6. River and the City

7.  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

Highest flood record
3211cumecs
Panshet Dam Failure (1961)
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
I. Displacement of Families in the river banks
II. Destruction of private property on the river banks
III. Destruction of Biodiversity on the river banks
IV. Disruption of Transport and communication systems
V. Destruction of drainage and sewage system
VI. Eroding of river banks
VII. Adverse effect on Public Health

16. Families Rehabilitated during Floods
Year No. of Families Affected by Floods
2004 1623
2005 5345
2006 5098
2007 200

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)
2006 - 2007
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

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.

 Supply flood update to Flood control department of PMC

28. FUTURE ACTION PLAN FOR
FLOOD FORECASTING &
DISASTER MANAGEMENT

29. Salient Features
1. 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
2. Prevent encroachment of the river and streams by
declaration of Biodiversity Restoration Zones along the
banks
3. Use of Gabions/Reno Mattresses on river banks for
stabilisation and allow percolation of water

30. 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.
Designation of Floodway (River Channel) and High Flood Level Components
Development Zone

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
