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 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 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 citys lifeline and no other city in the country can boast of having three Rivers running through it The Rivers formed the citys lifeline and no other city in the country can boast of having three Rivers running through it KHADAKWASLA DAM LAKDI PUL BUND GARDEN BRIDGE

9 A Disaster Strikes Pune at 2:00pm on 12 th 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 Reduction in Carrying Capacity of the river Encroachment in river and tributaries (nullahs) draining into the rivers Encroachment in river and tributaries (nullahs) draining into the rivers Disposal of Debris and solid wastes including plastics Disposal of Debris and solid wastes including plastics Lack of Remote Rain Gauging and Telemetric Early Warning System 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 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 Increase in River carrying capacity by Dredging of 1.50 MCM of silt Dredging of 1.50 MCM of silt Excavated Debris is reused for construction of roads Excavated Debris is reused for construction of roads Protection Protection Construction of 1.50 km of protection wall to protect 10 major flood prone areas Construction of 1.50 km of protection wall to protect 10 major flood prone areas River flow (reduced afflux) River flow (reduced afflux) Removal of an old Stone masonry bund Removal of an old Stone masonry bund Removal of central section (100m long and 5 m high) of Bundgarden bund Removal of central section (100m long and 5 m high) of Bundgarden bund

20 Each hour Khadakwasla Dam flows above cusec Water level of Mulshi dam start increasing above 1980 ft Irrigation Department Mulshi- Collector office Public Relation officer Flood control Department Pune Municipal Corporation Authority NGO, Social services Organisation etc Media (hourly updates) Municipal Commissioner and Police Commissioner work on next action plan Take Action PMT, Road Traffic, health dept etc Municipal Regional Offices Organisational Structure for Disaster Management

21 Role Played by Regional Offices At present 39 Rehab Centres are available Organisational Structure …..contd

22 Discharge from Khadakwasla Action done cumecs (40000 cusecs) DMP Flood Alert cumecs (50000 cusecs) DMP operations initiated Benchmarks for Initiation of Disaster Management Plan

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 High Flood Level Floodway Development Zone Submersible Zone Development Zone Submersible Zone

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

32

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

34 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 Conclusions
