1 THE INTERNATIONAL CONFERENCE ON FLOOD MANAGEMENT BAJA, HUNGARY HIDRO CLB CONSULT NOVI SAD Kisačka 64 A AN ANALISIS OF CITIES ENDANGERMENT OF FLOODS ON THE EXAMPLE OF NOVI SAD Rade Milutinović, dipl.ing rademilu@yahoo.com 1

2 REASONS FOR THE TREAT OF NOVI SAD HYDROLOGICAL GEOGRAPHICAL MORPHOLOGICAL IMPORTANT EVENTS IN THE PAST 2

3 ABOUT FLOODS - FLOODS ARE A NATURAL PHENOMENON - LIFE BY THE RIVER IS DESEPTIVE PEACE AND A LABILE BALANCE - SAFETY BY THE RIVER - BATTLES AND WAR - IGNORANCE END FRIVOLITY 3

4 FLOODS ARE A CATASTROPHE FOR HUMAN COMMUNITIES - THE FLOOD BECOMES A CATASTROPHE WHEN THE RESPONSIBLE PEOPLE THINK THAT IT WON T HAPPEN 4

5 FLOODS MEAN A STRUGGLE FOR LIFE 5

6 FLOODS = DAMAGES 6

7 FLOODS = MUD, POLLUTION, CONTAMINATION 7

8 FLOODS = EFFORT, FIGHT TO SAVE... FLOODS BRING FEAR, TIREDNES AND SLEEPLESSNESS FLOODS PUT PEOPLE AND STAE STRUCTURES ON GREET TEMPTATION 8

9 FLOODS ARE EVACUATIONS AND COLLECTIVE ACCOMMODATIONS 9

10 FLOODS AND CATASTROPHIC FLOODS - THE DIFFERENCE BETWEEN THE TWO IS IN THE DAMAGE THAT ARISES - DAMAGE DOES NOT DEPEND ON THE DEGREE OF FLOODING, BUT RATHER ON WHAT IS FLOODED - WHEN THE CITY FLOODS - DAMAGE IS HUGE, - IN UNTREATED AND AGRICURTURAL AREAS, THE DAMAGE CAUSED BY FLOOD IS MUCH LESS 10

11 WE CAN T PREVENT ALL FLOODS WE HAVE TO REDUCE THE DAMAGE TO A TOLERABLE LEVEL 11

12 CITIES ARE THE GREATEST VALUE OF THE DEFENDED TERRITORY CITIES NEED TO PROVIDE A HIGHER LEVEL OF PROTECTION THAN THE SURROUNDING TERRAIN CITIES SHOULD BE PROTECTED IN THE WAY TO BECOME ISLANDS IN THE MIDST OF FLOODED AREA 12

13 EVENTS WHICH WARN US THAT CATASTROPHIC FLOOD IS APPROACHING SITUATION No 1. HIGH WATER UPSTREAM OF NOVI SAD 13

14 FLOOD IN PASSAU, KM OF DANUBE 2013, 1501, 1595, 1954, 1787, 1862, 1899, 1895, 2002, IN THE PAST FIVE HUNDRED YEARS EIGHT TIMES - IN THE 21 ST CENTURY, FOR 13 YEARS TWICE year = 1501 year + ~50cm 14

15 HIGH WATER OF DANUBE UPSTREAM OF NOVI SAD MAXIMUM AMOUNT OF WATER ; WATER COINCIDENCES, m god. Over 10,000 m and 1954 Over 10,000 m3 / s and

16 BRATISLAVA THE FLOW OF DANUBE WAS m3/s THE WATER LEVEL WAS EXCEEDED BY 41 CM m3/s m3/s m3/s 16

17 YEAR BUDAPEST THE HISTORICAL MAXIMUM LEVEL OF DANUBE WAS EXCEEDED BY 31CM 17

18 SITUATION No 2. THE LARGEST FLOWS NEAR NOVI SAD 18

19 Year NOVI SAD - THE LARGEST FLOW M3/S, - FIVE BURSTS OF EMBANKMENTS AND SIGNIFICANT WATER SPILLAGE - THE MEASURED WATER LEVEL WAS 778 -IF THERE WAS NO PENETRATION OF THE DAM, THE WATER LEVEL WOULD HAVE BEEN 830 -FOR A HIGH WATER VALUE OF 778 WAS TAKEN -THE REAL VALUE OF THE HIGH WATER IS THE EXISTING EMBANKMENTS SHOULD BE 30 CENTIMETRES HIGHER 19

20 THE INFLUENCE OF UPSTREAM PENETRATIONS OF THE DAM ON TE DANUBE LEVEL IN NOVI SAD 20

21 SITUATION No 3 - THE WIDTH OF DANUBE IN NOVI SAD 21

22 THE WIDTH OF DANUBE IN NOVI SAD IS 300 M THIS IS THE SMALLEST WIDTH OF THE MIDDLE DANUBE 22

23 ONE UNFAVORABLE SITUATION IN THE CASE THAT WATER GETS HIGHER THAN IT HAS EVER BEEN SITUATION No. 4 - THE RULE IS - NO DEFENSE WITHOUT ARMY - TOTAL OF JNA SOLDIERS (14000 PER DAY) PARTICIPATED IN DEFENSE AGAINST THE FLOOD IN NOWADAYS, IT WOULD BE IMPOSSIBLE TO ENGAGE THAT NUMBER OF PEOPLE - 23

24 SITUATION No. 5 - HYDROTECHNICAL HUB OF EUROPE 24

25 HYDROGRAFIC MAP OF OUR AREA 25

26 SITUATION No. 6. CONFIGURATION OF THE TERRAIN IN THE CITY NOVI SAD WAS BUILT IN DANUBE BASIN FOR HIGH WATERS 26

27 Angle 77,00 mnm. WATER LEVEL 527 REGULAR DEFENSE IS ANNOUNCED AT WATER LEVEL

28 Angle mnm. WATER LEVEL 577 WATER LEVEL 570 APPEARED IN 2005; 590 APPEARED IN 1977; 571 APPEARED IN

29 Angle 78,00 mnm. WATER LEVEL 627 WATER LEVEL 638 APPEARED IN 1981; 644 APPEARED IN

30 Angle 78,50 mnm. WATER LEVEL

31 Angle 79,00 mnm. WATER LEVEL 727 They were in and 1975 Extraordinary defense

32 Angle 79,50 mnm. WATER LEVEL 777 THE HIGHEST WATER LEVEL THAT APPEARED 1965 WAS

33 Angle mnm. WATER LEVEL 827 HUNDRED YEAR REAL WATER 33

34 Angle 80,50 mnm. WATER LEVEL 877 THE ANGLE OF CONCRETE WALL AT THE QUAY IN NOVI SAD CORRESPONDS TO THE WATER LEVEL OF

35 Angle 81,00 mnm. WATER LEVEL 877 -ANGLE OF THE CROWN OF THE EMBANKMENT IS 920 CALCULATING 1000 YEARS HIGH WATER ACCORDING TO ESTIMATION FROM

36 Angle 81,50 mnm. WATER LEVEL YEARS HIGH WATER PER ACCOUNT FROM 2007.GOD FLOOD 36

37 HOW TO HELP OURSELF? WHAT CAN BE DONE? FIRST: -ACCEPT THAT FLOOD MAY OCCUR SECOND: -THERE IS NO TIME -IMMEDIATE ACTION -CHANGES ARE IN PROGRESS THIRD: -DEFINE THE MOST UNFAVORABLE SCENARIO AND PROTECT FROM IT FOURT: -THE COST OF PROTECTION IS 5 10% OF THE INEVITABLE DAMAGE 37

38 GOLDEN FLOOD PROTECTION RULES FIRST: PREPARATION, PREPARATION, PREPARATION SECOND: ORGANIZATION, ORGANIZATION, ORGANIZATION THIRD: THE PROBLEM THAT WE AVOID TODAY, WE WON T HAVE TO SOLVE TOMORROW. IT WILL BE UNSOLVABLE TOMORROW 38

39 POSSIBLE SOLUTIONS TO FORM A FLOOD MANAGEMENT SYSTEM WHAT IS FLOOD MANAGEMENT? ORGANIZATION AND SYSTEM OF MEASURES TO CONTROL FLOODS THAT CAN T BE AVOIDED OR PROTECTION OF THE MOST VALUABLE PROPERTY IN THE PROTECTED TERRITORY AS THE RIVER GROWS DEFENCE AGAINST IT WHEN THE FLOOD COMES FLOOD MANAGEMENT 39

40 THE MOST IMPORTANT MEASURE OF FLOOD MANAGEMENT INCREASE THE LEVEL OF PROTECTION OF THE MOST VALUABLE PROPERTY TO FORM CROSS - SECTIONAL AND COMPREHENSIVE EMBANKMENTS OF MOBILE EQUIPMENT CONDITION: - DEFINE MOBILE DEFENCE LINES, - DEFINE THE REQUIRED HEIGHT AND DIMENSION, - GET MOBILE EQUIPMENT, - PREPARE MOBILE INSTALLATION LINES, - TRAIN THE FORMATION OF TRANSVERSE LINES OF DEFENSE 40

41 CONCRETE L ELEMENTS * ( *EUROPEAN PATENT No ) POSSIBLE SOLUTION 41

42 MOBILE BARRIER ALONG THE ROAD No.1 42

43 MOBILE BARRIER ALONG THE ROAD No. 2 43

44 MOBILE BARRIER ALONG THE EMBANKMENT No. 3 44

45 MOBILE BARRIER - WALL HANGING No. 4 45

46 THE WAREHOUSE OF THE L ELEMENTS NEXT TO THE PLACE OF APPLICATION 46

47 THE STORAGE OF THE L ELEMENTS IN THE FORM OF A SUMMER STAGE NEXT TO THE PLACE OF APPLICATION 47

48 THE STORRAGE OF PARTIALLY BURIED L ELEMENTS 48

49 THE STORRAGE OF COMPLETELY BURIED L ELEMENTS 49

50 THE STORAGE IN THE FORM OF A FLAKE 50

51 REINFORCEMENT OF DEFENSE LINES DRIVEN THE WATERTIGHT BARRIER INTO THE GROUND REINFORCEMENT OF EXISTING DEFENCE LINES, HYDRAULIC REINFORCEMENT OF THE BASE FOR THE MOBILE BARRIER 51

52 MAKING A WATERTIGHT BARRIER DRIVEN IN THE SOIL 52

53 WATERTIGHT BARRIER ALONG THE ROAD 53

54 REINFORCEMENT OF EMBANKMENT WITH WATERTIGHT BARRIERS 54

55 WATERTIGHT BARRIERS IN THE EMBANKMENT 55

56 WATERTIGHT BARRIERS AROUND INDUSTRIAL OBJECTS 56
