3. Introduction
“Punyanagari
The City of Virtuous Deeds”

6. River and the City

7. History
Pune traces its origins to an agricultural settlement by the name of Punnaka in the 8th century AD; also called Punyapur or Punyanagari, “The City of Virtuous Deeds”
The city is built on the confluence of the three rivers Mutha, Mula and Pavana. These Rivers were believed to have Mythic Cleansing Powers
The Rivers formed the city’s lifeline and no other city in the country can boast of having three Rivers running through it
KHADAKWASLA DAM
LAKDI PUL
BUND GARDEN BRIDGE

8. Importance 8th Largest Urban Agglomeration in India
Population – 4.7 million 6%
Cultural Capital of Maharashtra
‘Oxford of the East’
‘Detroit of India’
Rapidly Growing Economy powered by IT, Manufacturing and Services
Twenty bridges cross the river along 27 km of lenght

9. A Disaster Strikes Pune at 2:00pm on 12th July 1961 !!!
Panshet and Khadakwasla Dam Failure results in a Major Flood in the city of Pune

10. FLOOD SCENARIO IN PUNE

11. History of Floods in Pune
Discharge in Cumecs
Years

12. Flood Frequency Analysis was conducted for 1940 to 2007 of the maximum discharge data from Khadakwasla
The 1958 flood with a magnitude of 3211 cumecs is the highest flood recorded.
The mean annual peak flood is about 1165 cumecs.
Every decade had recorded one severe flood during the last six decades (1944, 1958, 1961, 1976, 1976, 1983, 1997 and 2005).
The post 1961 period shows a significant decline in the peak flood magnitudes and increase in the flood variability. This could be attributed to the increased control of dams located on the river, such as Temghar and Varasgaon that were constructed during the post-1961 period.

13. CAUSE AND EFFECT

14. Causes Reduction in Carrying Capacity of the river
Encroachment in river and tributaries (nullahs) draining into the rivers
Disposal of Debris and solid wastes including plastics
Lack of Remote Rain Gauging and Telemetric Early Warning System

15. Effects Displacement of Families in the river banks
Destruction of private property on the river banks
Destruction of Biodiversity on the river banks
Disruption of Transport and communication systems
Destruction of drainage and sewage system
Eroding of river banks
Adverse effect on Public Health

16. Families Rehabilitated during Floods
Source : Slum Department, PMC
Improvement in our Disaster Management Ability has resulted into a large reduction in the number of Flood Affected Families

17. CURRENT FLOOD PROTECTION MEASURES

18. Disaster Management Initiative by Pune Municipal Corporation (PMC)
PMC embarked upon preparation of a a comprehensive Disaster Management Plan
Involving all agencies of the local self government law enforcing agencies, state govt and education institutes
MAY 2007 DMP WAS PROMULGATED

19. Engineering Measures for Disaster Management by Pune Municipal Corporation (PMC)
Increase in River carrying capacity by
Dredging of 1.50 MCM of silt
Excavated Debris is reused for construction of roads
Protection
Construction of 1.50 km of protection wall to protect 10 major flood prone areas
River flow (reduced afflux)
Removal of an old Stone masonry bund
Removal of central section (100m long and 5 m high) of Bundgarden bund

23. PMC Departments working towards Flood Management
Fire Brigade Authority
River Improvement and Garden Superintendent Department
Pune Maha Nagarpalika Parivahan Mahamandal Ltd
Health Department
Vehicle Department
Public Relation Department
Education Department
Electricity Department
Irrigation Department

24. Fire Brigade Authority
Training of experts from this department to other officer for planning & evacuation.
Evacuation of people and property from site
Supply of various equipment like pumps, cranes, boats etc where ever required
Lifting of collapse articles like fallen trees etc during heavy rains
River Improvement and Garden Superintendent Department
Desilting of almost 1.50 MCM
Deposition of debris for construction of DP road
Disposal of excess debris at relevant location
Construction of 1.50 km of protection wall which covers almost 10 major flood prone areas

25. Pune Maha Nagarpalika Parivahan Mahamandal Ltd.
Release of public transport
Make vehicles available wherever required
Make drivers available
Get updates about traffic diversions and inform it to the drivers.
Keep stock of fuel and other material required
Health Department
Make Doctors, Pharmacist, auxiliary nurse etc available.
Supply medicines
Ambulance

26. Public Relation Department
Vehicle Department
Make wireless vehicles, truck and drivers available
Coordination with fire brigade authorities through these wireless vehicles
Public Relation Department

Teachers and other staff also provide help in this respect

27. Electricity Department
As the electric supply is completely damage during floods provide generators to evacuation teams
Provide temporary electric wiring at rehabilitation centers
Provide emergency lamps
Irrigation Department
Control discharge at each of the dams
Supply flood update to Flood control department of PMC

28. FUTURE ACTION PLAN FOR FLOOD FORECASTING & DISASTER MANAGEMENT

29. Salient Features
Installation of Remote Rain Gauging, level gauging and telemetry system for early warning to control peak discharge from Khadakwasla to within 50,000 Cusecs during the rainy season
Prevent encroachment of the river and streams by declaration of Biodiversity Restoration Zones along the banks
Use of Gabions/Reno Mattresses on river banks for stabilisation and allow percolation of water

30. Development Zone Development Zone
Mapping and Delineation of the flood-prone area by use a probability-based analysis wherein systematic records and historical information on past flooding are used to develop a relation of probability of occurrence versus magnitude.
Development Zone
Submersible Zone
Floodway
High Flood Level
Submersible Zone
Development Zone
Designation of Floodway (River Channel) and High Flood Level Components

31. Comprehensive Non Structural Flood Management System
The proposed system can be divided into three important sub systems viz.
Telemetry System
Management Information System
Decision Support System

33. Telemetry System gathers hydrological and meteorological data such as
Rain fall data from rain-gauge stations in the catchment
Water level data from river gauge stations
Reservoir level data from level sensors installed at the reservoirs
Data is gathered without any human intervention
Collected data is then presented to the Management Information System and the Decision Support System
Based on the received data and the pre-fed conditions/parameters/rules the system computes information required for controlling discharge of water

34. Conclusions
Our experience of PMC has shown that initiative by the local self governing body can control & reduce the magnitude of disaster and effectively manage a disaster
