed. Defences such as levees, bunds, reservoirs, and weirs are used to prevent
waterways from overflowing their banks.
• In the riparian zone near rivers and streams, erosion control measures can be taken
to try and slow down or reverse the natural forces that cause manywaterways
to meander over long periods of time.
• Flood controls, such as dams, can be built and maintained over time to try and
reduce the occurrence and severity of floods aswell.

13. Flood benefits
• Floods (in particular more frequent or smaller floods) can also bring many
benefits, such as
– Recharging ground water,
– Making soil more fertile and increasing nutrients in some soils.
• Flood waters provide much needed water resources in arid and semi-arid regions
where precipitation can be very unevenly distributed throughout the year.
• Freshwater floods particularly play an important role in maintaining ecosystems in
river corridors and are a key factor in maintaining floodplain biodiversity.
• Flooding can spread nutrients to lakes and rivers, which can lead to
increased biomass and improved fisheries for a few years.
• For some fish species, an inundated floodplain may form a highly suitable location
for spawning with few predators and enhanced levels of nutrients or food.
• Fish, such as the weather fish, make use of floods in order to reach new habitats.
Bird populations may also profit from the boost in food production caused by
flooding.

22. Total flood damage state wise and for
the union territory of Delhi
 The macro-flood zones of
India may be broadly grouped
into the following zones:
 (a) Brahmaputra River Basin,
 (b) Ganga River Basin,
 (c) North-West Rivers Basin,
and
 (d) Central India and Deccan
Rivers Basin.

23. 2012 Brahmaputrafloods
This was another sorrow caused to Assam in recent years.
In July 2012, Brahmaputra and its tributaries showed its
wrath and since it was natural but it grabs a spot atnumber
2 and eye-catching event because the main area which was
affected included Kaziranga National Park, a park which is
the natural habitat of Rhinos. It cause a death of 540
animals including 13 Rhinos. The main reasons behind this
calamity is the deforestation in the area of passing by of
Brahmaputra.

24. 2010 LadakhFloods.
It was 6th August 2010, when the series of
natural disasters started to take place in
Ladakh, a regional part of J&K( Jammu and
Kashmir). It was accompanied with
cloudburst, debris flows and Flash floods from
Himalayan. Causality was less than 300 but
a great loss of property was reported. Areas
of Leh were also affected and it caused a loss
of total Rs.133 crores INR.

25. 2005 : Maharashtra flood
This was the major and the most devastating
disaster occurred in Maharashtra, mainly
engulfing areas of
Mumbai, Chiplun, Khed, Kalyan, Ratnagiri
and Raigad. The main problem arose with the
people on the road and which caused a traffic
jam and with it came the loss of people. Atotal
of 5000 people were reported for the death
toll. The date 26 July 2005 has been marked
as one the BLACKDAYin the history of
Mumbai.

26. 2004 Bihar Flood
Being considered as a flood prone area, Bihar is again in
the list because of 2004 flood which it suffered. It was
stated that a total of 883 people lost their lives and more
than 3000 animals were killed. One of the most
horrifying disaster caused almost a loss of Rs.
1,03,049.60 Lakh. Rivers, primarily, Gandak, Kosi,
Mahananda, Bagmati, Budhi had already crossed the red
mark while on the other hand Ganga first time in its
history crossed the red mark in Farrakka Barrage.

27. STATEPERSPECTIVE
• Latest reports said 150
villages in Srikakulam,
Visakhapatnam, Krishna,
Guntur and the east and west
Godavari districts were
submerged. Around 67,000
people had been evacuated.
Crops spread over 2.5 lakh
hectares of farmland were
under water and schools
remained shut.(2012)

31. Approaches &measure for long ,short
term protection from floods in India
• Attempts to modify the floods: involves flood protection by physical
measures such as
• Construction of embankments
• Construction of detention reservoirs
• Channel improvements etc.
• Attempts to modify the susceptibility to flood damage: involves action
designed to reduce the vulnerability of property and other developmental
activities in the flood plains to the floodhazard
• Attempts to modify the loss burden: Consists of actions to modify the
incidence of losses, by spreading them over a large segment of
community.
• Bearing the loss: Bearing the loss means living with floods

• Performance evaluation of a large number of FMschemes be carried out and their impact
on the socio economic development of the protected area beassessed.
• The use of flood plains be regulated and a suitable legislation for flood plain zoning be
enacted and enforced.
• Water Resources planning and construction be basin wise and basin organisations be set up.
• Storages in various forms is an important component of the package of measures for FM
and flood space in reservoirs be provided to the extent feasible and flood control not
relegated to a non- priority activity as against competing water requirements for
hydropower and Irrigation purposes.
• International dimensions of problem of floods be kept in mind and the GOI should play an
important role in the matter.
• Requisite funds be made available for construction of new and maintenance of existing
works.
• Emphasis be laid on research, education and training on FM.

Map of India showingAP

57. Location
• The city is situated at the foot of a low range
hills on the northern bank of the river
Krishna with its cardinal points as 16° 31’
North latitude and 80° 37’East
longitude, around 70 km away from thecoast.

58. Topographic Details
• The land lay of Vijayawada is characterized by four canals,
four hills and the holy river Krishna. Vijayawada when
approached from Guntur is welcomed by the historic gates
across the holy river Krishna. The way to Machilipatnam
runs parallel to Budamerru canal and crosses two other
Canals
There are four major hills:
a) Indrakiladri hill
b) Machavaram
c) Gunadaa Hill
d) Moghalrajapuram hill
e) Gollapalem Gattu Hill

59. Krishna River
• The River Krishna takes of its origin in the western Ghats at an elevation
of (+) 1336 Mts and runs for a length of about 1400 Kmand runs
through Vijayawada city and joins at Bayof Bengal The length of Krishna
River up to Prakasam Barrage is about 1310 km and the length from
Prakasam Barrage to Puligadda Aqueduct is 64.00 kms.
• The flow of the river is managed partially by the Nagarjuna Sagar dam
which is located to the west of Krishna District and Prakasam Barrage
which is located at the beginning of the city.

60. Krishna river flow details and distance of dam to dam
The Krishna Flood bank Above Prakasam Barrage is about 13KM and
bellow flood bank is 6.40 Kmwhich creates havoc in flood season whichstarts
from June to December. Water release from barrage with 4,12,734
to 10,94422 Cusecs is been observed over the years.

66. Reasons for Krishna Flood
 This region receives maximum rainfall both by southwest and retreating
monsoons.
 The primary reason for the flooding is the unauthorized settlementsalong
the river which had taken place due to lack of planning and enforcement.
 Vijayawada is located on the line which separates the delta-irrigatedlands
 Flood bank below barrage is about 6.40 Kmwhich creates havoc in flood
season from June to December.
 High Water release at time from barrage with 4,12,734to 10,94422
Cusecs of water released in various years.
 Developmental activities like sluice connectivity to into the river iscausing
back water(3 sluices connected into river)
 Bund cutting for public private developmental activities (ex: sluice, storm
water drains) approach roads for biggervehicles.
 Allotting the residential areas officially in flood zone. Ex:Police colony.

67. Contd…
• trespassing the river bunds by people
• damage to the river bunds byrodents
• Breach occurrence and damages occurred to the
flood bank with slips and erosion.
• Negligence and helpless condition making people
to stay at the houses even after passing the
warnings
• With little authoritative power over the
settlements along the flood banks, the irrigation
department is unable to attend swiftly in
vulnerable areas.

72. MITIGATION
 Mitigation measures are very important phase of disaster management. They will
help to reduce the loss and increase the capacity of people in managing the
disasters.
The potential forecast outlook can be translated into early warning messages and
initiate preventive/preparedness actions.
• Asper the building byelaws 1981, no permission to construct a building on site
shell be granted , if the site is with in 9 meters of the highest water mark of a
tank
• Further the authority may require the floor of the lowest styorey of such building
to be raised above the normal minimum flood level of the adjoining to ground or
to such other level as the authority may prescribe Shift or restrict the people living
in flood banks to safe place by providing all aminities
• Krishna Bund strengthening at Krishna lanka, ranadheevinagar, Bhupesh Gupta
nagar
• Krishna bund construction from police colony to yanamala kuduru
• Raising the free board of Krishna flood bunds from 1.5 metre to 2 meters.
• Shift the habitants of the flood zone of Budameru temporary or permanent to safe
shelters after announcing the warning
• Stop plowing / occupying the budameru bund from singh nagar to NSCBose
nagar

73. Contd…
• Providing Road side rain water drains at banadar road
• Providing Road side rain water drains Ayyappanagar Road
• Providing Under ground drainage and sewer lines and
construction of sump cum [Pump house

express itis safe to do so
• Stockpile emergency building materials If indoors:
•Turn on battery operated radio toget
latest emergency information
•Get pre-assembled emergency
supplies
•If told to leave, do soimmediately.
If outdoors:
•Climb to high ground and stay there
•Avoid walking through any
floodwaters.
•If in a car, turn around and go another
way; if your car stalls, abandon it
immediately and climb to higher
ground.
During an evacuation:
•If advised to evacuate, do so
immediately to avoid flooded roads,
being sure to follow recommended
evacuation routes and listen to radio for
evacuation instructions
• Help neighbors whom may need assistance
• Install check valves in sewer traps to • Use extreme caution when entering
prevent flood waters from backing up in buildings
sewer • Inspect foundations for cracks or other
